Operation Jubilee or the Dieppe Raid (19 August 1942) 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. The port was to be captured and held for a short period, to test the feasibility of a landing and to gather intelligence. German coastal defences, port structures and important buildings were to be demolished. The raid was intended to boost Allied morale, demonstrate the commitment of the United Kingdom to re-open the Western Front and support the Soviet Union, fighting on the Eastern Front. Aerial and naval support was insufficient to enable the ground forces to achieve their objectives; the tanks were trapped on the beach and the infantry was largely prevented from entering the town by obstacles and German fire. After less than six hours, mounting casualties forced a retreat. The operation was a fiasco in which only one landing force achieved its objective and some intelligence including electronic intelligence was gathered. Within ten hours, 3,623 of the 6,086 men who landed had been killed, wounded or became prisoners of war. The Luftwaffe made a maximum effort against the landing as the RAF had expected, but the RAF lost 106 aircraft (at least 32 to anti-aircraft fire or accidents) against 48 German losses. The Royal Navy lost 33 landing craft and a destroyer. Both sides learned important lessons regarding coastal assaults. The Allies learned lessons that influenced the success of the D-Day landings. Artificial harbours were declared crucial, tanks were adapted specifically for beaches, a new integrated tactical air force strengthened ground support, and capturing a major port at the outset was no longer seen as a priority. Churchill and Mountbatten both claimed that these lessons had outweighed the cost.

Dieppe

Dieppe (djɛp; Norman: Dgieppe) is a coastal commune in the Seine-Maritime department, Normandy, northern France. Dieppe is a seaport on the English Channel at the mouth of the river Arques. A regular ferry service runs to Newhaven in England. Famous for its scallops, Dieppe also has a popular pebbled beach, a 15th-century castle and the churches of Saint-Jacques and Saint-Remi. The mouth of the river Scie lies at Hautot-sur-Mer, directly to the west of Dieppe. The inhabitants of the town of Dieppe are called Dieppois (m) and Dieppoise (f) in French.

Amphibious warfare

Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles.

Mulberry harbour

Mulberry harbours were two temporary portable harbours developed by the British Admiralty and War Office during the Second World War to facilitate the rapid offloading of cargo onto beaches during the Allied invasion of Normandy in June 1944. Designed in 1942 and then built in under a year in great secrecy, within hours of the Allies successfully creating beachheads following D-Day, sections of the two prefabricated harbours and old ships, to be sunk to create breakwaters, were being towed across the English Channel from southern England and placed in position off Omaha Beach (Mulberry "A") and Gold Beach (Mulberry "B").
