Eagles and Bulldogs in Normandy 1944 - by Michael Reynolds

In this book, we learn about the agonies suffered by soldiers of two different countries who were fighting for the same objective.  Americans were pushing forward on Omaha Beach while Brits were doing the same thing at Sword. 

Their combined casualties were astronomical.

The publisher tells us more about their sacrifices:

This is the story of the two divisions: the American 29th and the British 3rd. After describing the agonies suffered by the Americans on Omaha, and the difficulties that face the British in overcoming strong points at Sword Beach on D-Day, the author traces both divisions as they try to break through the German defences.

It was to take the GI's nearly six weeks to reach their objective, whilst the Tommies were forced into a concurrent holding operation redolent of the trench warfare experience of World War One.  The main part of Caen, the central communication point and respective objective was eventually captured on the 9th July, but by this point, the two Allied divisions had suffered more than 10,000 casualties, and several thousands of French civilians had been killed.
