The 27th Infantry Division was a unit of the Army National Guard in both World Wars. The Division traces its history from the New York Division, formed originally in 1908. The 6th Division designation was changed to the 27th Division in July 1917. They took part in The Meuse-Argonne Offensive, also known as the Maas-Argonne Offensive and the Battle of the Argonne Forest, the final Allied offensive of WWI that stretched along the entire Western Front. During the Somme offensive (September 24 - October 1) the 27th engaged in severe fighting along the Saint Quentin Canal Tunnel. Following heavy losses, they were placed into reserve for rest and replacements. Six days later the they were back in action, and in conjunction with AEF 30th Division and British forces 27th, they broke the Hindenburg line and forced a German retreat from their defensive line. Armistice ended the fighting and the division was sent home in February 1919, to be mustered out several months later.
