Meuse-Argonne Offensive Timeline

An overview of the major events of the Meuse-Argonne Offensive.

The Meuse-Argonne Offensive, September 26 to November 11, 1918, was the largest single battle to date in American History, and demonstrated the progression of the United States into a global power. 

Leading up to September 26, 1918, American troops moved into position for the Meuse-Argonne offensive under the cover of darkness. Remarkably, over 600,000 American soldiers moved into position without alerting the enemy.

 The goal of the offensive was to capture Sedan, a key location for German train transport.

On September 26, 1918 at 5:30 a.m. The U.S. First Army launches its assault. Montfaucon is captured on the following day, and by September 30, the U.S. Army had driven enemy forces back as far as six miles.

During the second phase of the offensive, additional German divisions arrive from other battlefronts. Despite this, the U.S. Army captures the Argonne Forest on October 7, 1918 and crosses the meuse on October 8.

They penetrate the Hindenburg Line on October 9 and seize the Heights of Cunel and Romagne on October 14.

During the final phase of the offensive, the American forces attack at daybreak on Nocember 1, 1918 advancing across the Meuse, and to capture Barricourt. That night the Germans retreat.

The enemy is in full retreat by November 4, when the U.S. First Army continues with additional crossings of the Meuse River. By November 7, the U.S. Army had captured the heights overlooking Sedan, the initial target of the offensive. On November 10, the Germans seek an immediate armistice which goes into effect on November 11 at 11 a.m.
