BB attack

[mowgli99]

So i was sailing in bf 52 (the shallow part) and i was submerged. I picked up multiple hydro contacts and knew it was a convoy. I set intercept. About an hour later i raised my scope. I was in the middle of the convoy and saw a revenge bb 5000m from me. Although it was moving slowly i ended up behind it. My plan was to use mag. fish to blow the props off. Two mags detonated under keel which should have been a back breaker. It continued happily along. i only had one more torp and it was in stern. I used on a whale facotry and it sunk. Iwas then put down by dds and eventuall ran aground and sunk. Sad no. This was my first sighting of a sailing bb.
