The President of the United States of America takes pleasure in presenting the Silver Star to Lieutenant Commander Sigmund Albert Bobczynski (NSN: 0-82637), United States Navy, for conspicuous gallantry and intrepidity as Assistant Approach Officer of the U.S.S. ARCHERFISH (SS-311), during the FIFTH War Patrol of that Submarine against enemy Japanese forces in waters south of Honshu, Japan, from 30 October to 15 December 1944. Displaying excellent judgment and a thorough knowledge of attack problems, Lieutenant Commander Bobczynski rendered invaluable assistance to his Commanding Officer in pressing home daring torpedo attacks against the enemy and on one occasion, following a six and one-half hour chase, aided in sinking a 28,000-ton aircraft carrier of the HAYATAKA Class. Continuing his valiant efforts throughout the patrol, he contributed to the success of the ARCHERFISH in evading enemy countermeasures. His ability, courage and devotion to duty reflect the highest credit upon Lieutenant Commander Bobczynski and the United States Naval Service.
