Caught 'em with their pants down. Surfaced, approached the convoy with a half-moon behind me, not an escort in sight. A spread of four torps yielded three hits...two large cargos down, 12,000 tons each. That's three out of this convoy thus far. Am moving behind the convoy for an approach on the other side while I reload the tubes.
GWX just rocks. And Freetown is my new favorite hunting ground.
