I just finished read Band of Brigiands by Christy Campbell ISBN 97800072214600
and I must say it is a very comprehensive book on the developement and deployment of the Mk I-V*. The covers a great deal on the men who develpoed the first tanks and all the controversy that surrounded them. I highly reccomend this book. I have no connection with the author and I purchased the book through Amazon.com.
Yes, it seems to have been generally well received John - numerous mentions elsewhere in these pages, also in The Great War Forum - James H liked parts of it and that, together with your recommendation is enough for me, it goes on the "keep an eye out for" list.
