Military history of Gibraltar during World War II

The military history of Gibraltar during World War II exemplifies Gibraltar's position as a British fortress from the early-18th century onwards and as a vital factor in British military strategy, both as a foothold on the continent of Europe, and as a bastion of British sea power. During World War II, Gibraltar served a vital role in both the Atlantic Theatre and the Mediterranean Theatre, controlling virtually all naval traffic moving between the Mediterranean Sea and the Atlantic Ocean.
