The Meuse-Argonne Offensive was the largest in United States military history, involving 1.2 million American soldiers.
It was one of a series of Allied attacks known as the Hundred Days Offensive, which brought the war to an end.
The battle cost 28,000 German lives, 26,277 American lives and an unknown number of French lives.
It was the largest and bloodiest operation of World War I for the American Expeditionary Force (AEF),
which was commanded by General John J. Pershing, and the second-deadliest battle in American history.
U.S. losses were exacerbated by the inexperience of many of the troops and the tactics used
during the early phases of the operation. Meuse-Argonne was the principal engagement of the AEF during World War I.
