The Destroyers for Bases Agreement was a diplomatic arrangement between the United States and the United Kingdom in 1940, during World War II. In exchange for 50 American destroyers, the UK would grant the US full use of eight naval and air bases along the British coast and in Newfoundland and Bermuda.

At the time, the UK was facing severe shortages in naval resources and was under constant threat from German U-boats. Meanwhile, the US was still officially neutral, but President Franklin D. Roosevelt was eager to provide assistance to the UK without entering the war directly.

The agreement was signed on September 2, 1940, and the US immediately began transferring the destroyers to the UK. In exchange, the US gained access to strategically important bases that would allow them to better protect convoys and patrol the Atlantic.

The Destroyers for Bases Agreement was a crucial step in the US`s eventual entry into World War II. It helped to solidify the US-UK alliance and provided a tangible example of American support for the Allied cause.

Today, the Destroyers for Bases Agreement is remembered as a key moment in the history of US-UK relations and a symbol of the strength of the transatlantic alliance. It also serves as a reminder of the sacrifices made by both nations in the fight against tyranny and oppression.
