The ten-day battle for the Normandy foreshore as seen through the eyes of German and Allied soldiers who fought and died in June 1944.

The battle of D-Day was not decided within 24 hours as suggested by Cornelius Ryan in The Longest Day. It took the allies nine days to dominate the foreshore upon which they landed. D-Day describes how the Allies pierced the Atlantic Wall to the point at which German operational planning accepted it was dealing with an established bridgehead. The battle of Normandy followed.

The book describes how the deception plan achieved a strategic check-mate over the Wehrmacht, enabling eight Allied divisions to come ashore and overwhelm five German divisions in place, despite overwhelming enemy superiority on the Continent of Europe.

The German plan was born of a compromise between those who believed the decisive battle would be fought inland, against those who saw the fundamental importance of defending on the beaches. The much vaunted Atlantic Wall had no depth and sparse coverage in many sectors.

The story of the parachute night and daylight beach assaults is told through the medium of vivid personal veteran accounts, diaries, letters and oral stories. The perspective is given of what it was like to jump from an aeroplane by night in Normandy or assault through obstacle strewn surf at dawn across heavily defended beaches. The tale is also taken up by confused German reactions to scattered Allied parachute descents, which appeared to lack coherence; as also the stunned reaction of German observers gazing from their bunkers at the huge Allied armada, knowing this was no deception.

Local German reserves were decoyed away from beaches awaiting impending assault looking for paratroopers, convinced landings were a feint. Once the scale of the invasion was apparent, Allied air power reduced German counter-measures to impotency. Surviving such air attacks is recounted in graphic detail.

On the American Omaha beach the first and second assault waves were fought to a stand-still. German telephone log extracts bring the landings to life as observed from both sides. At Utah the Americans ripped a seven kilometre hole in the German defences while by evening three British and Canadian divisions were ashore, forcing dispersed German company groups from five to 12 kilometres inland.

The sudden appearance of Allied tanks – Hobart’s ‘Funnies’ – on the foreshore was decisive. Technological surprise contributed much to the success of the invasion. The geographical spread of the assault from sky and sea was unsurpassed historically, therefore beyond rational German intelligence assessment, distracted by deception, to comprehend. Allied air power stymied command and control thereafter and all but broke the Wehrmacht logistic chain.

The battle of D-Day was an Allied success but took nine days to achieve. Village fighting in the hinterland developed into stalemate as the Germans began to match the Allied build up after seven days. Bocage hedgerow terrain proved two-edged, favouring defence but stymieing the mobility sought by both sides and unsuitable for armoured sweeps.

This is a human story. Clinical comparisons of division strengths suggest a missed Allied opportunity, but the human cost to both sides invalidate mathematical equations. The Allies alone suffered 15,000 casualties in the first 48 hours. D-Day vividly describes the battle for the next hedgerow and hill, the fight for survival and comrades. Strategic design was of little consequence to soldiers beset by the terrors of the battlefield. It was the business of generals. Psychological and physical pressures, alongside fear and appalling casualties was to negate the planning process on both sides.

D-Day was won, but set up a battle of attrition to be fought in Normandy.
