Among the Allied troops storming ashore in the Dieppe landing on that fateful morning of 19 August 1942 was a young Royal Air Force sergeant, Jack Nissenthall. His mission: to find out how advanced German radar was. A radar expert himself, he knew so much about the British installations that he carried cyanide to take in case he was taken prisoner; as well, the eleven men of the South Saskatchewan Regiment who were his guard had orders to shoot to kill, should he fall into German hands. But in the blood-bath that followed, Sergeant Nissenthall saw all but one of his eleven-man escort die under enemy fire. The survivor, Leslie Thrussell, now lives in Moose Jaw, Saskatchewan. All these years later, the former sergeant, now Jack Nissen, has an electronics business in Thornhill, Ontario, just north of Toronto, but he’s never forgotten that bitter day.
Charlie Sawden, Graham Mavor, Silver Stewart and John Morrison. These are the names of young Canadians who perished on a gloriously sunny day in August 1942. Their average age was twenty-one. They had volunteered for a military operation they were told would bring relief and eventual victory to the hard-pressed Allies in the war against Hitler.
The Second World War was three years old, yet despite the morale-boosting propaganda we had yet to win a decisive battle anywhere. Each month we lost almost a million tons of shipping to German U-boats; food line-ups in Britain became longer and longer, individual rations smaller and smaller.
The Japanese had taken Singapore, Hong Kong, a large portion of China, the Philippines and had invaded India. The Germans were in Moscow’s suburbs and their armies were angling south to the oilfields of the Caucasus and the Middle East. In June, Tobruk had fallen and General Erwin Rommel’s armies had at last entered Egypt. Mussolini prepared to lead the victory parade into Cairo on a beautiful white stallion.
There is little doubt that in mid-1942 the French had every reason to believe the main fighting was over and the Axis powers, Germany, Italy and Japan, had conquered. It was during this period that men of the Canadian 2nd Division prepared for a reconnaissance in force on the northern French port of Dieppe. With no victories to their credit and their military commanders still discredited after the ejection from France at Dunkirk two years earlier, the Allied commanders were striving to set up a new set of military guidelines and disciplines for the hoped-for return to the mainland.
Hitler and propaganda minister Josef Goebbels had boasted of the huge concrete emplacements and massive guns along the French coast to repel invaders. The Wehrmacht, the German Armed Forces, was a highly successful professional; the Allies the apprentices. Nevertheless, we were confronted with the knowledge that the war would never be won until we returned to the continent and defeated the Germans occupying France. It also would have to be done before the battle-hardened German Army returned from the Soviet Union, which in 1942 seemed on the verge of defeat.
A powerful, probing military reconnaissance was required to allow us to verify theories and develop the naval, army, air and communications equipment required when we stormed the German defenses on the return to France. An army of heroes was required—tough troops of high morale to carry out the most hazardous of war operations, a massive commando raid on German-occupied France.
The raid eventually took place on 19 August 1942 and, as is well known, it was a bloody and devastating confrontation. By twelve o’clock that day one thousand Canadians had been killed and more than one thousand others captured. The Royal Air Force lost 105 aircraft, more than twice the number lost in any big battle during the Battle of Britain. Together with the large material losses, the traumatic shock of the disaster rammed home the idiocy of those who insisted the return to the continent would be a “piece of cake.”
Over the years many writers have described the Dieppe raid as utterly useless and a debacle. Every military man knows a reconnaissance or scouting expedition, however small, always yields useful intelligence. On this raid, in which I took part as an agent of the British Air Ministry, we gleaned a storehouse of strategic information which allowed us to set up a whole series of undreamed of military disciplines that are still valid today.
Immediately after the raid, Lord Mountbatten initiated hard-hitting discussions at his headquarters in Richmond Ter-race, Whitehall. Participants in the raid, regardless of rank, were assembled and ordered to criticize every aspect of the operation. From these sessions plans emerged that facilitated the invasion of Normandy.
In the early hours of 6 June 1944, seven thousand vessels took up positions in the storm-swept seas, under the very noses of dozens of superb enemy radars, without a single shot being fired. The silence of the German guns has puzzled writers and historians over the years, for the German radar-controlled guns were known for their deadly accuracy. They could hit a rowboat at ten miles.
Was it really a miracle and sheer good luck that got our armies ashore in exactly the right places and times on that historic occasion? The truth is that the landings were the culmination of two years of top secret hard work, planning, production and subterfuge initiated by Lord Mountbatten immediately after the sessions that followed the Dieppe raid. Naval, army and communications equipment, together with a mass of radar countermeasure devices, were conceived, tested and mass produced for landings that preceded the big target, the Normandy beaches.
When the Canadians landed at Dieppe, they were stymied by a high seawall which ran the length of the beach and which the Churchill tanks could not scale. For the most part, the thirty tanks had to lay back on the water line and exchange fire with entrenched German guns until they were knocked out.
Canadian engineers could not clear the land mines or penetrate the beach defenses because they could not survive under the withering fire of the German gunners in the beachfront hotels. Lord Mountbatten swore that would never happen again.
In 1944 the situation was different: there were hundreds of specialized tanks and aids to invasion that gave us the edge in the first few hours of D-Day.
There were tanks that swam ashore with the troops to ensure that flesh was not pitted against steel. There were armored “flails” which exploded mines in the path of advancing men. There were tanks to lay carpets of coir matting over the sand and shale to avoid the repetition of another Dieppe fiasco, when our tank tracks were wrecked by shale pebbles. Other armored vehicles could toss a huge stack of explosive at a pillbox and demolish it instantly. Churchill tanks, with their superstructures removed, overcame what had been a major obstacle at Dieppe: they would position themselves against a seawall and allow their companions to ride up and over the top. Other tanks had booms to set up temporary bridges which allowed their companions to traverse tank traps and even ride up the base of a cliff. Flamethrower tanks developed at Fort Suffield, Alberta, speeded up the disposal of other strongpoints.
This strange assortment of armored vehicles was developed between Dieppe and D-Day as part of a whole series of aids to invasion that played a large part in the successful landings on the Canadian and British beaches. The Americans, who elected not to use this equipment, suffered a far worse disaster at Omaha Beach on D-Day than had the Canadians at Dieppe. The incredible D-Day naval navigation was not due to normal navigational skill, but the use for the first time of a device developed by and for the RAF. It was a precision air navigational aid known to thousands of Canadian airmen as GEE. Its accuracy was such that a bomber could check its position within fifty yards when 200 miles inside Germany. When used shipboard in the English Channel for sweeping mines and marking the areas, its accuracy was phenomenal. All navigation and position-taking in those dark stormy seas of D-Day were carried out by naval adaptation of the Goon Box, as GEE was affectionately called. Due to its universal use during the invasion, some people feel G-Day would have been more apt than D-Day.
All this wonderful equipment, training and expertise would have been useless if the hundreds of German guns had gone into action on the enormous concentration of ships, some just a mile or two off the coast. A field marshal by then, Rommel made an order that day to the gun crews that had been to the point. “The enemy must be annihilated before he reaches a battlefield. We must stop him in the water, not only delaying him, but by destroying all his equipment while it is still afloat.”
A method had to be found to get the ships close to shore during the darkness without being pulverized by the hundreds of radar-controlled guns. It was the Director-General of Signals and Radar for the RAF, Sir Victor Tait of Winnipeg, who masterminded a plan to dupe the Germans on a once-only basis. It was he who coordinated the ultra-secret stratagems and radar countermeasures.
It was Sir Victor who sent me to Dieppe in 1942 to verify that the Freya radar had become precision radar. Once he had verified this, he ordered the mass production of radar countermeasure equipment. This ultra-secret equipment was codenamed Mandrel. At the throw of a switch, a curtain could be drawn across a Freya radar screen. After some flying tests two months after Dieppe, it was given limited secret service. High-powered Mandrel transmitters were mass produced for installation on two hundred ships for D-Day.
It was Dieppe and the impetus it gave the development of special devices that supplied us the key to victory. Without that 1942 reconnaissance, we would never have developed the systems that enabled us to land safely in Normandy in 1944.
