The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Silver Star to Sergeant Frederick Kosak, United States Army, for conspicuous gallantry and intrepidity in action against the enemy while serving as a Medical Aidman assigned to the 2d Field Hospital at Sememi, New Guinea, on 7 December 1942. Sergeant Kosak cared for the sick and wounded, working courageously and fearlessly, entirely oblivious of his personal safety, while continually being bombed and strafed by enemy planes. Especially noteworthy was his care of Major Daniel K. Edwards, previously wounded in action, whom he covered with mattresses and whose life undoubtedly was saved thereby, as the hospital tent in which he lay was riddled with projectiles, many men being killed and wounded. Sergeant Kosak’s gallant actions and dedicated devotion to his fellow man, without regard for his own life, were in keeping with the highest traditions of military service and reflect great credit upon himself, his unit, and the United States Army.
