Lucien L. Arsenault entered the military service in Maine. He served in the U.S. Army during World War I as a Private in the 103rd Infantry Regiment, 26th Infantry "Yankee" Division. He died on July 20, 1918 and is now buried in Aisne-Marne American Cem., Belleau, France. He was awarded the Distinguished Service Cross for extraordinary heroism in action while serving with Company B, 103d Infantry Regiment, 26th Division, A.E.F., near Torcy, France, July 18, 1918. When he declined to leave his platoon for treatment, though severely wounded in the leg by machine-gun fire, continuing with the advance of his platoon, Private Arsenault was again wounded and again refused to go to the rear, but continued with the assaulting line until he received a third wound, which caused instantaneous death. His high courage, unselfish devotion to duty, and utter disregard for his own safety, raised the morale of his company to a high pitch and spurred them on to great endeavors.
