Okay, so you don't have radar. You can find the front corner position nearest you by sitting off to the side of the convoy. Ping them so you have a position point to plot on your nav map. You'll have to use the pencil and put the position on there yourself. Wait 3 minutes and do it again. The number of hundred yards between the two positions is the speed, connecting the positions and extending the line in the direction of travel gives you the speed.
Now it's time to position yourself ahead of the track, about 700 yards off and at right angles to the course. Ask your sonar man to track the closest contact and he should pick the front guy on your side. Listen around to verify. Then let him track again. Set up your TDC for AoB 80º starboard or port depending on what side of your sub they are coming from. If they're coming left to right (port to starboard) it's a starboard AoB. If they come starboard to port it's a port AoB. Enter the speed into the TDC. Make sure there is some range other than zero in the TDC first. Sight the periscope up 10º or 350º (toward the side they're coming from) and press the send range/bearing to TDC. You're ready to shoot.
Sit out there between 500 and 700 yards from the track, approaching at right angles. Listen to your sonar operator. If he's coming from left to right when the TDC operator says "Bearing 348" shoot one. When he says "bearing 351" shoot one. If he's coming from right to left, when he says "bearing 12" shoot one and when he says "bearing 9" shoot one.
Listen to him blow up and sink.
