The President of the United States of America takes pleasure in presenting the Navy Cross to First Lieutenant Jonas Henry Platt (MCSN: 0-770), United States Marine Corps, for extraordinary heroism while serving with the 5th Regiment (Marines), 2d Division, A.E.F. in action near the Bois-de-Belleau, Chateau-Thierry, France, 6 June 1918. Seriously wounded in the leg early in the engagement, First Lieutenant Platt continued to direct, the operations not only of his platoon but of another. He charged and drove off the crew of an enemy machine-gun, supervised the disposition and digging in of a large part of his company, and yielded command only when exhausted from pain and loss of blood.
