Almost everyone at every level was acutely conscious of taking part in a great historical event. Headquarters of the American V Corps heading for Omaha beach recorded in its war diary, ‘The attempt to do what had been contemplated by all the great military leaders of modern European History — a cross channel invasion — was about to commence.’
The main question in most minds was whether the Germans already knew what was afoot and would be waiting for them. Planners of Operation Neptune, the cross-Channel phase of Overlord, had spent months considering possible threats to the invasion fleets: submarines, mines, E-boats, radar and the Luftwaffe. Every precaution was taken.
Mosquito squadrons were patrolling the French coast all night, ready to down any German aircraft which might sight the approaching fleets. Aircraft equipped for radio counter-measures were also aloft to jam the frequencies used by German night-fighters. Large-scale radar-jamming operations were carried out by British and American aircraft over the Channel. And for several weeks, rocket-firing Typhoons had attacked German radar sites all along the Channel coast from the Netherlands to Brittany.
In Operation Taxable, Lancaster bombers of 617 Squadron dropped ‘window’, aluminium strips to simulate on radar screens an invasion convoy approaching the coast at Cap d’Antifer, north-east of Le Havre. This was assisted by a naval deception using motor launches and torpedo boats towing reflector balloons, which would look like large ships on radar. A similar deception plan, Operation Glimmer, consisted of Stirling bombers dropping ‘window’ opposite Boulogne. Mines were also dropped round Cap d’Antifer.
One of Admiral Ramsay’s greatest concerns was a mass attack on the invasion fleet by German U-boats from their bases in Brittany. Naval anti-submarine forces were deployed, but the main task of covering the south-western approaches fell to 19 Group of Coastal Command mainly flying B-24 Liberators and Sunderland flying boats. The group included one Czech, one Polish, one New Zealander, two Australian and three Canadian squadrons. Even the RAF’s own 224 Squadron was a mixed bag of nationalities, with 137 Britons, forty-four Canadians, thirty-three Anzacs, two Americans, a Swiss, a Chilean, a South African and a Brazilian.
Their crews faced long missions day and night, constantly patrolling the western Channel in box patterns from southern Ireland down to the Brest peninsula. When their radar picked out any submarine on the surface, the aircraft would dive, the front gunner trying to kill and wound as many as possible on the conning tower to impede a crash dive, then the aimer would release the depth charges. In Operation Cork, aircraft from 19 Group attacked forty submarines. One of 224 Squadron’s Liberators piloted by the twenty-one-year-old Canadian, Flying Officer Ken Moore, made naval history by sinking two U-boats within twenty-two minutes on the night of 7 June. To the embarrassment of Gro?admiral Karl Donitz and the high command of the Kriegsmarine, not a single U-boat penetrated the English Channel. Other Allied aircraft attacked German destroyers to prevent them from engaging the invasion fleet. Only fast German E-boats and later midget submarines managed to inflict any losses.
On board the landing ships, soldiers whiled away the time. Some tried to sleep, some attempted to learn a little French from their phrase books, some read their Bibles. Many attended improvised church services, finding comfort in religion. On the British ship

The men of the 116th Infantry Regiment heading for Omaha found it hard to forget the address of their commanding officer, Colonel Charles D. Canham. He had predicted that two out of three of them would never return home. He finished off his warning in a pronounced southern drawl: ‘Anyone who has

On more than 100 airfields in England, bomber pilots from both the RAF and the USAAC were being roused from their beds for breakfast and an early briefing. Most guessed that something big was up, but they were not sure what. The pilots of the American 388th Bomber Group at Thetford were apparently unprepared for the ‘dramatic announcement’ of the briefing officer on the platform. ‘As he drew back the white sheet that covered the operational map, he said, “Gentlemen, today the Allies invade the Continent”. Pandemonium broke loose as the briefing room exploded with cheers and whistles and shouts.’ He then went on to tell them that ‘everything in the Eighth Air Force that could fly’ would be taking off that morning. The bomb groups, once assembled in the air, would stretch for miles and miles as they streamed over towards their targets on the Normandy coast. Formation and fire discipline was vital. ‘Any individual plane flying in the opposite direction, that is, against traffic, once we left the coast of England, would be shot down.’
The reaction at British briefings appears to have been more subdued, mainly out of awe at the magnitude of the whole operation. ‘The preparations were staggering,’ wrote Desmond Scott, a New Zealander who commanded a wing of four Typhoon squadrons. ‘The airborne assaults, the quantity and variety of shipping, the number of army divisions, the tremendous weight of the air offensive. The scale and the precision of it all made our past efforts look insignificant. When the briefing was over there was no conversation, no laughter. No one lingered and we filed out as though we were leaving church. Expressions remained solemn. The task ahead outweighed all our previous experiences and sent a shiver down the spine.’
The RAF was putting up a maximum effort that night. Apart from the aircraft on deception and airborne missions, 1,000 bombers took off to attack ten coastal batteries during darkness with more than 5,000 tons of bombs. Spitfire squadrons scrambled to provide air cover over the beaches, along with American P-38 Lightnings. Their task was to prevent any Luftwaffe incursions over the invasion area, while the longer-range Mustangs would
