The Battle of Gettysburg and Meuse-Argonne Offensive are both battles fought during what?
Meuse-Argonne Offensive The Meuse-Argonne Offensive, also known as the Maas-Argonne Offensive and the Battle of the Argonne Forest, was a major part of the final Allied offensive of World War I that stretched along the entire Western Front. It was fought from 26 September 1918 until the Armistice of 11 November 1918, a total of 47 days. 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 and 26,277 American 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 one of the deadliest battles in American history. American losses were exacerbated by the inexperience of many of the troops, and tactics used during the early phases of the operation.
American Expeditionary Forces The American Expeditionary Forces (AEF) was the expeditionary force of the United States Army during World War I. It was established on July 5, 1917, in France under the command of General John J. Pershing. During the United States campaigns in World War I it fought alongside the French Army, British Army, and Canadian Army on the Western Front, against the German Empire. A minority of the AEF troops also fought alongside the Italian Army in that same year, against the Austro-Hungarian Army. The AEF helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château-Thierry (1918) and Battle of Belleau Wood) in the summer of 1918, and the AEF fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918.
