At 6 p.m. on August 17, 1943, Winston Churchill along with the Earl of Athlone, the Governor-General of Canada; Prime Minister William Lyon Mackenzie King; and other officials met Franklin Roosevelt’s train as it arrived at Wolfe’s Cove train station in Quebec City. Churchill had arrived in North America earlier in the month for the QUADRANT conference with the American president. During the conference, the military staffs were at the Chateau Frontenac, while the prime minister and president were headquartered at the Citadel, which was the summer residence of the Governor General of Canada. The two plenary sessions of the conference were also held at the Citadel. The meetings of the Combined Chiefs of Staff had begun at Quebec on August 14, 1943.

Churchill, Roosevelt, and the other officials made the two mile drive to the Citadel from the station along a route that was lined with thousands of cheering Canadians. At the Citadel honors were rendered by the Royal Marines, the Canadian military, and the Royal Canadian Mounted Police band. The U.S. anthem was played as the American flag was raised alongside the Canadian and British flags. After the ceremony official photographs were taken. At 6:30 p.m. the Governor-General and his spouse, Her Highness Princess Alice, hosted a small cocktail party at his residence in the Citadel to mark Roosevelt’s arrival. At the party Churchill, Roosevelt, General Alan Brooke, and Admiral William Leahy discussed the cable to be sent to General Dwight Eisenhower about the proposals received from Marshal Badoglio, the Italian prime minister. A large dinner party then followed. It was hosted by the Athlones in honor of the British prime minister and American president. At the dinner, several movies, including Disney cartoons, were shown in the Citadel’s ballroom. The dinner dispersed at 11:30 p.m., after which Churchill and Roosevelt held discussions until a late hour.

During the day Churchill had received a cable from General Harold Alexander announcing that the last German soldiers had been hurled from the island of Sicily. Also, that day Churchill prepared his own paper on the strategic direction of the war, including operations in Italy and proposed operations in Sumatra.
