Setup: I am placed between the two lines where T3 tankers are going to pass in front and behind me at the same moment, the gap is pretty short, some 800 yards .... I am not comfortable because I don't remember if the Mk14 torpedoes have a minimum range before being active like the german torps were)... but no escorts in sight, fat targets...
I shoot a quick succession of 3 front torps on a T3, one on a smaller merchant nicely positioned behind it, turn the scope around and shoot two more at the T3 passing behind me. For some unknown(stupid greed!) reason, i stay at periscope depth.
boom boom.... boom.... boom!
Nice, only one dud this time, the aft T3 is going down, the other two ships are heavily smoking. I'm preparing to surface to finish the remaining T3 (no gun on the merchants...eh eh eh</sadistic laughter>). At this point, I look left and i see a torp heading right at us at about 200 yds.
Boom!
It wasn't a dud after all.
