Just as a follow-up here's a thumb to a screen of the exact tactic I mentioned.
please excuse the quality of the edited image as this entire patrol so far in line with this topic has been crudy weather, and at night
U49 VIIB on patrol I botched an intercept but got in behind and UZO`ed a nice Cargo. Worked out too because just before the hit the watch crew reported "ship spotted". I'm thinking well duh, but it was actually another Cargo on an opposite course. So with Cargo(1) now reduced to a crawl I intercepted the 2nd ship and UZO`ed it as well, finished it off with the deck gun, then returned to a marked stationary fat target. A dozen or so shots to the waterline and she's all done.
Kind of goes to show you never know what will pop out on what you might be thinking as a boring old patrol, 12:30 at night, eyes getting heavy, thinking what am I doing. Has she called for help? Will an armed trawler or DD be charging in?
Bring it the frick on
But I did have to get to sleep, work and all, not to mention more snow in the last 3 days then we have had in the last month to deal with in the morning.
