This is an incredible book - I was inspired to read it by a throw-away comment by current American Sec of Defence James Mattis (USMC, notable for his "mad-dog" given nickname, his "chaos" self-chosen callsign, and love of Marcus Aurelius) about how the book inspired him and I was not disappointed. This story of planning, logistics and bravery both collective and individual by soldiers & sailors in astoundingly audacious circumstances reads like a thriller, keeping me on the edge of my seat with its relatively small cast of characters all fully fleshed out, the extensive preparation explained down to every detail (when destroying lots of identical industrial machinery, put the charges on the same part of each machine, so that the remnants can't be cannibalised to make a few work afterwards) and the action itself described with extensive maps and narrative flair that "put me there" with a group of highly motivated, expert and brave heroes. My appreciation of the St Nazaire raid (which I knew about as a general fan of WW2 history) was deepened and expanded by this great work, and I can see how a modern soldier like James Mattis could draw lessons about it even today.
