Not Bad for a Dugout Canoe...
Found The Passenger Liner on the Prior Patrol, Docked in Poti on the coast of the Black Sea. Fired two eels at her, not realizing that she was on the opposite side of a levy..

So, this patrol we came in from the other side and put two into her, she went down like a setting sun.
The Motor Vessel was a lone ship docked in an unprotected port north of Poti, she made good target practice for the Flak gunner, and a powerful show of force to Germany's Red northern Neighbor.
The Heavy Transport was plucked like a ripened peach from a small convoy.
The Tanker is one of two docked small tankers we fired upon in another poorly protected russian port. these two used the last of the 6 torpedoes, The ship sunk was parked 90 degrees across our heading, and the other was a bow shot. Both Torps ran true, but the second bar maid had luck with her that night.
