The President of the United States of America takes pleasure in presenting the Navy Cross to Commander Thomas Michael Dykers, United States Navy, for extraordinary heroism in the line of his profession as Commanding Officer of the U.S.S. JACK (SS-259), on the FIRST War Patrol of that submarine during the period 5 June 1943 to 19 July 1943, in enemy controlled waters off the coast of Honshu, Japan. Skillfully maneuvering his ship into striking position, Commander Dykers attacked the enemy with aggressive determination and outstanding courage and succeeded in sinking or damaging a large amount of hostile shipping. Despite fierce enemy opposition, he employed skillful evasive tactics and brought his ship safely back to port. Commander Dykers’ superb seamanship, initiative, and inspiring leadership reflect great credit upon his command and the United States Naval Service.
