The U.S. 30th Infantry Division was part of the U.S. Army Corps II, which was assigned to British and Australian units for training and combat during the First World War - hence why these Doughboys are pictured with a British Lewis Gun, and why they were in Flanders to begin with, as the rest of the American Expeditionary Force was positioned in or near Lorraine.
Some 50,000 U.S. troops from the 27th and 30th Infantry Divisions were initially trained under British command, but their most significant contribution in the First World War came under Australian command during the Battle of the St. Quentin Canal in September - October 1918.
These U.S. forces spearheaded the attack on September 29, 1918 and met stiff German resistance, suffering a staggering 7800 casualties on the first day and 13,182 by the end of the battle.
By the end of the First World War the 27th Division had suffered 1,442 deaths and another 6,892 wounded or missing. The 30th Division had suffered 1,237 deaths with 7,178 wounded and missing.
The U.S. 33rd Infantry Division also fought under Australian command and participated in the Battle of Hamel on July 4, 1918 - with Australian General Monash deliberately choosing the U.S. Independence Day for the battle as a gesture and source of motivation for his American troops. The 33rd Division also fought with the Australians in the Battle of Amiens in August 1918.
However, U.S. General Pershing was dissatisfied with the use of American troops and recalled the 33rd Division on August 23, which joined the rest of the American Expeditionary Force afterwards, eventually participating in the Meuse-Argonne Offensive.
By the end of the war the 33rd Division had suffered 691 deaths and 6,173 wounded or missing.
