I posted this in a different thread, but I'll post it here too.
My wife and I just finished watching an excellent mini-series on YouTube on how the British developed a method to defeat the U-Boats in WWII by using war games. The series is about a British unit named the Western Approaches Tactical Unit (WATU). WATU is led by
Captain Gilbert Roberts. He employs women from the
Women's Royal Naval Service (Wrens) as the men sent to him are inadequate for the job. Captain Roberts and the Wrens developed a way to analyze U-Boat tactics and then how to stop them.
The series is a documentary with 7 or 8 historians describing different aspects of the battle and then actors portraying the British and Germans act out important scenes. It is well made and we learned a lot about how this unit stopped the U-Boats from starving Britain into surrender. The Wrens made a huge contribution and never received the credit for what they did.
The series is also available for rent on Amazon Prime under the name War Gamers. Be aware that the name of the series and the episode titles are different on Amazon than they are on YouTube.
The YouTube channel is War Stories. There are six episodes about 50 minutes each.
Here are the titles in order:
1) How Nazi U-Boats Nearly Starved Britain Into Surrender
2) Kretschmer: The Hunt For Nazi Germany's Deadliest U-Boat Ace
3) How Britain Countered Nazi Germany's U-Boat Tactics
4) Operation Raspberry: How The Allies Turned German U-Boat Tactics Against Them
5) Battle Of The Atlantic: How Admiral Dönitz Was Outwitted By British Commanders
6) How Britain Finally Won The Battle Of The Atlantic
