of Hamel on 4 July. Individual platoons from four companies from the 131st Infantry and 132nd Infantry were distributed among Australian battalions, to gain combat experience. This, however, occurred without official approval as there was controversy regarding the battlefield command of US troops by junior officers from other countries. Thus, while Hamel was a relatively minor battle by the standards of World War I, it was historically significant as the first occasion on which US Army personnel had fought alongside British Empire forces, and demonstrated that the previously inexperienced American troops could play an effective role in the war. The battle was also historically significant for the use of innovative assault tactics, devised by the Australian General John Monash, were demonstrated. The 33rd Division was in reserve behind the British Fourth Army at the opening of the August offensive for emergencies only. With the British III Corps attack stalling at Chipilly Ridge during the Battle of Amiens, the 131st Regiment of the 33rd Division was sent to assist on 9 August, which it did with distinction.

The 33rd Division was the only unit in the war to have machine gun barrage enemy nests while infantry turned the position. In total, the 33rd Division received 215 American decorations, 56 British decorations, and various others. As result of its World
