Attacks on U-3 during this patrol
16 Apr 1940
The British submarine HMS Porpoise fired six torpedoes at U-3 about 10 miles southwest of Egersund, Norway and heard a detonation, which was a G7a torpedo from the U-boat that missed the submarine and detonated at the end of its run.
This attack was for a long time believed to have caused the sinking of U-1 but was in fact against U-3 which was not damaged.
