The President of the United States of America takes pleasure in presenting the Navy Cross to Lieutenant, Junior Grade [then Ensign] Jack Greenwell, United States Naval Reserve, for extraordinary heroism in operations against the enemy while serving as Pilot of a carrier-based Navy Dive Bomber of Bombing Squadron NINE (VB-9), attached to the U.S.S. YORKTOWN (CV-10), during action against enemy Japanese forces in the East China Sea on 7 April 1945. Undaunted by intense anti-aircraft fire and a low cloud cover which obscured the target, Lieutenant, Junior Grade, Greenwell pressed home a glide-bombing attack against units of the enemy Fleet including a battleship, a cruiser and screening destroyers, scoring direct hits on the fantail of the cruiser and contributing to its sinking. His airmanship and devotion to duty were in keeping with the highest traditions of the United States Naval Service.
