Not as interesting as the movie U-571, which was evidently based on a "true" story. Apparently the Americans captured the enigma on a U-boat and even repaired it and sailed it despite not knowing how to read any of the instruments.
Aren't we lucky that hollywood teaches us history?

This u-boat was capture by the British, and they more than likely had someone who could read the instruments.
As for that movie, I'm glad to see you have a good sense of humor.

U 570 ( VIIC ) was captured in 1941
Commisioned as HMS Graph Sept 41
U110 ( IXB Lemp ) was captured before that in may 41 which is where the enigma and all releated codes were found
"accidentally" sank when being towed to Britain
Yes that video is about U-570 :yep:
If you are interested in reading the reports made both by the americans and british teams who inspected the ship, they are here together with much more info:

It is interesting to note the contradictions between both teams when inspecting the attack periscope -and that neither of them understood the real functionalities built in it- :hmm:
Interesting clip.

Lots of interesting footage there as well... :hmm:
Thanks for sharing :up:

Thanks Laufen zum Ziel for posting that clip.
Thanks Hitman for posting that link. I've been reading the report and have found several thing I think are interesting.
1) The American team took very fine notes of details in the boat. This makes it easy to compare with The Fleet Type Submarine. These details are also better than anything to be found in 'general' books on submarines.
2) The difference in drag when travelling surfaced and submerged: It takes 180 RPM to maintain 7 knots surfaced, and 257 RPM submerged.
3) "There were apparently no provisions for charging batteries of torpedoes in the tubes." This would mean that the torpedo crew were kept constantly busy rotating torpedoes out for charging.
4) The description of the TDC is very nice. They note that gyro angles were set automatically by the TDC, but also had hand wheels for manual setting.
5) "The deck gun is entirely too low to be of value unless the ship is operating in exceptionally calm water..."
The British report of the capture of U-570 is also highly entertaining. The description of an earlier mishap reads like a bad game of SH3: "...during a crash dive from a suspected British aircraft, she struck a reef and damaged her bows." What's that about not crash-diving in shallow water?
The British report of the boat itself is also highly detailed, including a description of each piece of equipment, right down to individual serial numbers. I've never read anything like these reports before. The description of torpedo firing is much more detailed that the American report, but then they had the boat in their hands the whole time.
"Salvoes are spread by applying a correction to the mean gyro angle and firing with the minimum firing interval." This confirms what we have long discussed: that the 'Salvo' switch merely tells the crew which tubes are to be fired. Tubes are not fired at the same time as in SH3.
The "Zeiss Fixed Eyepiece Periscope" - the attack scope - has 1.5x and 6x magnifications with 38° and 9° fields of view, but the "Watchkeeping Periscope" is described as being 1.54x and 6.1x, with 36° 38' and 8°24' FOV respectively. A small difference, but interesting. Still, this verifies what Hitman has said all along: that the 1x and 4x maginifications in SH3 are totally bogus.
It is interesting to note the contradictions between both teams when inspecting the attack periscope -and that neither of them understood the real functionalities built in it- :hmm:
I'm not sure what you mean by that. Not arguing with your judgement, I just don't understand.
Between the two reports, I think we have something people have asked for from time to time: a description of a Type VII u-boat as fully detailed as the "Fleet Type Submarine" manual; or as detailed as we're going to get.
