The President of the United States of America takes pleasure in presenting the Navy Cross to Lieutenant Commander Frederick Burdett Warder, United States Navy, for extraordinary heroism in the line of his profession as Commanding Officer of the U.S.S. SEAWOLF (SS-197), during the FOURTH War Patrol of that submarine during the period 25 February 1942 to 1 April 1942, in enemy controlled waters near the coast of Java. In extremely shallow and narrow waters where very strong currents exist off the coast of Java, Lieutenant Commander Warder attacked and sank a Japanese destroyer and one large transport which were part of a heavy screened force. Off Christmas Islands, Netherlands East Indies, he made repeated attacks on enemy light cruisers which were heavily screened by destroyers, sinking one cruiser and heavily damaging two others, one of which probably sank. All attacks were followed up to short ranges in the face of active enemy opposition, and after each attack his submarine was the target of heavy, prolonged, depth-charge counter-attacks by the enemy. Through his experience and sound judgment Lieutenant Commander Warder brought his ship through unscathed. His conduct throughout was an inspiration to his officers and men and in keeping with the highest traditions of the United States Naval Service.
