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 Commander [then Lieutenant Commander] Robert Irving Olsen (NSN: 0-72583), United States Navy, for conspicuous gallantry and intrepidity as Commanding Officer of the U.S.S. ANGLER (SS-240), during the FIRST War Patrol of that Submarine in enemy-controlled waters from 10 January to 4 February 1944. Following a relentless, prolonged pursuit of a four-ship hostile convoy, Commander Olsen skillfully maneuvered to strike vigorous and daring night surface attack to damage or destroy and important amount of Japanese shipping despite severe hostile countermeasures and, in addition, directed a brilliantly executed gun engagement against an armed enemy trawler, resulting in its destruction. By his expert evasive tactics, his forceful and aggressive leadership and gallant fighting spirit of his officers and men, Commander Olsen succeeded in bringing his ship safe to port undamaged after carrying out his perilous mission. His unwavering devotion to duty throughout was in keeping with the highest traditions of the United States Naval Service.
