Hi Joe,

April 23rd, 1943 U-91 (Type VIIC) Commanded by Heinz Hungershausen rescued 4 survivors from U-752 (Type VIIC) commanded by Karl-Ernst Schroeter after U-752 was sunk in a rocket attack by a Swordfish aircraft. This was possibly the first U-boat sunk by rockets from a carrier aircraft.

I know there were others but I don’t have the details at hand.
