I encountered a convoy early at dawn. Situation favoured submerged attack.
Textbook attack at 2000m provided 3 hits out of four torpedoes fired. Sunk a tanker and damaged two freighters. No pursuit by escorts.
I matched with convoy's course, loaded torpedoes and surfaced. Contact was regained in an hour. Afternoon I got too close of the merchant which spotted me and opened fire. Escort raced to the scene too but it was evaded by diving.
Finally at dusk ready to overtake the convoy ship I was tailing disappeared from binocular view and sky turned grey. Soon after rain started.
Now that pisses me off.
