On this 78th anniversary of the D-Day invasion of Nazi-occupied France, military historian Cathal Nolan discusses the chaos and confusion that prevailed over the early hours of the largest amphibious assault in history. Yet despite mishaps and setbacks that are unavoidable in major combat, the Allied forces captured the five beaches along the Normandy coast by the end of June 6, 1944. The Germans missed their chance to repel the invaders, but was it a decisive battle on the road to victory in the Second World War? Nolan argues decisive battles are almost always a mirage.
