I haven't read the book, but it is well known that Major Brian Urquhart ( now Sir Brian Urquhart) tried to get Browning to amend the plan, inlight of information regarding German troop build up. Browning had him removed on medical grounds. Urquhart is still alive and nearly a centurion! I could never understand why the RAF and Typhoons in particular didn't not deal with the German armour as they had done in Normandy.
