I'm just going to offer some initial thoughts at the moment, as there is a lot of criticism surrounding this book and its accuracy. I need to read more to fully understand those arguments, so I will refrain from a full review at this time.
I found the book an easy read, but I think part of this is because I already had much of the political background from slogging through Hastings & Jenkins "The Battle for the Falklands".
Bicheno is quite outspoken in his views on the British Public Service and also on the Argentine regime. In addition, he is highly critical of 5 Brigade command and of "H" Jones.
The book contains a wealth of maps and details of the battles, which appears to make it an invaluable reference for those planning table-top scenarios, but it is this very information which is called into question by some commentators, so until my research is more complete, I won't offer a full recommendation either way at this time.
My next target is Martin Middlebrook's "The Fight for the Malvinas", to try to cement more Argentine information before I focus on more accounts from the British side.
