The Battle of Hamel (4 July 1918) was a successful attack launched by the Australian Corps of the Australian Imperial Force and several American units against German positions in and around the town of Le Hamel in northern France during World War I. The battle was planned and commanded by Lieutenant General John Monash (later knighted). The battle was the first time in the war that American troops participated in an offensive action under non-American command. Ten American companies joined with Australian troops under Australian command, although six were recalled before the battle.
