General Papagos yesterday have impression of greater optimism. He states indications led him to hope Yugoslavia might yet fight. He therefore reverted to question of holding Nestos position if Yugoslav collaboration at last moment made this possible. From the point of view of morale he emphasised fact that troops in Eastern Macedonia were recruited locally, and that, if fighting in forward positions would be defending their own homes. He remains anxious about lorry situation in view new supply difficulty, and urges that every available lorry be sent as early as possible.

     In baseball, the Philadelphia Phillies’ pitcher Hugh Mulcahy becomes the first major leaguer drafted and is inducted in the Army today. Mulcahy, an All Star in 1940 while leading the National League in losses for the second time, serves in the Army including a year in New Guinea and the Philippines. He was known as the "Losing Pitcher", with a career total of 45 wins, 89 losses, and an ERA of 4.49. He returns on July 11th, 1945 but he will pitch only 96 innings in 23 games before ending his career in 1947. More than 100 major leaguers will be drafted within the next two years, and two—Elmer Gedeon who played five games for the Washington Senators in 1939 and Harry O'Neill who played one game for the Philadelphia Athletics in 1939—will be killed in action.  (Michael Ballard and Jack McKillop)

ATLANTIC OCEAN: U-47 (Cdr Prien) is sunk by destroyer HMS Wolverine while attacking convoy OB293, 200 miles south-east of Iceland.

Current theory is that Guenther Prien wasn't actually sunk in this attack, but was lost to unknown causes. Apparently the belief among many is that the attack by Wolverine was on UA, which received damage but escaped the attacker. Wolverine then lost contact after following a school of porpoise. (Lawrence Paterson)

At 0109, SS Dunaff Head in Convoy OB-293 was torpedoed and sunk by UA south of Iceland. Five crewmembers were lost. The master, 34 crewmembers and four gunners were picked up by destroyer HMS Verity and landed at Loch Ewe.

Convoy SL-67 escapes attack from the German battleships Scharnhorst and Gneisenau because the battleship HMS Malaya is present. German Chancellor Adolf Hitler has ordered that no risk of damage to the ships is to be run if this can be avoided.

Between 0547 and 0608,U-124 fired six single torpedoes at Convoy SL-67 north of the Cape Verde Islands and observed four ships going down. Schulz reported five ships with about 33.000 tons sunk and another ship damaged. In fact four ships were sunk in the attack, the Nardana, Hindpool, Tielbank and Lahore.
