The Battle of Cantigny, fought May 28, 1918 was the first major American battle and offensive of World War I. The U.S. 1st Division, the most experienced of the five American divisions then in France and in reserve for the French Army near the village of Cantigny, was selected for the attack. The objective of the attack was both to reduce a small salient made by the German Army in the front lines but also to instill confidence among the French.

The 1st Infantry Division (1ID) is a combined arms division of the United States Army, and is the oldest continuously serving division in the Regular Army. It has seen continuous service since its organization in 1917 during World War I. It was officially nicknamed "The Big Red One" after its shoulder patch and is also nicknamed "The Fighting First." The division has also received troop monikers of "The Big Dead One" and "The Bloody First" as puns on the respective officially sanctioned nicknames. It is currently based at Fort Riley, Kansas.
