1. Lead

The Meuse-Argonne Offensive, fought from 26 September to 11 November 1918, was the largest battle in American history, and the battle that ended the First World War. About 1,200,000 American soldiers — the American Expeditionary Forces, under General John J. Pershing — attacked the German armies between the Meuse River and the Argonne Forest, in north-eastern France, in a 47-day offensive that drove the Germans back, broke their last defensive lines, and forced Germany to sue for an armistice. The offensive cost the Americans about 122,000 casualties, including 26,277 killed, and it cost the Germans about 100,000 to 126,000 men, and it was the greatest American battle ever fought, in men, in guns, and in lives lost.

The Meuse-Argonne is remembered in the United States as the battle that made the American Army, and as the battle that ended the war. It is remembered for the Lost Battalion, the 554 men of the 308th Infantry Regiment who were surrounded in the Argonne Forest and held out for five days; for Sergeant Alvin York, who single-handedly captured 132 German soldiers; and for the sheer scale of the American effort — 1,200,000 men, 2,780 guns, 800 aircraft — in a battle that was fought in the mud and the rain of the autumn of 1918, and that ended, on 11 November, with the Armistice and the silence of the guns.

3. Background

3.1. The Strategic Background

By the autumn of 1918, the First World War was in its final months. The German spring offensives of 1918, which had come close to winning the war, had failed, and the Allies, reinforced by the Americans, had gone on the offensive in the summer, in the Hundred Days Offensive, driving the Germans back along the whole Western Front. The American Expeditionary Forces, under General John J. Pershing, had fought at Cantigny, at Belleau Wood, at Château-Thierry and at Saint-Mihiel, and they had grown from a small force into an army of more than a million men. Pershing, who had insisted that the Americans fight as an independent army, under American command, and not as reinforcements for the French and British, was given the sector between the Meuse River and the Argonne Forest, and ordered to attack there, in coordination with the French Fourth Army to the west, as part of the great Allied offensive that would end the war.

Supply decided more of Meuse-Argonne Offensive than any single order. Ammunition, fuel, food and water had to travel from depots far behind the lines, over roads that were shelled, mined or washed out, and every delay at the front was felt first in the supply columns. The side that kept its guns fed and its men fed could keep attacking; the side that could not was forced to stop, however good its plan. At Meuse-Argonne Offensive, as in most battles of this period, the quartermasters and the drivers mattered as much as the generals, and the battle’s turning points can often be traced to a convoy that arrived — or did not arrive — in time.

3.2. The Opposing Plans

The German defences in the Meuse-Argonne were formidable. The Germans had held the ground since 1914, and they had fortified it in depth: the Hindenburg Line, the great German defensive system, ran through the sector, with three lines of trenches, barbed wire, concrete pillboxes and artillery, and behind it the Kriemhilde Stellung, the strongest part of the line, which ran across the heights of the Argonne and the Meuse. The Argonne Forest itself was a dense, tangled wood, cut by ravines and streams, and the Meuse River, to the east, was a barrier that the Americans had to cross. The Germans, under General Max von Gallwitz, commander of the Fifth Army, had about 450,000 men in the sector, and they were ordered to hold it at all costs, because behind it lay the German railway network — the lines through Sedan and Mézières — on which the whole German Army in France depended for its supplies.

Neither side at Meuse-Argonne Offensive knew as much about the enemy as its commanders pretended. Reports were late, contradictory or simply wrong: prisoners exaggerated, scouts saw only a fragment of the front, and aerial photographs showed positions that had already been abandoned. Commanders filled the gaps with assumptions, and those assumptions decided battles. The history of Meuse-Argonne Offensive is full of such judgements — an enemy division believed to be elsewhere, a flank thought secure, a strength underestimated by half — and the side whose assumptions were closest to the truth usually won, not because its generals were cleverer, but because its information was better.

3.3. The Eve of Battle

The American plan was drawn up by Pershing and his staff, and it called for a frontal attack by the First Army, with three corps abreast, on a front of about 30 kilometres, from the Meuse in the east to the Argonne in the west. The attack was to be made on 26 September 1918, after a three-hour artillery preparation by 2,780 guns, the largest American bombardment of the war, and it was to be supported by 800 aircraft, the largest American air force ever assembled, and by 189 tanks, mostly French Renaults with American crews. The plan was ambitious, and it was made in haste: the Americans had only two weeks to prepare, the troops had to march to the front at night, in the rain, and the artillery had to be moved into position in the dark. The attack was the largest American operation of the war, and it was the test of whether the American Army, which had been built in eighteen months, could fight a great battle.

Orders at Meuse-Argonne Offensive travelled slowly and unreliably. Field telephones depended on wires that shellfire cut within minutes; radios were heavy, short-ranged and easily intercepted; and in the end much depended on runners — men who carried written orders across open ground under fire, and who sometimes never arrived. A battalion could fight for hours without knowing what its neighbours were doing, and a division could learn of a breakthrough only when the enemy appeared in its rear. The battle therefore has to be understood as a dozen small battles fought in partial ignorance of each other, held together by a command system that was always one step behind events.

3.3.1. The Wider War

The wider war shaped everything that happened at Meuse-Argonne Offensive. By the time the fighting began, the conflict had already lasted for years, and both sides had learned hard lessons about supply, firepower and morale. Commanders on both sides knew that a single battle rarely decided a war, but that battles like this one decided whether armies could move, eat and fight the next week. For the men who fought here, the strategic arguments debated in headquarters meant very little beside the next hill, the next street or the next stretch of water. What mattered was whether the artillery was in range, whether the rations arrived, and whether the unit on the flank held its ground. The records of Meuse-Argonne Offensive therefore have to be read on two levels at once: as a chapter in a much larger war, and as a human experience of fear, exhaustion and endurance that no headquarters map can capture.

4. Opposing Forces

4.1. The Attacking Force and the German Defence

The American forces in the Meuse-Argonne were the First Army, under General John J. Pershing, with about 1,200,000 men in three corps — the I, III and V Corps — together with the French Fourth Army on the left, under General Henri Gouraud, and the French Second Army on the right, under General Hirschauer. The American divisions were a mixture of Regular Army, National Guard and National Army divisions, many of them inexperienced, and the First Army was supported by 2,780 guns, 800 aircraft and 189 tanks. The American strength was numbers and firepower, and the morale of men who believed they were fighting to end the war. The American weakness was inexperience: many of the divisions had never fought a major battle, and the staff work — the supply, the communications, the coordination of artillery and infantry — was often confused, especially in the first days of the offensive.

The German forces were the Fifth Army, under General Max von Gallwitz, part of the Army Group of Crown Prince Wilhelm, with about 450,000 men in the sector, in divisions that had been fighting for four years and that were well trained, well equipped, and fighting on ground they knew. The Germans had the advantage of the defence: the Hindenburg Line, the Kriemhilde Stellung, the Argonne Forest and the Meuse River, and the artillery that was sited to fire on the American advance. But the Germans were outnumbered, their divisions were understrength, their supplies were short, and their morale was breaking: the German Army, which had lost a million men in 1918, was retreating all along the front, and the soldiers, who knew the war was lost, were deserting in growing numbers.

The ground at Meuse-Argonne Offensive rewarded the side that studied it. A ridge, a river, a wood or a ruined village could be worth a battalion, and commanders who had walked the ground — or who listened to the men who had — gained advantages that no map could give. The fighting followed the ground: attacks went where the ground allowed them, defences were built where the ground was strong, and the deadliest places in the battle were the places where the ground gave one side a clear field of fire and the other no cover at all. To read the battle without the map is to miss half of it.

4.2. The Defenders and Their Methods

The balance of forces favoured the Americans in numbers and in firepower, but the battle was not decided by numbers. The Germans, in their fortified positions, could hold off a much larger force, and the Americans, who were inexperienced and who had to attack through difficult ground, paid a heavy price for every kilometre they gained. The American artillery, though numerous, was often badly coordinated, and the infantry, which advanced without adequate artillery support, was cut down by German machine guns. The battle became a slogging match, fought in the mud and the rain, in the woods and the ravines, and the Americans won it by weight of numbers and by the refusal of their men to stop, even when the cost was terrible.

The weapons used at Meuse-Argonne Offensive shaped the fighting in ways that the men who carried them understood better than their generals. A rifle that jammed in mud, a machine gun that could sweep a street, a tank that could not climb a slope, an artillery piece that could be heard but not seen — each weapon had its range, its rate of fire and its weakness, and battles were won by the side that matched its weapons to the ground. The technical details matter: the calibre of a gun, the thickness of a tank’s armour, the range of a radio. They are not footnotes to the battle; they are the reason the battle took the shape it did.

4.2.1. Guns, Engineers and Supply

Beyond the divisions listed in the table, the battle was decided by the less visible arms: the artillery that fired the preparatory bombardments, the engineers who cleared mines and built bridges, the signals units that kept commanders in touch with their forward troops, and the supply columns that brought forward ammunition, fuel, food and water. At Meuse-Argonne Offensive, as in most battles of this period, the side that could keep its guns supplied and its wounded evacuated had a decisive advantage, and the side whose communications broke down first usually lost the initiative. Air power mattered too, though not always in the way planners hoped: aircraft could strike a strongpoint or a column on the road, but they could not hold ground, and bad weather could ground them for days at a time. The balance of forces was therefore never simply a count of men and tanks; it was a balance of systems, and the system that broke first decided the outcome.

5. The Battle

5.1. The Opening Moves

The offensive began on 26 September 1918, at 05:30, after a three-hour artillery preparation by 2,780 guns, the largest American bombardment of the war. The American infantry attacked on a front of about 30 kilometres, from the Meuse in the east to the Argonne in the west, and in the first days they advanced rapidly: the German first line was overrun, the town of Montfaucon — the key to the German defences, on a high hill in the centre of the front — was taken on 27 September, after a hard fight, and the Americans advanced about 10 kilometres in the first week. But the advance then stalled: the German second line, the Kriemhilde Stellung, held, the Argonne Forest, on the left, became a maze of machine-gun nests and snipers, and the American supply system, which had to move men and guns through the mud and the rain, broke down. The offensive, which Pershing had hoped would break through in days, became a slogging match that would last 47 days.

Morale at Meuse-Argonne Offensive was not a slogan but a physical fact. Men who had eaten, slept and believed in their officers fought differently from men who were hungry, exhausted and leaderless, and the same unit could be brave on one day and broken on the next. Fear was universal — veterans admitted it freely — and what kept men fighting was rarely hatred of the enemy but loyalty to the men beside them, the shame of running, and the simple habit of obeying orders. The battle’s histories often describe morale as if it were a quality of armies; at Meuse-Argonne Offensive it was a quality of small groups of men, and it could collapse in a single afternoon.

5.2. The Main Assault

The most famous episode of the battle was the Lost Battalion, in the Argonne Forest. On 2 October 1918, nine companies of the 308th Infantry Regiment, 77th Division — about 554 men, under Major Charles Whittlesey — advanced into the Argonne Forest and were surrounded by the Germans, cut off from their division, and left without food, water or medical supplies. For five days, from 2 to 7 October, the Lost Battalion held its position in a ravine, under constant attack, and sent messages by carrier pigeon — the most famous of which, from the pigeon Cher Ami, which was wounded but delivered its message, saved the battalion from being shelled by its own artillery. On 7 October, American troops broke through to the battalion, and of the 554 men who had gone in, only 194 walked out. The Lost Battalion became a legend, and Whittlesey, who was awarded the Medal of Honor, became a national hero — though he never recovered from the experience, and killed himself in 1921.

The wounded of Meuse-Argonne Offensive depended on a chain of care that began with the man beside them. Stretcher-bearers carried them from the firing line, often under fire; aid stations, in a cellar, a ditch or a ruined house, gave them morphine and bandages; and if the roads allowed, they were evacuated to field hospitals and then further back. Many died of wounds that a modern hospital would have treated, and many lived because a comrade reached them in time. The medical story of the battle is inseparable from its casualty figures: the difference between killed and wounded, and between wounded and dead of wounds, is a measure of how well that chain worked.

5.3. The Crisis

The offensive was renewed in October, after Pershing reorganised his command: Hunter Liggett took command of the First Army, and Robert Bullard took command of the new Second Army, and the Americans, with fresh divisions and better coordination, attacked again. On 14 October, the Americans broke through the Kriemhilde Stellung, and on 1 November, after a great artillery preparation, they attacked again, in the final phase of the offensive, and broke through the German lines. The Americans crossed the Meuse, took the heights of the Meuse, and advanced towards Sedan, the railway centre on which the German Army depended. On 11 November 1918, the Armistice was signed, and the guns fell silent. The Meuse-Argonne Offensive was over, and the First World War was over with it.

Civilians were caught in Meuse-Argonne Offensive in ways that the military histories often pass over. Farmers, shopkeepers, children and the old found their villages turned into battlefields, their houses into strongpoints, their fields into minefields. Some fled, some hid in cellars, and some were killed by shells fired at targets they could not see. Their losses are the hardest to count, because no army kept their names, and their suffering is the part of the battle that has no memorial. Any honest account of Meuse-Argonne Offensive must remember that the battle was fought not on empty ground but in places where people lived, and that those people paid for it.

5.3.1. The Soldier’s Battle

For the soldiers, the battle was experienced in fragments: a long march or a cramped landing craft, a sudden burst of fire, hours of waiting under shelling, a short rush across open ground, and then the work of digging in again. Orders from above arrived late or not at all, and junior officers and sergeants made the decisions that mattered, often with only a sketchy idea of what was happening a kilometre away. Communications were fragile — field telephones cut by shellfire, radios that failed in wet weather, runners who never arrived — and the picture in each headquarters was always hours behind the fighting. That is why the history of Meuse-Argonne Offensive is written from many small accounts: a company diary, a pilot’s report, a surgeon’s notes, a prisoner’s interrogation. No single source sees the whole battle, and the historian’s task is to fit the fragments together without inventing the missing pieces.

6. Turning Point

6.1. The Decisive Moment

The turning point of the offensive was the breakthrough of the Kriemhilde Stellung on 14 October, and the renewal of the offensive on 1 November. Until October, the Americans had been stalled: the German second line held, the Argonne Forest was a maze, and the American supply system had broken down. The reorganisation of the command — Liggett taking the First Army, Bullard taking the Second — and the arrival of fresh divisions, together with a better-coordinated artillery preparation, broke the deadlock. The attack of 1 November, which was the best-planned American attack of the war, broke through the German lines in a day, and the Germans, who had no reserves left, could not stop the advance. The offensive, which had been a slogging match for a month, became a pursuit, and the Germans retreated towards Sedan and the Meuse.

The sources for Meuse-Argonne Offensive are uneven, and the historian must weigh them carefully. Official histories were written to justify decisions; unit diaries were written in haste and in the dark; memoirs were written years later, when memory had softened or sharpened; and the records of the losing side were often destroyed. Numbers differ between sources, sometimes widely, and the figures in this article are given as ranges for that reason. Where sources disagree, this article follows the most widely accepted modern scholarship, and says so when the evidence is genuinely uncertain.

6.2. The Tactical Lesson

A second turning point was the capture of Montfaucon on 27 September. Montfaucon was the key to the German defences, a high hill in the centre of the front, from which the Germans could observe the whole American advance, and its capture, though it took a day longer than planned, opened the way into the German second line. The battle for Montfaucon was the first great test of the American infantry, and it showed both their courage and their inexperience: the Americans took the hill, but at a heavy cost, and the delay in taking it allowed the Germans to reinforce their second line. The turning point of the offensive was therefore not a single day but a process: the Americans learned, in the fighting, how to fight a great battle, and by November they had learned enough to win it.

The numbers at Meuse-Argonne Offensive hide as much as they reveal. A division listed at full strength might have half its men sick, on leave or detached; a regiment that had fought for a week might be a shadow of itself; and the men counted as reinforcements might arrive without rifles, without training or without officers. Strength returns, the documents on which historians rely, are snapshots taken in the confusion of war, and they flatter the side that wrote them. The figures in this article should therefore be read as orders of magnitude — enough to show the balance of forces, but not precise enough to settle an argument to the last man.

6.2.1. How Turning Points Are Judged

Turning points are easy to name in hindsight and hard to recognise at the time, and Meuse-Argonne Offensive is no exception. The commanders who fought here did not know which hour would decide the battle; they knew only that the next attack might break the enemy or break their own men. Historians therefore judge a turning point not by a single dramatic moment but by what changed afterwards: whether supplies could still reach the front, whether reserves were still available, whether the losing side could still choose its next move. At Meuse-Argonne Offensive, the change was visible in the orders that followed, in the ground that changed hands and stayed changed, and in the reports that grew more confident on one side and more desperate on the other. That is the test this section applies: not the excitement of the moment, but the direction of everything that came after it, and the reasons why the initiative passed from one side to the other and did not come back.

7. Casualties and Losses

7.1. The Human Cost

The casualty figures for the Meuse-Argonne Offensive are usually given as about 122,000 Americans killed, wounded and missing, including 26,277 killed and about 95,000 wounded, and about 100,000 to 126,000 Germans killed, wounded and missing, including about 26,000 taken prisoner. The figures are not disputed in their broad outlines, and they are the official figures of the American and German armies. The American losses were the heaviest of any American battle in the First World War, and the Meuse-Argonne was the bloodiest battle in American history, in lives lost, until the Second World War. The German losses were also heavy, and the German Army, which had already lost a million men in 1918, could not replace them.

7.2. Counting the Losses

The figures also hide the cost of disease. The offensive was fought in the autumn of 1918, during the influenza pandemic — the Spanish flu — which killed more men than the fighting did, in the American Army as a whole, and which sickened tens of thousands of men in the Meuse-Argonne. The flu, the mud, the rain and the cold were as much a part of the battle as the German machine guns, and the men who fought in the Argonne remembered the mud and the sickness as vividly as they remembered the fighting. The Meuse-Argonne was a battle of endurance as much as of firepower, and the side that could endure won.

7.2.1. Wounds, Burial and Records

Behind every casualty figure lies a medical system under strain. Wounded men were carried from the firing line by stretcher-bearers, treated at aid stations, and evacuated — when the roads and the weather allowed — to field hospitals and then to base hospitals far behind the lines. Many of the wounded at Meuse-Argonne Offensive died not on the battlefield but of wounds, shock and infection in the hours and days that followed, and the difference between life and death often came down to how quickly a man could be reached and how far he had to travel. The dead were buried where they fell or in temporary cemeteries, and their names were recorded as best the circumstances allowed; in the confusion of battle, some were listed as missing for months or years. That is one reason why the figures in the table above are given as ranges: they are the best that the surviving records allow, not a precise count, and different historians, working from different archives, will always reach slightly different totals.

8. Map and Geography

8.1. The Ground

The Meuse-Argonne was fought in the rolling hills and forests of north-eastern France, between the Meuse River in the east and the Argonne Forest in the west, in a landscape of farmland, villages and woods, cut by rivers and ravines. The Meuse River, which runs from south to north, was the eastern boundary of the battlefield, and the Argonne Forest, a dense, tangled wood, was the western boundary. Between them lay the rolling ground of the Woëvre plain, with the high hill of Montfaucon in the centre, and the heights of the Meuse, to the east, which commanded the whole battlefield. The ground was difficult for an attacker: the forest was a maze, the hills were fortified, and the rivers and ravines channelled the advance into a few corridors.

8.2. Why the Ground Mattered

The weather also mattered. The offensive was fought in the autumn of 1918, in the rain and the mud, and the ground, which had been churned by four years of war, was a quagmire: the roads were mud, the fields were mud, and the men and the guns sank in it. The rain, which fell for much of the offensive, made the supply problem worse, and the cold, which came in November, made the suffering worse. The Meuse-Argonne was a battle fought in the mud, and the mud is remembered by the veterans as vividly as the fighting: the mud that swallowed boots, that stuck to guns, that made every step an effort. The geography and the weather of the Meuse-Argonne were the two facts that the Americans had to master, and they mastered them by endurance, not by skill.

8.2.1. Weather and Season

Weather and season were as much a part of Meuse-Argonne Offensive as any general’s plan. Rain turned roads to mud and grounded aircraft; cold froze the wounded where they lay and numbed the fingers of men trying to load their rifles; heat and dust choked engines and exhausted marching men. Darkness, fog and smoke hid movement but also made it impossible to tell friend from foe, and more than one unit in this battle fired on its own side or marched into the wrong position because the ground looked different in the dark. Commanders who understood the ground and the weather — who knew where the water would be, where the roads would hold, and how far a man could march in a day — had an advantage that no amount of firepower could replace. The map of Meuse-Argonne Offensive is therefore not only a record of where the fighting happened, but a reminder that geography and climate are actors in every battle, not merely its stage.

9. Outcome and Legacy

9.1. The Immediate Result

The Meuse-Argonne Offensive ended the First World War. The American advance, together with the French and British offensives on the rest of the front, broke the German Army, and on 11 November 1918, Germany signed the Armistice, and the war was over. The offensive was the largest American battle ever fought, and it made the American Army a great power: the United States, which had entered the war in April 1917 with a small army, ended it with an army of two million men in France, and with a claim to a place at the peace table. The battle is remembered in the United States as the birth of the modern American Army, and as the proof that the United States could fight a great war in Europe and win it.

9.2. The Longer Legacy

The legacy of the Meuse-Argonne is preserved in the Meuse-Argonne American Cemetery, at Romagne, the largest American war cemetery in Europe, where 14,246 American soldiers are buried, most of them killed in the offensive, and where the names of 954 men with no known grave are listed on the chapel walls. The cemetery is a place of pilgrimage for Americans, and the battle is remembered every 11 November, on Armistice Day — now Veterans Day in the United States — when the guns fell silent. The battle is also remembered for the Lost Battalion and for Alvin York, whose stories became legends, and for the sheer scale of the American effort: 1,200,000 men, in a battle that lasted 47 days and that ended a war.

9.2.1. How Historians Judge the Battle

Historians still argue about Meuse-Argonne Offensive, and the argument is part of the battle’s legacy. Some stress the decisions of the commanders and the quality of the plans; others stress the numbers, the logistics and the weather; still others stress the experience of the ordinary soldiers, whose courage and endurance decided what the plans could achieve. No single explanation is enough, and the honest historian leaves room for all of them. What is not in doubt is that the battle mattered to the people who fought it and to the families who waited for news of them, and that its effects — on the armies, on the civilians caught in the fighting, and on the course of the war — outlasted the last shot. The memorials, cemeteries and museums that mark the battlefield today are not only places of remembrance; they are also a warning. They record what happened when diplomacy failed and armies were sent to settle what politicians could not, and they ask every visitor to remember the cost.

10. Commanders

10.1. The American High Command

General John J. Pershing (United States). Commander-in-chief of the American Expeditionary Forces, who planned and directed the Meuse-Argonne Offensive. Pershing, known as Black Jack, had insisted that the Americans fight as an independent army, and he commanded the largest American battle in history. He later became General of the Armies, the highest rank in the American Army.

Lieutenant General Hunter Liggett (United States). Commander of the First Army from October 1918, who reorganised the offensive after it stalled and directed the breakthrough of the Kriemhilde Stellung and the final advance to Sedan. Liggett, a methodical and able commander, is credited with saving the offensive.

10.2. The Heroes of the Argonne

Major General Robert Bullard (United States). Commander of the Second Army, created in October 1918, which took over the eastern sector of the front and advanced towards Sedan. Bullard, a tough and aggressive commander, later commanded the Second Army in the final days of the war.

Sergeant Alvin York (United States). A soldier of the 328th Infantry Regiment, 82nd Division, who, on 8 October 1918, single-handedly captured 132 German soldiers and killed about 25, in one of the most famous actions of the war. York, a conscientious objector who had been persuaded to fight, was awarded the Medal of Honor and became a national hero.

Major Charles Whittlesey (United States). Commander of the Lost Battalion, the 308th Infantry Regiment, which was surrounded in the Argonne Forest from 2 to 7 October 1918 and held out for five days. Whittlesey, who was awarded the Medal of Honor, never recovered from the experience and killed himself in 1921.

10.3. The German Defence

General Max von Gallwitz (Germany). Commander of the German Fifth Army, which defended the Meuse-Argonne sector. Gallwitz, a veteran of the Eastern Front, directed the German defence of the Hindenburg Line and the Kriemhilde Stellung, and was forced back by the American offensive. He died in 1937.

10.3.1. Command and Responsibility

Command at Meuse-Argonne Offensive carried a weight that is hard to grasp from the safety of hindsight. The generals who ordered the attacks knew that their orders would kill men, including men they had served with for years, and they gave those orders anyway, because the alternative — inaction, retreat, delay — seemed worse. Some of them were right and some were wrong, and history has judged them accordingly, but the judgement is rarely simple: a commander who was cautious at Meuse-Argonne Offensive might have been reckless elsewhere, and a commander who won here might have done so by spending lives that a better plan would have saved. The biographies in this section should be read with that in mind. These were not figures in a legend but professional soldiers, working with incomplete information, under political pressure, and with the lives of thousands of men in their hands. Their decisions — good and bad — are the reason the battle took the shape it did, and the reason it is still studied today.

11. Frequently Asked Questions

When was the Meuse-Argonne Offensive?
From 26 September to 11 November 1918. The offensive lasted 47 days, and it ended on 11 November, when the Armistice was signed and the First World War ended.

Why is the Meuse-Argonne the largest battle in American history?
Because about 1,200,000 American soldiers took part, with 2,780 guns and 800 aircraft, and because the American losses — about 122,000 killed, wounded and missing, including 26,277 killed — were the heaviest of any American battle in the First World War, and the heaviest in American history until the Second World War.

What was the Lost Battalion?
Nine companies of the 308th Infantry Regiment, 77th Division — about 554 men, under Major Charles Whittlesey — who advanced into the Argonne Forest on 2 October 1918 and were surrounded by the Germans, cut off from their division, and held out for five days, until American troops broke through to them on 7 October. Only 194 men walked out.

Who was Alvin York?
Sergeant Alvin York, a soldier of the 328th Infantry Regiment, 82nd Division, who, on 8 October 1918, single-handedly captured 132 German soldiers and killed about 25, in one of the most famous actions of the war.

How many Americans died in the Meuse-Argonne?
About 26,277 Americans were killed, and about 95,000 were wounded, for a total of about 122,000 casualties. The Meuse-Argonne was the bloodiest battle in American history until the Second World War, and the dead are buried in the Meuse-Argonne American Cemetery at Romagne, the largest American war cemetery in Europe.

Did the Meuse-Argonne end the First World War?
Yes, in effect. The American offensive, together with the French and British offensives on the rest of the front, broke the German Army, and on 11 November 1918, Germany signed the Armistice. The Meuse-Argonne was the last great battle of the war, and it was the battle that forced Germany to sue for peace.
