The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Chief Gunner’s Mate Benjamin H. Groves, United States Navy, for exceptionally meritorious and distinguished service in Command of the Armed Guard of the S.S. Nyanza. On 13 January 1918, the Nyanza engaged a submarine in gunfire for two and one-half hours and apparently hit the submarine. The evidence shows that the ship was undoubtedly saved by the prompt and efficient work of the Commander of the Armed Guard and gun’s crew.
