Meuse-Argonne Offensive Begins in World War I

Context

By the summer of 1918 the Allies had blunted the final German spring offensives along the Western Front. Fresh American divisions arriving in France gave Supreme Allied Commander Ferdinand Foch the manpower needed for a coordinated series of counterattacks that became known as the Hundred Days Offensive. Foch directed separate thrusts by British, French, and American armies designed to keep the Germans off balance and prevent them from shifting reserves.

What Happened

On the night of September 25 a massive Allied artillery barrage, including chemical shells, pounded German positions in the densely wooded Argonne Forest and the heights east of the Meuse River. At 5:30 a.m. on the 26th, more than 700 tanks rolled forward with infantry from the U.S. First Army under General John J. Pershing and supporting French units. The initial advance captured thousands of prisoners and several miles of ground, though dense forest, fortified machine-gun nests, and determined German resistance quickly slowed momentum.

Aftermath

Pershing halted the first phase on September 30 to reorganize; the offensive resumed on October 4 with fresh divisions. Fighting continued for another five weeks as American and French troops pushed northward, eventually advancing more than thirty kilometers in some sectors. Exhausted German units, facing the broader collapse of the Central Powers, began a general retreat that ended only with the Armistice on November 11.

Legacy

The Meuse-Argonne campaign proved the combat effectiveness of the American Expeditionary Forces and helped convince German leaders that continued resistance was futile. Its scale and cost shaped postwar U.S. military planning and contributed to the creation of veterans’ organizations that preserved the memory of the war’s final months.
