Operation Accumulator was an Allied naval operation near the Channel Islands on the night of 12/13 June 1944, in support of Operation Overlord, the invasion of France.
As part of Operation Fortitude, a series of deception operations had been used to divert attention from the Allied landings by suggesting that a second invasion force was still waiting to land. This caused the defenders to divert their forces from the fighting in Normandy, holding them in reserve for an invasion in the Pas de Calais, to the east.
Some days after the initial landings, it was decided to mount a smaller operation to simulate a follow-up landing force heading for Granville, at the western side of the Cotentin Peninsula. The desired effect would be to force the German command to pull units from the front line and redeploy them to protect the western coast.
The plan was for two Royal Canadian Navy destroyers, Haida and Huron, to make a series of fake radio transmissions, which would be intercepted. The beginning of the operation went smoothly, with the two ships signalling that the invasion fleet had been delayed by engine problems, and giving a revised plan. However, the radios on the Haida broke down, forcing the Huron to continue alone; the two ships were also spotted by an Allied reconnaissance plane, which radioed back that it had found "unidentified warships".
The operation was a failure; whilst the signals were made, there was no reaction from the German force. This may have been helped by the Allied air report - the pilot would have been informed - and by a lack of any corroborating evidence; for example, there was no attempt at spoofing radar signals, as had been carried out for the main invasion by Operation Glimmer and Operation Taxable.
Operation Fortitude was the code name for a World War II military deception employed by the Allied nations as part of an overall deception strategy during the build-up to the 1944 Normandy landings. Fortitude was divided into two sub-plans, North and South, with the aim of misleading the German High Command as to the location of the invasion.
Operation Torch was an Allied invasion of French North Africa during the Second World War. Torch was a compromise operation that met the British objective of securing victory in North Africa while allowing American armed forces the opportunity to engage in the fight against Nazi Germany on a limited scale. It was the first mass involvement of US troops in the European–North African Theatre, and saw the first major airborne assault carried out by the United States.
Operation Bodyguard was the code name for a World War II deception strategy employed by the Allied states before the 1944 invasion of northwest Europe. Bodyguard set out an overall stratagem for misleading the Oberkommando der Wehrmacht as to the time and place of the invasion. Planning for Bodyguard was started in 1943 by the London Controlling Section, a department of the war cabinet. They produced a draft strategy, referred to as Plan Jael, which was presented to leaders at the Tehran Conference in late November and, despite scepticism due to the failure of earlier deception strategy, approved on 6 December 1943.
Operation Dragoon was the code name for the landing operation of the Allied invasion of Provence on 15 August 1944. The operation was initially planned to be executed in conjunction with Operation Overlord, the Allied landing in Normandy, but the lack of available resources led to a cancellation of the second landing. By July 1944 the landing was reconsidered, as the clogged-up ports in Normandy did not have the capacity to adequately supply the Allied forces. Concurrently, the French High Command pushed for a revival of the operation that would include large numbers of French troops. As a result, the operation was finally approved in July to be executed in August.
The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of France and laid the foundations of the Allied victory on the Western Front.
Operation Jubilee or the Dieppe Raid was an Allied amphibious attack on the German-occupied port of Dieppe in northern France, during the Second World War. Over 6,050 infantry, predominantly Canadian, supported by a regiment of tanks, were put ashore from a naval force operating under protection of Royal Air Force (RAF) fighters.
Operation Avalanche was the codename for the Allied landings near the port of Salerno, executed on 9 September 1943, part of the Allied invasion of Italy during World War II. The Italians withdrew from the war the day before the invasion, but the Allies landed in an area defended by German troops. Planned under the name Top Hat, it was supported by the deception plan Operation Boardman.
Operation Slapstick was the code name for a British landing from the sea at the Italian port of Taranto during the Second World War. The operation, one of three landings during the Allied invasion of Italy in September 1943, was undertaken by airborne troops of the British 1st Airborne Division, commanded by Major-General George Hopkinson.
HMCS Haida is a Tribal-class destroyer that served in the Royal Canadian Navy (RCN) from 1943 to 1963, participating in World War II and the Korean War. She was named for the Haida people.
The Tribal class, or Afridi class, were a class of destroyers built for the Royal Navy, Royal Canadian Navy and Royal Australian Navy that saw service in World War II. Originally conceived during design studies for a light fleet cruiser, the Tribals evolved into fast, powerful destroyers, with greater emphasis on guns over torpedoes than previous destroyers, in response to new designs by Japan, Italy, and Germany. The Tribals were well admired by their crews and the public when they were in service due to their power, often becoming symbols of prestige while in service.
Operation Ironside was a Second World War military deception undertaken by the Allies in 1944. It formed part of Operation Bodyguard, a broad strategic deception plan instigated by the Allies throughout the year to help cover the June 1944 invasion of Normandy. Ironside supported the overall deception by suggesting to the Germans that the Allies would subsequently land along the Bay of Biscay. It complemented efforts to deceive the Germans into believing that the Allies would also land in southern France at this time. Bordeaux was an important port for the German war effort and had already been a target of commando raids two years earlier. Ironside intended to play on German fears of an invasion in the region, with the aim of tying down defensive forces following Operation Overlord in June 1944.
Operation Zeppelin was a major military deception operation run by the British during the Second World War. It formed part of Operation Bodyguard, the cover plan for the invasion of Normandy in 1944, and was intended to mislead German intelligence as to the Allied invasion plans in the Mediterranean theatre that year. The operation was planned by 'A' Force and implemented by means of visual deception and misinformation.
Operation Titanic was a series of military deceptions carried out by the Allied Nations during the Second World War. The operation formed part of Operation Bodyguard, the cover plan for the Normandy landings in 1944. Titanic was carried out on 5–6 June 1944 by the Royal Air Force and the Special Air Service. The objective of the operation was to drop 500 dummy parachutists in places other than the real Normandy drop zones, to deceive the German defenders into believing that a large force had landed, drawing their troops away from the beachheads and strategic sites such as Caen.
Operation Overlord was the codename for the Battle of Normandy, the Allied operation that launched the successful invasion of German-occupied Western Europe during World War II. The operation was launched on 6 June 1944 (D-Day) with the Normandy landings. A 1,200-plane airborne assault preceded an amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August.
Vice Admiral Henry George DeWolf was a Canadian naval officer who was famous as the first commander of HMCS Haida during the Second World War.
Operations Taxable, Glimmer and Big Drum were tactical military deceptions conducted on 6 June 1944 in support of the Allied landings in Normandy. The operations formed the naval component of Operation Bodyguard, a wider series of tactical and strategic deceptions surrounding the invasion.
Operation Cockade was a series of deception operations designed to alleviate German pressure on Allied operations in Sicily and on the Soviets on the Eastern Front by feinting various attacks into Western Europe during World War II. The Allies hoped to use Cockade to force the Luftwaffe into a massive air battle with the Royal Air Force and U.S. Eighth Air Force to give the Allies air superiority over Western Europe. Cockade involved three deception operations: Operation Starkey, Operation Wadham, and Operation Tindall. Operation Starkey was set to occur in early September, Operation Tindall in mid-September, and Operation Wadham in late September 1943.
The invasion of Elba, codenamed Operation Brassard, was part of the Italian campaign during the Second World War. The invasion was carried out between 17–19 June 1944 by Free French Forces supported by British and American ships and aircraft.
R Force was a British deception force during World War II that consisted of armoured vehicles, field engineers and a wireless unit. During Operation Fortitude it attempted to exaggerate the strength of Allied forces in Britain, and deceive German intelligence about Allied intentions. Later it performed a similar role during the fighting in Western Europe in 1944–45. It was commanded by Lieutenant Colonel David Strangeways.
Operation Ferdinand was a military deception employed by the Allies during the Second World War. It formed part of Operation Bodyguard, a major strategic deception intended to misdirect and confuse German high command about Allied invasion plans during 1944. Ferdinand consisted of strategic and tactical deceptions intended to draw attention away from the Operation Dragoon landing areas in southern France by threatening an invasion of Genoa in Italy. Planned by Eugene Sweeney in June and July 1944 and operated until early September, it has been described as "quite the most successful of 'A' Force's strategic deceptions". It helped the Allies achieve complete tactical surprise in their landings and pinned down German troops in the Genoa region until late July.
