The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to Captain Lester Sherwood Wass (MCSN: 0-3538), United States Marine Corps, for extraordinary heroism while serving with the Fifth Regiment (Marines), 2d Division, A.E.F., in action in Bois-de-Belleau, France, 11 June 1918, and near Vierzy, France, 18 July 1918. In the Bois-de-Belleau, when all the officers of his company had become casualties, Captain Wass displayed marked heroism in leading his men forward in the face of heavy machine-gun fire, assisting in the capture of many machine-guns. Near Vierzy he fearlessly exposed himself to enemy machine-gun and artillery fire, directing personally the reduction of strong points. He was killed at the head of his men, while leading an advance.
