It was on this pivotal day in 1943 that the very first Quebec Conference was held. Codenamed 'Quadrant', the meeting brought together the British, Canadian and United States governments for top secret military discussions and decisions about WWII. Held in Quebec City at the Citadelle and Château Frontenac, the conference began on August 17 and came to a close a week later on August 24. With Winston Churchill, Franklin D. Roosevelt and William Lyon Mackenzie King in attendance, the three allies discussed the invasion of France, upping the bombing offensive against Germany and the removal of Italy from the alliance of Axis Powers followed by a subsequent occupation amongst many other points which were to change the course of the war drastically. In addition, Churchill and Roosevelt also put their minds together and secretly signed the Quebec Agreement to share nuclear technology and knowledge making this a particularly historic day never to be forgotten.
