[Fish40]

After sinking three freighters in the Formosa Straites, I get a radio message of a large convoy which will transit my area in two days time. I meet the heavily escorted convoy, luckily in the middle of the night, right on time. I position myself for the attack, and fire at two 8k ton freighters with 3 torpedoes each. All six fish hit, and both went down. After a prolonged but ineffective counter attack, by the escorts, I'm ready to run down the convoy again for another attack. Here's my delemma. I only have 1 bow torpedo left, but a full complement of stern torpeoes. Would it be wise to make a deliberate attack useing the stern tubes, or RTB with 9 torpedoes and be satisfied with my 25k tons sunk?
