The HMT Rohna, a British troop transport, is attacked in the eastern Mediterranean by a Luftwaffe plane using a radio-guided bomb, sinking the ship and killing 1,015 American GIs and 135 British and Australian service men. It is the largest loss of U.S. servicemen at sea in the war. The disaster is kept secret, as the Allies did not wish to disclose that the Germans possessed such an intimidating weapon. Consequently, the destruction of the Rohna will remain virtually unknown to the public for many years after the war.
