Why did the United States establish military bases in Bermuda during World War II?

The United States established military bases in Bermuda during World War II as part of the 1940 Destroyers for Bases agreement. Under this deal, the U.S. provided Great Britain with 50 World War I-era destroyers to help replenish the British fleet, which had suffered significant losses while attempting to secure Atlantic sea routes against Germany.12

In exchange for these vessels, the United States received 99-year leases to establish military installations in Bermuda, Newfoundland, and various locations throughout the Caribbean. These bases were strategically vital for the Allied powers in the Battle of the Atlantic, as they allowed the U.S. to project military power, protect merchant shipping from U-boat attacks, and maintain control over critical Atlantic supply lines.12
