 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.

 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.

 To avoid the risk of having extensive German reserves massed against a single Allied attack, the assault along the Canal du Nord was undertaken as part of a number of closely sequenced Allied attacks at separate points along the Western Front.
 It began one day after the Meuse-Argonne Offensive, one day before an offensive in the Flanders region of Belgium and two days before the Battle of St. Quentin Canal.
