During the First World War, Plymouth, Devonport and Stonehouse contained between them the Royal Dockyard, Royal Naval Barracks (known as H.M.S. Vivid), the Royal Marine Barracks of the Plymouth Division, and naval and military hospitals. For the duration of the war, Devonport was made headquarters of the Auxiliary Patrol Area.
Plymouth was a naval station second only to Portsmouth during the Second World War. Devonport was also an important military station and there was a R.A.F station at Mount Batten, opposite Plymouth.
