This is the comprehensive review of the Allied campaign in Normandy from primary sources, including extensive eyewitness accounts, Allied plans, intelligence reports, historical documents and combat reports.

The Allied campaign in Normandy is one of the most spectacular unusual military campaigns ever undertaken. The successful implementation of the Normandy Campaign required a vast assembly of men and machines, detailed planning at every level and raw courage to carry out the plans.

What is astonishing is that the entire operation proceeded almost exactly according to the plans laid down by the Allied High Command. The River Seine was reached by D-Day plus 90 and Paris was soon in Allied hands.
