Attacks on U-66 during this patrol

3 Aug 1943
21.35 hrs, mid Atlantic: the boat was surprised by a Avenger/Wildcat team (VC-1 USN) from USS Card. The aircraft made several strafing runs and one depth charge apparently exploded directly under the boat. The II.WO, Oblt Kurt Sch├╝tze, and Mtrgfr Erich Lorenz were killed and MechGfr Heinz Nitsch died of wounds during the night. The commander and FzS Pfaff were seriously wounded and the I.WO and five ratings were slightly wounded. U-117 was ordered to meet U-66 three days later for medical assistance and to transfer a replacement WO. (Sources: Ritschel)
