Unlike any other service chief in Great Britain at the time, such as Sir Alan Brooke, Chief of the Imperial General Staff (CIGS), the First Sea Lord was both the professional head of the Royal Navy and the commanding officer of the entire fleet. Pound could, and did, go over the heads of Admirals on the scene in their flagships and even over the head of the C-in-C, Home Fleet, the most powerful fleet in the Navy usually kept close to home to defend the British Isles. The commander of the Home Fleet was always an Admiral of the Fleet as well.
In September of 1943, Pound had a stroke in Washington, DC while accompanying Prime Minister Churchill to a meeting with President Roosevelt. Pound resigned the next day and died a month later in London.
