I picked up the Sword Beach volume the other day. This is new series published by Alan Sutton in the UK (£14.99 each); they are what the 'Battleground Europe' series should have been. An excellent mix of historical information and battlefield details so you can do a tour - and full of colour photos and coloured maps. Excellent - and will be ideal for any visit to the Normandy battlefields. The volumes on the Orne Bridgehead (6th Airborne) and Sword are out now, with others to follow.
Highly recommended.
See, eg, the page for Sword Beach:
