Landing on the beaches at Normandy was just the start of liberating Europe. The Allies needed to supply a long campaign and there were no harbours on the Normandy coast where they could berth their cargo ships.
The lack of ports meant the Germans viewed Normandy as an unlikely spot for invasion, they believed the attack would come at Calais. The Allies did their best to convince them this was the case - but they still needed to come up with a creative engineering solution for docking their supply ships.
George Batts from Maidstone was in the Royal Engineers and landed on Gold Beach on D-Day. He later helped piece together the giant artificial harbour the Allies towed to Arromanches - one of the two Mulberry harbours.
Five years ago he was awarded the Legion d'Honnour, France's highest military honour. He is also the General Secretary of the Normandy Veterans Association. He has been speaking to Meridian about the invasion and the logistics required to make it work.
