The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Silver Star to Lieutenant Commander Francis David Walker, Jr. (NSN: 0-75075), United States Navy, for conspicuous gallantry, intrepidity and coolness in action against the enemy while serving as Executive Officer and Navigator of the U.S.S. CREVALLE (SS-291), during the FIRST War Patrol of that submarine in enemy Japanese-controlled waters, from 27 October 1943 to 7 December 1943. A skilled and inspiring leader, Lieutenant Commander Walker was instrumental in training the crew of his ship to a high state of combat efficiency, thereby assisting his Commanding Officer in the conduct of vigorous strikes against heavily escorted Japanese convoys which resulted in the sinking of four ships, including an auxiliary aircraft carrier, and the damaging of additional shipping. By his outstanding performance of duty in the face of persistent countermeasures by hostile escort craft, Lieutenant Commander Walker contributed materially to the safe return of his submarine to port after a highly effective patrol, and his gallant conduct throughout was in keeping with the highest traditions of the United States Naval Service.
