Excellent book - I like the bit where they require a valve of some description and can't find any. Then they find one propping the mess door open or something?
There are some other excellent 'war' type books I can recommend that really try and tell the story of what these people went through.
The Last Escape is about Allied POW's and Tail End Charlies is about the bomber crews, both written by John Nichol & Tony Rennell.
Fighter Boys is about the Spitfire pilots, written by Patrick Bishop.
Band of Eagles is about the small band of men based on Malta in WWII. It's more fiction based on the truth than the books above, but still a good read. That's written by Frank Barnard.
It's interesting to hear about other people having read these types of book. I always try to read at least one documentary style book for every few fictional books I read. I always get the impression when people see me reading one of these type of books, that I am some kind of war-obsessed geek.
Quite often I will take one on holiday with me - I think a lot of people imagine them to be depressing, but I find them quite uplifting. The things people went through and did, because it was required of them.
