14 Feb, 1940.
Hinze Bido spots a massive convoy in the North sea, reports it in and begins the attack.
It did not go well.
Sunk two large freighters at long range with Type Is
Norwegian large freighters escorted by British ships..
And those escorts drop perfection in depth charges, and U-53 was placed at the bottom of the sea.
So one commander down - 9/1939 to 2/1940 - 25 Ships sunk - 22 Freighters, 3 military, for 73k tons of Merchants and 9.2k in warships.
Next commander will start in 3/1940
