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 defenses.
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.
