Which key Allied meeting occurred first and had to be held in secret?

Answer 1

The key Allied meeting that occurred first and had to be held in secret was the Atlantic Conference, also known as the Arcadia Conference. It took place in August 1941, with the leaders of the United Kingdom and the United States, Winston Churchill and Franklin D. Roosevelt, meeting to discuss and outline the goals and strategies for the Allied war effort against the Axis powers during World War II. The meeting was held aboard a ship off the coast of Newfoundland and was kept secret to avoid alarming the public and enemy forces about the discussions taking place regarding war strategies.
