The President of the United States of America takes pleasure in presenting the Silver Star to Commander Marvin John Jensen (NSN: 0-70206), United States Navy, for conspicuous gallantry and intrepidity as Commanding Officer of the U.S.S. PUFFER (SS-268), during the FIRST War Patrol of that Submarine in enemy controlled waters from 7 September to 17 October 1943. Directing his ship courageously and with exceptional skill throughout twenty-four hours of intense enemy depth-charging attacks, Commander Jensen maintained his vessel at periscope depth and pressed home his attacks boldly and with heroic aggressiveness, destroying a valuable enemy merchantman. Although his submarine sustained serious damage during the vigorous engagement, he nevertheless returned her safe to base under her own power, thereby saving one of the important units of the Fleet for further service. Commander Jensen’s expert seamanship and indomitable fighting spirit were an inspiration to his crew and were in keeping with the highest traditions of the United States Naval Service.
