John Buckley 
British Armour in the Normandy Campaign [PDF ebook] 

The popular perception of the performance of British armour in the Normandy campaign of 1944 is one of failure and frustration. Despite overwhelming superiority in numbers, Montgomery’s repeated efforts to employ his armour in an offensive manner ended in a disappointing stalemate. Explanation of these and other humiliating failures has centred predominantly on the shortcomings of the tanks employed by British formations. This new study by John Buckley challenges the standard view of Normandy as a failure for British armour by analysing the reality and level of the supposed failure and the causes behind it.
