The President of the United States of America takes pleasure in presenting the Navy Cross to Commander Donald Frederick Weiss (NSN: 0-62675), United States Navy, for extraordinary heroism in the line of his profession as Commanding Officer of the U.S.S. TINOSA (SS-283), on the FIFTH War Patrol of that submarine during the period 10 January 1944 to 4 March 1944, in enemy controlled waters of the South China Sea. With courage, skill and determination, Commander Weiss aggressively attacked and delivered torpedo attacks against heavily escorted enemy convoys. Despite enemy gunfire, he tenaciously pursued his targets, launching repeated torpedo attacks until he was forced to use evasive tactics in avoiding serious damage from the enemy counter-measures. By his outstanding aggressive spirit, and exceptional seamanship, he successfully sank three enemy freighters totaling over 16,900 tons and damaged two freighters totaling over 9,000 tons. Despite severe enemy gunfire and depth-charge counter-attacks, he brought his ship to port undamaged. His conduct throughout was an inspiration to his officers and men and in keeping with the highest traditions of the United States Naval Service.
