Battle of the Atlantic

• U-boats attack Convoy SC-130, but on this occasion come up against supporting B-24 Liberators deploying homing torpedoes. Since early April, 14 of 22 convoys have crossed the North Atlantic without loss. No longer can the ageing U-boats cope with the advanced tactics employed by the Allies on sea and in the air. More than 30 U-boats have been sunk in the first 3 weeks of May.
• Flying support of convoy SC-130, Hudson 'M' of No 269 Squadron sights 273, but the U-boat dives before an attack can be made. The aircraft then carries out baiting tactic and the U-boat is again sighted. Four depth charges are dropped and perfectly straddle the conning tower. Several men in the conning tower begin to shoot at the aircraft which in turn makes a strafing run after which the U-boat is seen sinking.<
• The corvette HMS Snowflake, escorting convoy SC-130, detects a U-boat, U-381, on her asdic coming in to attack the convoy from the starboard side of the convoy. Snowflake drops a depth charge pattern, but is soon relieved by the destroyer Duncan whose first pattern went down as the convoy's ships passed by. The next attack is with a Hedgehog which produces a hit and a large oil slick.

• U-954 is sunk by hedgehog attacks from the Banff-class sloop HMS Sennen and the River-class frigate HMS Jed, both escorting Convoy SC-130. One of those killed in the sinking was Adm Karl Dönitz's son Peter Dönitz.
