I started a XXIII career last night, and of course first orders were to patrol shallow waters off the east coast of England, AN1941 Moray Firt.
Once on station spotted a lone merchant.
Caught up to her, got into position, and sent one fish her direction.
She took a while to slip beneath the surface, but one fish did the job.
U-2329
Jan 8th, 1945
Medium Modern Passenger/Freighter for 3713 tons.
One fish in the tube remaining.
