The President of the United States of America takes pleasure in presenting the Navy Cross to Lieutenant Commander Francis David Walker, Jr. (NSN: 0-75075), United States Navy, for extraordinary heroism in the line of his profession as Commanding Officer of the U.S.S. CREVALLE (SS-291), on the THIRD War Patrol of that submarine during the period 4 April 1944 to 28 May 1944, in enemy controlled waters of the South China Sea. Skillfully maneuvering his ship into a favorable position to strike at enemy shipping and in the face of heavy enemy countermeasures, Lieutenant Commander Walker launched attacks to sink two enemy ships totaling 26,414 tons and probably sank an additional vessel of 7,499 tons. Despite a severe enemy counter attack, he skillfully directed his ship in the successful completion of a special mission, bringing her to port without serious injury to the ship or crew. Commander Walker’s inspiring leadership and devotion to the fulfillment of his hazardous missions reflect the highest credit upon himself and the United States Naval Service.
