Commander-in-Chief, Portsmouth

The Command extended along the south coast from Newhaven in East Sussex to Portland in Dorset.[2] In 1889 the Commander-in-Chief took HMS Victory as his Flagship.[3]

Admiralty House, HMNB Portsmouth

In the late 18th century port admirals began to reside ashore, rather than on board their flagships; the Commander-in-Chief, Portsmouth was provided with a large house at 111 High Street, which was renamed Admiralty House (and which had formerly been home to the Mayor of Portsmouth).[4] In the 1830s Admiralty House was sold to the War Office (as Government House, it went on to house the Lieutenant-Governor of Portsmouth for the next fifty years).[5] The Commander-in-Chief moved in turn into the former Dockyard Commissioner's house, which still stands within HMNB Portsmouth.[4]

During the Second World War the Command Headquarters was at Fort Southwick.[6] Operation Aerial, the evacuation from western French ports in 1940, was commanded by Admiral William Milbourne James, the Commander-in-Chief. James lacked the vessels necessary for convoys and organised a flow of troopships, storeships and motor vehicle vessels from Southampton, coasters to ply from Poole and the Dutch schuyts to work from Weymouth, while such warships as were available patrolled the shipping routes. Demolition parties sailed in the ships but it was hoped that supplies and equipment could be embarked as well as troops.[7]

In 1952 the Commander-in-Chief took up the NATO post of Commander-in-Chief, Channel (CINCHAN). This move added Allied Command Channel to the NATO Military Command Structure. The admiral commanding at Portsmouth had control naval operations in the area since 1949 under WUDO auspices.[8]

The post of Commander-in-Chief, Portsmouth was merged with that of Commander-in-Chief, Plymouth in 1969 to form the post of Commander-in-Chief, Naval Home Command.[9] The posts of Second Sea Lord and Commander-in-Chief Naval Home Command were amalgamated in 1994 following the rationalisation of the British Armed Forces following the end of the Cold War.[10] In 2012, however, all distinct Commander-in-Chief appointments were discontinued, with full operational command being vested instead in the First Sea Lord; he now flies his flag from HMS Victory.[11]
