I tend to approach from the front of the convoy at a depth of about 40 metres and hope that the lead escort doesn't detect me. Once I'm within the convoy I turn to get into the best firing position, go up to periscope depth, pick my targets and fire my torps. I have been detected by the lead escort on many occasions and been depth charged but once I'm under the convoy itself there is a brief opportunity to sink some ships.
