The President of the United States of America takes pleasure in presenting the Navy Cross to Lieutenant Commander Carl Tiedeman (NSN: 0-72440), United States Navy, for extraordinary heroism in the line of his profession as Commanding Officer of the U.S.S. GUAVINA (SS-326), on the FIRST War Patrol of that submarine during the period 6 April 1944 to 28 May 1944, in enemy controlled waters of the Pacific War Area. By his courage and determination, Lieutenant Commander Tiedeman was able to penetrate strong enemy escort screens and attack enemy convoys. As a result of his aggressive torpedo and gun attacks, he successfully sank three enemy freighters and an enemy trawler totaling over 19,500 tons. In spite of severe enemy counter-attacks, his skillful evasive tactics enabled him to escape and bring his ship to port undamaged. His conduct throughout was an inspiration to his officers and men and in keeping with the highest traditions of the United States Naval Service.
