Most overshot, but one fell close, causing only minor damage, but with serious consequences. On diving, damage to the Schnorchel caused carbon monoxide poisoning of the crew. One man died and the boat was forced to return to base. [Matrosenobergefreiter Matthias Mittler] (Sources: BdU KTB/Norman Franks)
