in my experience with 1939 destroyer AI:

- you can avoid them very easily if u set silent running and manually set speed to 0.5 knot (click on the spedometer btwn 0 and 1).
- do not turn off silent running to attempt to reload.
- you can only do 'ahead slow' once they are more than 5km away.
- do not use observation scope (O) or attack scope (F3) when your boat is moving.
- only use observation scope when u are stationary (0knot), avoid using the attack scope like the plague, they can see that very very easily it seems.
- do not fully extend the observation scope, only extend enough so u can see things.
- avoid using scopes if can be helped, use sonar contact to update their guestimated location.

general steps to lure and kill destroyers (1939 period only, havent experiment with late stage dessy):
- when they are coming for you from like 6-8km range dive and set speed to 0.5kt + silent running, this will make u disappear from their sensors. When you initially dive, you should should still have pretty high speed for a brief moment (5-6knot), make use of this speed to get to a favorable angle/firing position.
- bear in mind they will usually head straight to the last spot where u were detected and will travel straight to said spot and start their scan from that spot. Make use of this opportunity when they are on this headlong path and torp them.
- if they are already there and are running in random circles looking for u, use patience and dive away to about 600meter distance from their circular search pattern, stay on periscope depth as often as possible. their asdic seems blind vs close to surface depth @ 0.5knot. swing around to wait for oppotunity.
- at around 600m to 1km, with your bow facing their general direction, set torp to high speed and shoot when their hull is about to circle to (not after) directly 90 degree facing you (broadside), at that angle and close range it takes a miracle to avoid ur torp. Note when u are doing 0.5 knot ur boat turn slow as hell, you will need to use judgement on whether if they will still be there after the turn is completed. use the rear tube to shoot them to avoid making this long turn if u still have a fish in there (having a fish in rear tube always means the first destroyer that come for u is a free kill).
- when shooting your torp, only surface ur observation scope for a brief moment, dont linger the scope above water to see explosion, instead retrieve it and wait til 10sec before impact and raise it again to see the impact (if u really want to see them asplode).
- watch ur depth very very carefully, when u travel below 2 knot, the boat depth can change 1-2meter on random chance. this can make ur conn tower go above water, especially when coupled with rough/semi-rough sea condition.

additional info:
- at around early november 1939 the channel is mined according to BDU radio message.

edit:
disclaimer: if u use the above tactic and gets killed. do not blame me

happy hunting.
