It is historically accurate

...for the destroyers not to chase you for very long. I found a little ditty here that explains it. Its about a minute into this clip.

Depends on the role of the destroyer.

Yes that is certainly realistic for convoy escorts, there one and only priority was to bring as many merchants safley back to port. it was not there job to go galavanting off to hunt Uboats to the death (a la SH3), but to stick to the convoy like glue and force the Uboats to go deep where they couldn't attack and were too slow to persue.

Its a different story for Hunter killer groups though.....they would hunt a single uboat for days on end if needed.
I remember this was discussed before SHV was released, it was agreed that SHV needed more than one set of escort AI behaviour (offensive and defensive) for this very purpose.

that's right, in the early part of the war when escorts were in short supply, they would just try to hold down the U-Boat for a few hours and race back to the convoy. That was usually enough to leave the U-Boat out of position and unable to launch another attack.

later on, when they had a lot more escorts and continuous air cover, the Allies could afford to park 2-3 escorts or a whole HK group over a single boat for the 1-2 days it could take to kill it or force it to the surface.

Escorts often had to break off to get back to keeping other u-boats at bay, and they also might have been best placed to attempt to pick up survivors.

This thread reveals interesting information...

My question is: What would be the best tactic from the U-Boats commander where he is up against a HK group out for his destruction where they are willing to wait till hell freezes over to get him?

Could he surface and immediately surrender? What would be the consequences of this?

Could he come up for a quick refresh of air and then dive again for another day or so under? Is it possible to get enough fresh air quick enough before the DDs found him?

I'm thinking of a scenario where he sitting on the bottom at 120 meters acting like a rock.

I've read before that submarine commanders who surrendered their ship were treated fairly badly by their comrades in the POW camps. I can't remember which commander, who abandoned his ship by jumping onto the nearby destroyer was tried by an unofficial 'court' in the POW camp.

I'm fairly sure that If he came up for air whilst the DD's were in eyeball range then the ship would look like Swiss cheese in fairly short order. - And in some cases DD hunter groups would search for many many hours if they thought there was a u-boot nearby!
