Now patrolling the east coast of England and I spent my last 3 torps. Will be putting into Heligoland for a resupply.
This Rongel class merchant took my last 3 torps. I couldn't surface to attack with the 88 as there were 2 warship sound contacts in the area.
...and sure enough, they both came to check out the commotion!!
...so I went deep and quiet and shook them both after about 40 mins.
