One of the things discussed in the mid Atlantic in the early days of WW2 in a meeting between Roosevelt and Churchill was the colonies of Britain. Roosevelt and the US frowned on colonialism and believed it had no place in the modern world .Churchill was on that ship to plead for US aid. Even a hard nosed old bulldog knows when he's over a barrel and part of the agreement was that Britain would begin to dismantle its Empire after the war.

The meeting held in 1945 between Winston Churchill, Joseph Stalin, and Franklin D. Roosevelt was the Yalta Conference. This pivotal meeting took place from February 4 to 11 and aimed to discuss the post-World War II reorganization of Europe and the future of nations liberated from Nazi occupation. Key topics included the re-establishment of countries, the division of Germany, and the formation of the United Nations. The conference set the stage for the Cold War dynamics that would follow.

If you are referring to the Conference between Roosevelt and Churchill in August 1941, at Ship Harbour in Placentia Bay, Newfoundland, which produced the Atlantic Charter, Churchill arrived on the HMS Prince of Wales. The HMS Hood had been sunk the preceding May by the Bismarck. The Prince of Wales would be lost, along with HMS Repulse, the day after Pearl Harbor, to Japanese aircraft based in Saigon. Roosevelt arrived aboard a heavy "Treaty" cruiser, the USS Augusta. This was the first personal meeting of Churchill and FDR.
The 1943 meeting in Casablanca between President Franklin D. Roosevelt and Prime Minister Winston Churchill resulted in the decision to pursue the strategy of "unconditional surrender" for Axis powers, which aimed to ensure that they would not negotiate separate peace agreements. The leaders also agreed to increase military pressure on Germany through the invasion of Italy and to continue support for Allied forces in the Pacific. This meeting solidified their cooperative approach and set the stage for future Allied operations during World War II.
The "Casablanca Meeting" in January 1943 between Roosevelt and Churchill and their Combined Chiefs of Staff germinated the idea of D-Day. Their appointment of Gen Eisenhower as Supreme Commander in December 1943 brought it into effect.
