On June 6, 1944, Summers landed as part of the first night drop of troops during the American airborne landings in Normandy. His unit had captured Saint-Germain-de-Varreville, France, near Exit 4 off Utah Beach. Summers and 15 soldiers were ordered by 1st Battalion commander, Lt Col. Patrick Cassidy, to capture a building complex nearby designated "WXYZ" on the field order map. The buildings turned out to be the barracks for 100 or more German soldiers.
