I too am reading a book on the invasion, Sir Max Hastings excellent book “Overlord”.
Just finished reading “Normandiefront: D-Day to St Lo Through German Eyes”. A fascinating account from German soldiers fighting from the other side of the beach and hedgerows. The Germans really never had a chance, despite their tenacity and combat experience. Allied combat mass, logistics, air power and Hitler’s obsession over keeping his panzer divisions oriented on the Pas de Calais made sure of that.
