Attacks on this boat and other events

3 Jul 1943
The sinking of U-628 1405hrs, NW of Cape Ortegal, outbound: British Liberator FL963 (224 Sqn RAF/J, pilot S/L P.J. Cundy, DFC) dropped 18 35lb A/S bombs on an initial attack run (the first use of this new weapon), then followed up with four depth charges. Survivors were seen in the water after U-628 sank, but none were rescued. Despite flak hits to a fuel tank and the fin, rudder and starboard wing, the aircraft returned to St. Eval to make a safe landing. (Sources: Franks/Zimmerman)

1 recorded attack on this boat.

Men lost from U-boats

Unlike many other U-boats, which during their service lost men due to accidents and various other causes, U-628 did not suffer any casualties (we know of) until the time of her loss.
