Quebec Conference, 1943

The First Quebec Conference (codenamed "QUADRANT") was a highly secret military conference held during World War II between the British, Canadian and United States governments. The conference was held in Quebec City, August 17, 1943 – August 24, 1943. It took place at the Citadelle and at the Château Frontenac. The chief representatives were Winston Churchill and Franklin D. Roosevelt, hosted by the Canadian Prime Minister, William Lyon Mackenzie King. Although Churchill suggested that Mackenzie King be involved in all discussions, Roosevelt vetoed the idea. As a result, Mackenzie King's hospitality was almost purely for ceremonial purposes. Joseph Stalin, leader of the Soviet Union, had been invited to join the conference, but he did not attend for military reasons.

The Allies agreed to begin discussions for the planning of the invasion of France, codenamed Operation Overlord, in a secret report by the Combined Chiefs of Staff. It was agreed that Overlord would commence on May 1, 1944, but this was subsequently disregarded and a later date was finalised. However, Overlord was not the only option; for example, Operation Jupiter remained a strong possibility had the Germans proved too powerful on the French coast. In the Mediterranean (a theatre on which Churchill was very keen) they resolved to concentrate more force to remove Italy from the alliance of Axis powers and to occupy it along with Corsica. Churchill and Roosevelt made it clear that they would only accept unconditional surrender from Italy, with there to be a complete and immediate cessation of fighting. News came through of the fall of Sicily to Allied forces, an invasion that had taken just 38 days. It was then decided that an invasion of Italy would begin on September 3, 1943. However, an armistice was signed that same day, which officially put Italy out of the war.
