If you must carry on after 1943 (which is like playing Russian roulette with 4 chambers loaded, IMO), here is one "crazy" idea which could turn the odds in your favor, at least for a little while.
If you know the bearing of the attacking DD, you could try
running towards it at top speed, to get under it before the DD can adjust its hedgehog launch time. Then you will be coping with its wabos instead. It's a trade-off, of course: you may survive the pass, but you will not "slip the noose," esp. if there is a hunter-killer team -- and you lose a bit more battery power each time.
Then again, maybe you will have some interesting tales of an engagement lasting several hours, with the oxygen or the battery power running out! Happy Days!
