The President of the United States of America takes pride in presenting the Legion of Merit (Posthumously) to Lieutenant Samuel Moore Logan (NSN: 0-111646), United States Navy, for exceptionally meritorious conduct in the performance of outstanding services to the Government of the United States as Engineering Officer of the U.S.S. HARDER (SS-257) and as Diving Officer during all attacks on the FIFTH War Patrol of that Submarine in enemy-controlled waters during the period 26 May to 21 June 1944. His exceptional performance of duty in the line of his profession contributed greatly to the success of his vessel in a series of brilliant and heroic actions against the enemy in which U.S.S. HARDER sank five fleet-type Japanese Destroyers within a period of five days, in hazardous and restricted waters in the immediate vicinity of the enemy fleet anchorage at Tawi Tawi, and despite the severest enemy air and surface countermeasures. The great skill which he exercised in maintaining perfect depth control on all attacks was a most important factor in these encounters and in the performance of a highly successful mission of reconnaissance of enemy fleet units. His courage and devotion to duty were an example and an inspiration to his fellow officers and crew. His actions and conduct throughout were in keeping with the highest traditions of the United States Naval Service.
