The President of the United States of America takes pleasure in presenting the Navy Cross to Major [then Captain] Gilder D. Jackson, Jr. (MCSN: 0-469), United States Marine Corps, for extraordinary heroism while serving with the 43d Company, 5th Regiment (Marines), 2d Division, A.E.F., near Vierzy, France, in action early on the morning of 18 July 1918. As Second in Command of the 43d (F) Company, Fifth Marines, while on a mission to establish liaison with a neighboring unit, Major Jackson discovered an enemy battery firing on our supporting tanks from a position concealed in a wheat field. With a splendid display of initiative and leadership, he gathered together a few men whom he organized and most skillfully and gallantly led against this position, capturing many prisoners, including two officers, four pieces of artillery, two mobile trench mortars and undoubtedly saved to the battalion by his timely act the five undamaged tanks that played such an important role in the later action.
