World War I, or the First World War, also known as the Great War, was a global conflict between two coalitions: the Allies and the Central Powers. One of the deadliest conflicts in history, World War I caused 15 to 22 million deaths, including those resulting from war crimes and genocides. The war also contributed to the spread of the Spanish flu pandemic. The conflict saw important developments in weaponry, including machine guns, artillery, aircraft, chemical weapons, and tanks.

Battles 70
August 1914
Battle of Tannenberg
The Battle of Tannenberg, also known as the Second Battle of Tannenberg, was fought between Russia and Germany between 26 and 30 August 1914, the first month of World War I. The battle resulted in the encirclement and the almost complete destruction of the Russian 2nd Army by the German 8th Army and the suicide of its commanding general, Alexander Samsonov. A series of follow-up battles led to the ousting of the Russian 1st Army from East Prussia.
August 1914
Battle of Liège
The Battle of Liège was the opening engagement of the German invasion of Belgium and the first battle of the First World War. The city of Liège was protected by a ring of modern fortresses, one of several fortified cities intended to delay an invasion for troops from the powers guaranteeing Belgian neutrality to mobilise and join the Belgian Army in the expulsion of the invader.
August 1914 – September 1914
Battle of Galicia
The Battle of Galicia, also known as the Great Battle of Galicia, was a major battle between Russia and Austria-Hungary during the early stages of World War I in 1914. In the course of the battle, the Austro-Hungarian armies were severely defeated in several encounters and forced out of Galicia, while the Russians captured Lemberg and, for approximately nine months, ruled Eastern Galicia until their defeat at Gorlice and Tarnów. The Battle of Galicia showed weaknesses of the Austro-Hungarian Army during that period and at the same time was one of the formidable victories of the Imperial Russian Army in the war.
August 1914 – September 1914
Battle of the Frontiers
The Battle of the Frontiers comprised battles fought along the eastern frontier of France and in southern Belgium, shortly after the outbreak of the First World War. The battles resolved the military strategies of the French Chief of Staff General Joseph Joffre with Plan XVII and an offensive adaptation of the German Aufmarsch II deployment plan by Helmuth von Moltke the Younger. The German concentration on the right (northern) flank, was to wheel through Belgium and attack the French in the rear.
August 1914
Battle of Stallupönen
The Battle of Stallupönen, fought between Russian and German armies on August 17, 1914, was the opening battle of World War I on the Eastern Front. The Germans under the command of Hermann von François conducted a successful counterattack against four Russian infantry divisions from different infantry corps, which heavily outnumbered them but were separated from each other, creating a gap between the 27th Infantry Division and the 40th Infantry Division, and had little coordination with each other. The Germans retreated to Gumbinnen thereafter.
August 1914
Battle of Cer
The Battle of Cer was a military campaign fought between Austria-Hungary and Serbia in August 1914, starting three weeks into the Serbian Campaign of 1914, the initial military action of the First World War. It took place around Cer Mountain and several surrounding villages, as well as the town of Šabac.
August 1914
Battle of Gumbinnen
The Battle of Gumbinnen, initiated by forces of the German Empire on 20 August 1914, was a German offensive on the Eastern Front during the First World War. Because of the hastiness of the German attack, the Russian Army emerged victorious.
August 1914
Battle of Charleroi
The Battle of Charleroi or the Battle of the Sambre, was fought on 21 August 1914, by the French Fifth Army and the German 2nd and 3rd armies, during the Battle of the Frontiers. The French were planning an attack across the Sambre River, when the Germans attacked first, forced back the French from the river and nearly cut off the French retreat by crossing the Meuse River around Dinant and getting behind the French right flank. The French were saved by a counter-attack at Dinant and the re-direction of the 3rd Army to the north-west in support of the 2nd Army, rather than south-west.
August 1914
Battle of Mons
The Battle of Mons, or the First Battle of Mons to differentiate it from another battle later in the war, was the first big engagement of the British Expeditionary Force (BEF) in the First World War. It was a subsidiary action of the Battle of the Frontiers, in which the Allies clashed with the German Army on the French–German frontier. At Mons, the British Army attempted to hold the line of the Mons–Condé Canal against the advancing German 1st Army.
August 1914
Battle of Heligoland Bight (1914)
The Battle of Heligoland Bight was the first Anglo-German naval battle of the First World War, fought on 28 August 1914, between ships of the United Kingdom and Germany. The battle took place in the south-eastern North Sea, when the British attacked German patrols off the north-west German coast. The German High Seas Fleet was in harbour on the north German coast while the British Grand Fleet was out in the northern North Sea. Both sides engaged in long-distance sorties with cruisers and battlecruisers, with close reconnaissance of the area of sea near the German coast—the Heligoland Bight—by destroyer.
August 1914
Battle of the Ardennes
The Battle of the Ardennes took place during the First World War fought on the frontiers of France, Germany, Belgium and Luxembourg from 21 to 23 August 1914. The German Empire defeated the Third French Republic and forced a French retreat. The battle was part of the larger Battle of the Frontiers, the first battle of the Western Front.
August 1914
Battle of Lorraine
The Battle of Lorraine was a battle on the Western Front during the First World War. The armies of France and Germany had completed their mobilisation, the French with Plan XVII, to conduct an offensive through Lorraine and Alsace into Germany and the Germans with Aufmarsch II West, for an offensive in the north through Luxembourg and Belgium into France, supplemented with attacks in the south to prevent the French from transferring troops to the greater threat in the north.
August 1914 – October 1914
German invasion of Belgium (1914)
The German invasion of Belgium began on 4 August 1914 during the first World War. On 24 July, the Belgian government had announced that if war came it would uphold its neutrality. The Belgian government mobilised its armed forces on 31 July and a state of heightened alert was proclaimed in Germany. On 2 August, the German government sent an ultimatum to Belgium, demanding passage through the country and German forces invaded Luxembourg. Two days later, the Belgian government refused the German demands and the British government guaranteed military support to Belgium. The German government declared war on Belgium on 4 August; German troops crossed the border and began the Battle of Liège.
September 1914
First Battle of the Marne
The First Battle of the Marne or known in France as the Miracle on the Marne was a battle of the First World War fought from 5 to 12 September 1914. The German army invaded France with a plan for winning the war in 40 days by occupying Paris and destroying the French and British armies. The Germans had initial successes in August. They were victorious in the Battles of Mons and the Frontiers and overran a large area of northern France and Belgium. In what is called the Great Retreat the Germans pursued the retreating French and British forces more than 250 km (160 mi) southwards. The French and British halted their retreat in the Marne River valley, while the Germans advanced to 40 km from Paris.
September 1914
First Battle of the Masurian Lakes
The First Battle of the Masurian Lakes was a German offensive in the Eastern Front 2–16 September 1914, during the Russian invasion of East Prussia. It took place only days after the Battle of Tannenberg where the German 8th Army encircled and destroyed the Russian 2nd Army. Using the rapid movements aided by the East Prussian railway network, the 8th Army reformed in front of the spread-out Russian 1st Army and pushed it back across its entire front, eventually ejecting it from Germany. Further progress was hampered by the arrival of the Russian 10th Army on the Germans' right flank.
September 1914 – March 1915
Siege of Przemyśl
The Siege of Przemyśl was the longest siege in Europe during the First World War, and the second-longest in the entire conflict, after the Siege of Medina. The siege was a crushing defeat of the Austro-Hungarian Army by the Russian Army. Przemyśl was a fortress-town and stronghold on the River San in Austrian Galicia. The investment of Przemyśl began on 16 September 1914 and was briefly suspended on 11 October, due to an Austro-Hungarian offensive. The siege resumed on 9 November and the Austro-Hungarian garrison surrendered on 22 March 1915, after holding out for a total of 133 days. The siege has been referred to as "Austria-Hungary's Stalingrad".
September 1914 – October 1914
Siege of Antwerp (1914)
The siege of Antwerp was an engagement between the German and the Belgian, British and French armies around the fortified city of Antwerp during the First World War. German troops besieged a garrison of Belgian fortress troops, the Belgian field army and the British Royal Naval Division in the Antwerp area, after the German invasion of Belgium in August 1914. The city, which was ringed by forts known as the National Redoubt, was besieged to the south and east by German forces.
September 1914 – November 1914
Race to the Sea
The Race to the Sea took place from 17 September to 19 October 1914 during the First World War, after the Battle of the Frontiers and the German advance into France. The invasion had been stopped at the First Battle of the Marne (5–12 September) and was followed by the First Battle of the Aisne (13–28 September), a Franco-British counter-offensive. The term describes reciprocal attempts by the Franco-British and German armies to envelop the northern flank of the opposing army through the provinces of Picardy, Artois and Flanders, rather than an attempt to advance northwards to the sea. The "race" ended on the North Sea coast of Belgium around 19 October, when the last open area from Diksmuide to the North Sea was occupied by Belgian troops who had retreated after the Siege of Antwerp. The outflanking attempts had resulted in a number of encounter battles but neither side was able to gain a decisive victory.
September 1914
First Battle of the Aisne
The First Battle of the Aisne was the Allied follow-up offensive against the right wing of the German First Army and the Second Army as they retreated after the First Battle of the Marne earlier in September 1914. The Advance to the Aisne consisted of the Battle of the Marne (7–10 September) and the Battle of the Aisne (12–15 September).
October 1914 – October 1918
Caucasus campaign
The Caucasus campaign, also known as the Caucasus Front, comprised armed conflicts between the Russian Empire and the Ottoman Empire, later including Armenia, Azerbaijan, Georgia, the Mountainous Republic of the Northern Caucasus, the German Empire, the Central Caspian Dictatorship, and the British Empire, as part of the Middle Eastern theatre during World War I. The Caucasus campaign extended from the South Caucasus to the Armenian Highlands region, reaching as far as Trabzon, Bitlis, Mush and Van. The land warfare was accompanied by naval engagements in the Black Sea.
October 1914 – November 1914
First Battle of Ypres
The First Battle of Ypres was a battle of the First World War, fought on the Western Front around Ypres, in West Flanders, Belgium. The battle was part of the First Battle of Flanders, in which German, French, Belgian armies and the British Expeditionary Force (BEF) fought from Arras in France to Nieuwpoort (Nieuport) on the Belgian coast, from 10 October to mid-November. The battles at Ypres began at the end of the Race to the Sea, reciprocal attempts by the German and Franco-British armies to advance past the northern flank of their opponents. North of Ypres, the fighting continued in the Battle of the Yser (16–31 October), between the German 4th Army, the Belgian army and French marines.
October 1914
Battle of the Yser
The Battle of the Yser was a battle of the First World War that took place in October 1914 between the towns of Nieuwpoort and Diksmuide, along a 35 km (22 mi) stretch of the Yser River and the Yperlee Canal, in Belgium. The front line was held by a large Belgian force, which halted the German advance in a costly defensive battle.
November 1914 – December 1914
Battle of Kolubara
The Battle of Kolubara was fought between Austria-Hungary and Serbia in November and December 1914, during the Serbian Campaign of 1914.
November 1914 – December 1914
Battle of Łódź (1914)
The Battle of Łódź or Lodz operation took place from 11 November to 6 December 1914, near the city of Łódź in Poland. Battles were fought between German units of the 8th Army, 9th Army, Austrian 1st Army, and the Russian 1st, 2nd, and 5th Armies, in harsh winter conditions. The Germans redeployed their 9th Army around Thorn, so as to threaten the Russian northern flank, following German reversals after the Battle of the Vistula River. The German objective was to prevent an invasion of Germany, by encircling and destroying the Russians; instead, the Germans were surrounded and lost two corps; still, the invasion of Germany was prevented. The battle had a strong impact on both the Western and Eastern fronts. It ended with the tactical victory of the Russian troops, although the Russians eventually withdrew and the pressure on the Austrians eased, as reinforcements that could have gone to Przemyśl went instead to Łódź; implying a strategic victory for Germany.
December 1914 – January 1915
Battle of Sarikamish
The Battle of Sarikamish was an engagement between the Russian and Ottoman Empires during World War I. It took place from 22 December 1914, to 17 January 1915, as part of the Caucasus campaign.
December 1914 – March 1915
First Battle of Champagne
The First Battle of Champagne was fought from 20 December 1914 – 17 March 1915 in World War I in the Champagne region of France and was the second offensive by the Allies against the German Empire since mobile warfare had ended after the First Battle of Ypres in Flanders (19 October – 22 November 1914). The battle was fought by the French Fourth Army and the German 3rd Army. The offensive was part of a French strategy to attack the Noyon Salient, a large bulge in the new Western Front, which ran from Switzerland to the North Sea. The First Battle of Artois began on the northern flank of the salient on 17 December and the offensive against the southern flank in Champagne began three days later.
January 1915
Battle of Dogger Bank (1915)
The Battle of Dogger Bank was a naval engagement during the First World War near the Dogger Bank in the North Sea, between squadrons of the British Grand Fleet and the Kaiserliche Marine. The British had intercepted and decoded German wireless transmissions, gaining advance knowledge that a German raiding squadron was heading for the Dogger Bank. Ships of the Grand Fleet sailed to intercept the raiders.
February 1915 – January 1916
Gallipoli campaign
The Gallipoli campaign, the Dardanelles campaign, the Defence of Gallipoli or the Battle of Gallipoli was a military campaign in the First World War on the Gallipoli Peninsula from 19 February 1915 to 9 January 1916. The Allied powers unsuccessfully attempted to make the Ottoman Empire, one of the Central Powers, capitulate by taking control of the Turkish straits. They intended to expose the Ottoman capital at Constantinople to bombardment by Allied warships and cut it off from the Asian part of the empire. An Ottoman Empire defeat could have led to unfettered Western control of the Suez Canal and the opening of the Bosphorus and Dardanelles straits to Allied supplies headed for the Black Sea and warm-water ports in Russia.
February 1915
Second Battle of the Masurian Lakes
The Second Battle of the Masurian Lakes or Winter Battle of the Masurian Lakes, known in Germany as the Winter Battle in Masuria and in Russia as the Battle of Augustowo, was the northern part of the Central Powers' offensive on the Eastern Front in the winter of 1915 during World War I. The offensive was intended to advance beyond the Vistula River and potentially knock Russia out of the war. It was the last major battle fought on German soil during World War I.
April 1915 – May 1915
Second Battle of Ypres
The Second Battle of Ypres was fought from 22 April to 25 May 1915, during the First World War, for control of the tactically valuable high ground to the east and the south of the Flemish town of Ypres, in western Belgium. The First Battle of Ypres had been fought the previous autumn. The Second Battle of Ypres was the occasion of the first mass use by Germany of poison gas on the Western Front.
April 1915 – May 1915
Defense of Van (1915)
The defense of Van and in Russian Van operation was the armed resistance of the Armenian population of Van and Russian army against the Ottoman Empire's attempts to massacre the Ottoman Armenian population of the Van Vilayet in the 1915 Armenian genocide. Several contemporaneous observers and later historians have concluded that the Ottoman government deliberately instigated an armed Armenian resistance in the city and then used this insurgency as the main pretext to justify beginning the deportation and slaughter of Armenians throughout the empire. Witness reports agree that the Armenian posture at Van was defensive and an act of resistance to massacre. The self-defense action is frequently cited in Armenian genocide denial literature; it has become "the alpha and omega of the plea of 'military necessity'" to excuse the genocide and portray the persecution of Armenians as justified.
May 1915
Gorlice–Tarnów offensive
The Gorlice–Tarnów offensive during World War I was initially conceived as a minor German offensive to relieve Russian pressure on the Austro-Hungarians to their south on the Eastern Front, but resulted in the Central Powers' chief offensive effort of 1915, causing the total collapse of the Russian lines and their retreat far into Russia. The continued series of actions lasted the majority of the campaigning season for 1915, starting in early May and only ending due to bad weather in October.
June 1915 – November 1917
Battles of the Isonzo
The Battles of the Isonzo were a series of twelve battles between the Austro-Hungarian and Italian armies in World War I mostly on the territory of present-day Slovenia, and the remainder in Italy along the Isonzo River on the eastern sector of the Italian Front between June 1915 and November 1917.
June 1915 – July 1915
First Battle of the Isonzo
The First Battle of the Isonzo was fought between the armies of Italy and Austria-Hungary on the northeastern Italian Front in World War I, between 23 June and 7 July 1915.
July 1915 – August 1915
Second Battle of the Isonzo
The Second Battle of the Isonzo was fought between the armies of the Kingdom of Italy and those of Austria-Hungary in the Italian Front in World War I, between 18 July and 3 August 1915.
September 1915 – October 1915
Battle of Loos
The Battle of Loos took place from 25 September to 8 October 1915 in France on the Western Front, during the First World War. It was the biggest British attack of 1915, the first time that the British used gas as a weapon and the first mass engagement of New Army divisions. The French and British tried to break through the German defences in Artois in the north and Champagne at the south end of the Noyon Salient, to restore a war of movement.
December 1915 – April 1916
Siege of Kut
The siege of Kut Al Amara, also known as the first battle of Kut, was the besieging of an 8,000-strong British Indian Army garrison in the town of Kut, 160 km (100 mi) south of Baghdad, by the Ottoman Army. In 1915, its population was around 6,500. Following the surrender of the garrison on 29 April 1916, the survivors of the siege were marched to imprisonment at Aleppo, during which many died. Historian Christopher Catherwood has called the siege "the worst defeat of the Allies in World War I". Ten months later, the British Indian Army, consisting almost entirely of newly recruited troops from Western India, conquered Kut, Baghdad and other regions in between in the fall of Baghdad.
January 1916 – February 1916
Erzurum offensive
The Erzurum offensive or Battle of Erzurum was a major winter offensive by the Imperial Russian Army on the Caucasus Campaign, during the First World War that led to the capture of the strategic city of Erzurum. The Turkish forces, in winter quarters, suffered a series of unexpected reverses, which led to a Russian victory.
February 1916 – December 1916
Battle of Verdun
The Battle of Verdun was fought from 21 February to 18 December 1916 on the Western Front in France. The battle was the longest of the First World War and took place on the hills north of Verdun. The German 5th Army attacked the defences of the Fortified Region of Verdun and those of the French Second Army on the right (east) bank of the Meuse. Using the experience of the Second Battle of Champagne in 1915, the Germans planned to capture the Meuse Heights, an excellent defensive position, with good observation for artillery-fire on Verdun. The Germans hoped that the French would commit their strategic reserve to recapture the position and suffer catastrophic losses at little cost to the German infantry.
March 1916 – April 1916
Lake Naroch offensive
The Lake Naroch offensive in 1916 was an unsuccessful Russian offensive on the Eastern Front in World War I. It was launched at the request of Marshal Joseph Joffre and intended to relieve the German pressure on French forces. Due to lack of reconnaissance, Russian artillery support failed to overcome and neutralise the well-fortified German defenses and artillery positions, leading to costly and unproductive direct attacks, hindered by the weather. On 30 March General Evert ordered a halt to the offensive.
May 1916 – June 1916
Battle of Jutland
The Battle of Jutland was a naval battle between Britain's Royal Navy Grand Fleet, under Admiral Sir John Jellicoe, and the Imperial German Navy's High Seas Fleet, under Vice-Admiral Reinhard Scheer, during the First World War. The battle unfolded in extensive manoeuvring and three main engagements from 31 May to 1 June 1916, off the North Sea coast of Denmark's Jutland Peninsula. It was the largest naval battle and only full-scale clash of battleships of the war. Jutland was also the last major naval battle, in any war, fought primarily by battleships.
May 1916 – June 1916
Battle of Asiago
The Battle of Asiago, also known as Südtirol Offensive or Battle of the Plateaux, wrongly nicknamed Strafexpedition, began with a major offensive launched on 15 May 1916 by the Austro-Hungarians on the territory of Vicentine Alps in the Italian Front of World War I. It was an "unexpected" attack that took place in the Asiago plateau after the Fifth Battle of the Isonzo. The Austro-Hungarian offensive, initially successful, was followed by an Italian counter-offensive reconquering much of the lost ground and Asiago.
July 1916 – November 1916
Battle of the Somme
The Battle of the Somme, also known as the Somme offensive, was a battle of the First World War fought by the armies of the British Empire and the French Republic against the German Empire. It took place between 1 July and 18 November 1916 on both sides of the upper reaches of the river Somme in France. The battle was intended to hasten a victory for the Allies. More than three million men fought in the battle, of whom more than one million were either wounded or killed, making it one of the deadliest battles in human history. It illustrated the deadly potential of mechanized warfare that began in the mid-19th century.
August 1916 – November 1916
Battle of Transylvania
The Battle of Transylvania was the first major operation of Romania during World War I, beginning on 27 August 1916. It started as an attempt by the Romanian Army to seize Transylvania, and potentially knock Austria-Hungary out of the war. Although initially successful, the offensive was brought to a halt after Bulgaria's attack on Dobruja. Coupled with a successful German and Austro-Hungarian counterattack which started in mid-September, the Romanian Army was eventually forced to retreat back to the Carpathians by mid-October. The Romanian armies however managed to escape the Central Powers' attempts to completely destroy them. The Battle of Transylvania also caused the replacement of the chief of staff of the German Army and the shifting of German attention to the region, causing German offensive operations at Verdun to cease.
March 1917
First Battle of Gaza
The First Battle of Gaza was fought on 26 March 1917 during the first attempt by the Egyptian Expeditionary Force (EEF), which was a British Empire military formation, formed on 10 March 1916 under the command of General Archibald Murray from the Mediterranean Expeditionary Force and the Force in Egypt (1914–15), at the beginning of the Sinai and Palestine Campaign of the First World War. Fighting took place in and around the town of Gaza on the Mediterranean coast when infantry and mounted infantry from the Desert Column, a component of the Eastern Force, attacked the town. Late in the afternoon, on the verge of capturing Gaza, the Desert Column was withdrawn due to concerns about the approaching darkness and large Ottoman reinforcements. This British defeat was followed a few weeks later by the even more emphatic defeat of the Eastern Force at the Second Battle of Gaza in April 1917.
April 1917
Battle of Vimy Ridge
The Battle of Vimy Ridge was part of the Battle of Arras, in the Pas-de-Calais department of France, during the First World War. The main combatants were the four divisions of the Canadian Corps in the First Army, against three divisions of the German 6th Army. The battle began the Battle of Arras and was the first attack of the Nivelle Offensive. The objective was to draw German reserves away from the French forces, preparing for the French offensive along the Aisne and the Chemin des Dames ridge several days later.
April 1917 – May 1917
Battle of Arras (1917)
The Battle of Arras, also known as the Second Battle of Arras, was a British offensive on the Western Front during the First World War. From 9 April to 16 May 1917, British troops attacked German defences near the French city of Arras on the Western Front. The British achieved the longest advance since trench warfare had begun, surpassing the record set by the French Sixth Army on 1 July 1916 in the First day on the Somme. The British advance slowed in the next few days and the German defence recovered. The battle became a costly stalemate for both sides and by the end of the battle, the British Third Army and the First Army had suffered about 160,000 casualties and the German 6th Army about 125,000.
April 1917 – May 1917
Nivelle offensive
The Nivelle offensive was a Franco-British operation on the Western Front in the First World War that led to mutinies in the French Army. The offensive was named after General Robert Nivelle, the commander-in-chief of the French metropolitan armies. The French part of the offensive was intended to be decisive by breaking through the German defences on the Aisne front within 48 hours, with casualties expected to be around 10,000 men. A preliminary attack was to be made by the French Third Army at St Quentin and the British First, Third and Fifth armies at Arras, to capture high ground and divert German reserves from the French on the Aisne and in Champagne. The main offensive was to be delivered by the French on the Chemin des Dames ridge. A subsidiary attack was to be made by the Fourth Army. The final stage of the offensive was to follow the meeting of the British and French armies, having broken through the German lines, to pursue the defeated German armies towards the German frontier.
April 1917 – May 1917
Second Battle of the Aisne
The Second Battle of the Aisne was the main part of the Nivelle Offensive, a Franco-British attempt to inflict a decisive defeat on the German armies in France. The Entente strategy was to conduct offensives from north to south, beginning with an attack by the British Expeditionary Force (BEF) then the main attack by two French army groups on the Aisne. General Robert Nivelle planned the offensive in December 1916, after he replaced Joseph Joffre as Commander-in-Chief of the French Army.
June 1917
Battle of Messines (1917)
The Battle of Messines was an attack by the British Second Army, on the Western Front, near the village of Messines in West Flanders, Belgium, during the First World War. The Nivelle Offensive in April and May had failed to achieve its more grandiose aims, had led to the demoralisation of French troops and confounded the Anglo-French strategy for 1917.
July 1917 – November 1917
Battle of Passchendaele
The Third Battle of Ypres, also known as the Battle of Passchendaele, was a campaign of the First World War, fought by the Allies against the German Empire. The battle took place on the Western Front, from July to November 1917, for control of the ridges south and east of the Belgian city of Ypres in West Flanders, as part of a strategy decided by the Entente at conferences in November 1916 and May 1917. Passchendaele lies on the last ridge east of Ypres, 5 mi (8 km) from Roulers, a junction of the Bruges-(Brugge)-to-Kortrijk railway. The station at Roulers was on the main supply route of the German 4th Army. Once Passchendaele Ridge had been captured, the Allied advance was to continue to a line from Thourout to Couckelaere (Koekelare).
September 1917 – October 1917
Operation Albion
Operation Albion was a German air, land and naval operation in the First World War, against Russian forces in October 1917 to occupy the West Estonian Archipelago. The campaign aimed to occupy the Baltic islands of Saaremaa (Ösel), Hiiumaa (Dagö) and Muhu (Moon). The three islands were part of the Russian Empire and strategically dominated the central and northern Baltic Sea. The land campaign opened with German landings at the Tagalaht (Tagga) bay on the island of Saaremaa (Ösel), on 12 October, after extensive naval operations to clear mines and subdue coastal artillery batteries. German forces secured the island by 16 October and the Russian army evacuated Muhu (Moon) on 20 October.
October 1917 – November 1917
Battle of Caporetto
The Battle of Caporetto took place on the Isonzo front of World War I.
November 1917 – December 1917
Battle of Cambrai (1917)
The Battle of Cambrai was a British attack in the First World War, followed by the biggest German counter-attack against the British Expeditionary Force (BEF) since 1914. The town of Cambrai, in the département of Nord, in France, was an important supply centre for the German Siegfriedstellung and capture of the town and the nearby Bourlon Ridge would threaten the rear of the German line to the north. Major General Henry Tudor, Commander, Royal Artillery (CRA), of the 9th (Scottish) Division, advocated the use of new artillery-infantry tactics on his sector of the front. During preparations, J. F. C. Fuller, a staff officer with the Tank Corps, looked for places to use tanks for raids. General Julian Byng, commander of the Third Army, decided to combine both plans. The French and British armies had used tanks en masse earlier in 1917, although to considerably less effect.
November 1917 – December 1917
Battle of Jerusalem
The Battle of Jerusalem also known as the Fall of Jerusalem occurred during the British Empire's "Jerusalem Operations" against the Ottoman Empire, in World War I, when fighting for the city developed from 17 November, continuing after the surrender until 30 December 1917, to secure the final objective of the Southern Palestine Offensive during the Sinai and Palestine Campaign of World War I. Before Jerusalem could be secured, two battles were recognised by the British as being fought in the Hebron Hills to the north and east of the Hebron–Junction Station line. These were the Battle of Nebi Samwill from 17 to 24 November and the Defence of Jerusalem from 26 to 30 December 1917. They also recognised within these Jerusalem Operations, the successful second attempt on 21 and 22 December 1917 to advance across the Nahr el Auja, as the Battle of Jaffa, although Jaffa had been occupied as a consequence of the Battle of Mughar Ridge on 16 November.
March 1918 – July 1918
German spring offensive
The German spring offensive, also known as Kaiserschlacht or the Ludendorff offensive, was a series of German attacks along the Western Front during the First World War, beginning on 21 March 1918. Following the American entry into the war in April 1917, the Germans decided that their only remaining chance of victory was to defeat the Allies before the United States could ship soldiers across the Atlantic and fully deploy its resources. The Imperial German Army had gained a temporary advantage in numbers as nearly 50 divisions had been freed by the Russian withdrawal from the war with the Treaty of Brest-Litovsk.
March 1918 – April 1918
Operation Michael
Operation Michael was a major German military offensive during World War I that began the German spring offensive on 21 March 1918. It was launched from the Hindenburg Line, in the vicinity of Saint-Quentin, France. Its goal was to break through the Allied (Entente) lines and advance in a north-westerly direction to seize the Channel Ports, which supplied the British Expeditionary Force (BEF), and to drive the BEF into the sea, all before the Americans could arrive in full numbers to turn the tide of the war. Two days later, General Erich Ludendorff, the chief of the German General Staff, adjusted his plan and pushed for an offensive due west, along the whole of the British front north of the River Somme. This was designed to first separate the French and British Armies before continuing with the original concept of pushing the BEF into the sea. The offensive ended at Villers-Bretonneux, to the east of the Allied communications centre at Amiens, where the Allies managed to halt the German advance; the German Army had suffered many casualties and was unable to maintain supplies to the advancing troops.
May 1918 – August 1918
Second Battle of the Marne
The Second Battle of the Marne was the last major German offensive on the Western Front during the First World War. The attack failed when an Allied counterattack, led by French forces and supported by several hundred Renault FT tanks, overwhelmed the Germans on their right flank, inflicting severe casualties. The German defeat marked the start of the relentless Allied advance which culminated in an armistice with Germany about 100 days later.
May 1918
Battle of Sardarabad
The Battle of Sardarabad was a battle of the Caucasus campaign of World War I that took place near Sardarabad, Armenia, from 21 to 29 May 1918, between the regular Armenian military units and militia on one side and the Ottoman army that had invaded Eastern Armenia on the other. As Sardarabad is approximately 40 kilometres (25 mi) west of the capital of Yerevan, the battle not only halted the Ottoman advance into the rest of Armenia, but also prevented the complete destruction of the Armenian nation. The battle paved the way for the establishment of the First Republic of Armenia and the Treaty of Batum: recognition of Armenia by the Ottoman Empire.
May 1918
Battle of Abaran
The Battle of Bash Abaran was part of Caucasus Campaign of World War I that took place in the vicinity of Bash Abaran, in 1918. The Armenian victories at Bash Abaran, Sardarabad and Karakilisa, halted the Ottoman invasion of Eastern Armenia and were instrumental in allowing the formation of the short-lived First Republic of Armenia.
May 1918 – June 1918
Third Battle of the Aisne
The Third Battle of the Aisne was part of the German spring offensive during World War I that focused on capturing the Chemin des Dames Ridge before the American Expeditionary Forces arrived completely in France. It was one of a series of offensives, known as the Kaiserschlacht, launched by the Germans in the spring and summer of 1918.
June 1918
Second Battle of the Piave River
The Second Battle of the Piave River, fought between 15 and 23 June 1918, was a decisive victory for the Italian Army against the Austro-Hungarian Empire during World War I, as Italy was part of the Allied Forces, while Austria-Hungary was part of the Central Powers. Though the battle proved to be a decisive blow to the Austro-Hungarian Empire and by extension the Central Powers, its full significance was not initially appreciated in Italy. Yet Erich Ludendorff, on hearing the news, is reported to have said he 'had the sensation of defeat for the first time'. It would later become clear that the battle was in fact the beginning of the end of the Austro-Hungarian Empire.
June 1918
Battle of Belleau Wood
The Battle of Belleau Wood was a major battle that occurred during the German spring offensive in World War I, near the Marne River in France. The battle was fought by the U.S. 2nd and 3rd Divisions along with French and British forces against an assortment of German units including elements from the 237th, 10th, 197th, 87th, and 28th Divisions.
August 1918 – November 1918
Hundred Days Offensive
The Hundred Days Offensive was a series of massive Allied offensives that ended the First World War. Beginning with the Battle of Amiens on the Western Front, the Allies pushed the Imperial German Army back, undoing its gains from the German spring offensive.
August 1918
Battle of Amiens (1918)
The Battle of Amiens, also known as the Third Battle of Picardy, was the opening phase of the Allied offensive which began on 8 August 1918, later known as the Hundred Days Offensive, which ultimately led to the end of World War I. Allied forces advanced over 11 kilometres (7 mi) on the first day, one of the greatest advances of the war, with Gen Henry Rawlinson's British Fourth Army, with nine of its 19 divisions supplied by the fast-moving Australian Corps of Lt General John Monash and Canadian Corps of Lt General Arthur Currie, and Gen Marie Eugène Debeney's French First Army playing a decisive role. The battle is also notable for its effects on both sides' morale and the large number of surrendering German forces. This led Erich Ludendorff to later describe the first day of the battle as "the black day of the German Army". Amiens was one of the first major battles involving armoured warfare.
August 1918 – September 1918
Battle of Baku
The Battle of Baku took place in August and September 1918 between the Ottoman–Azerbaijani coalition forces led by Nuri Pasha and Bolshevik–ARF Baku Soviet forces, later succeeded by the British–Armenian–White Russian forces led by Lionel Dunsterville, and saw Soviet Russia briefly re-enter the war. The battle took place during World War I, was a conclusive part of the Caucasus Campaign, but a beginning of the Armenian–Azerbaijani War.
September 1918 – November 1918
Meuse–Argonne offensive
The Meuse–Argonne offensive was a major part of the final Allied offensive of World War I that stretched along the entire Western Front. It was fought from September 26, 1918, until the Armistice of November 11, 1918, a total of 47 days. The Meuse–Argonne offensive was the largest in United States military history, involving 1.2 million American soldiers, sailors and marines, along with 800,000 French and 850 Siamese personnel. It is also the deadliest campaign in the history of the United States Army, resulting in over 300,000 casualties, including 28,000 German lives, 26,277 American lives and about 35,000 French lives. American losses were worsened by the inexperience of many of the troops, the tactics used during the early phases of the operation, and the widespread onset of the Spanish flu.
September 1918
Battle of Dobro Pole
The Battle of Dobro Pole, also known as the Breakthrough at Dobro Pole, was a World War I battle fought between 15 and 18 September 1918. The battle was fought in the initial stage of the Vardar offensive, in the Balkan Front. On 15 September, a combined force of Serbian, French and Greek troops attacked the Bulgarian-held trenches in Dobro Pole, at the time part of the Bulgarian-occupied Kingdom of Serbia and the Kingdom of Greece. The offensive and the preceding artillery preparation had devastating effects on Bulgarian morale, eventually leading to mass desertions.
September 1918
Battle of Megiddo (1918)
The Battle of Megiddo was fought between 19 and 25 September 1918, on the Plain of Sharon, in front of Tulkarm, Tabsor and Arara in the Judean Hills as well as on the Esdralon Plain at Nazareth, Afulah, Beisan, Jenin and Samakh. Its name, which has been described as "perhaps misleading" since very limited fighting took place near Tel Megiddo, was chosen by British commander Edmund Allenby for its biblical and symbolic resonance.
October 1918 – November 1918
Battle of Vittorio Veneto
The Battle of Vittorio Veneto was fought from 24 October to 4 November 1918 near Vittorio Veneto on the Italian Front during World War I. After having defeated Austro-Hungarian troops during the Second Battle of the Piave River and recognizing the dire internal situation of Austria-Hungary caused by the course of the war and the blockade of the Adriatic at sea, the Royal Italian Army launched a major offensive: the Italian victory marked the end of the war on the Italian Front and the dissolution of the Austro-Hungarian Empire, contributing to the end of the First World War just one week later. The battle led to the capture of over 5,000 artillery pieces and 448,000 Austro-Hungarian troops, including Germans, Hungarians, Czechs, Slovaks, Slovenes, Croatians, Poles, Romanians, Ukrainians, and also a small number of Austro-Hungarian Italians.
