St Eval Ops
RMVENTURI
A sub on the surface might be Allied, perhaps damaged. Recognition was difficult and many whales were depth charged by crews who could just see the shape below the surface. Most attacks were on subs sighted on the surface re-charging batteries. Under the low cloud an aircraft usually spotted the sub too close to attack, and had to turn a full circle, giving the sub time to dive. The rear gunner would fire continuously at the Conning Tower to try to prevent the deck crew to get below. fredjhh
