Fort Brockhurst is one of thePalmerston Forts, inGosport, England, and ascheduled monument.[1] It is now anEnglish Heritage property.
Fort Brockhurst was designed byWilliam Crossman[2] in the 19th century to protectPortsmouth. Built between 1858 and 1862, it was one of a chain of five similar forts known as the Gosport Advanced Line. The other forts areFort Elson to the north andFort Grange,Fort Rowner andFort Gomer to the south. With their formidable firepower, their main purpose was to guard the dockyards from potential attack from landing areas on theHampshire coast. Construction took place amidfears of a French invasion at the time, which, in the event, never occurred.
Changes in artillery technology meant that the fort was obsolete before construction was even completed. Increases in range left the fort too close to the dockyard, meaning that a landing force that had arrived elsewhere on the coast would not need to pass the fort in order to bombard Portsmouth harbour.[3] This was the reason for the construction ofFort Fareham at a greater distance from the harbour, which was completed six years later in 1868.
From 18 September 1882 onwards,[a] it was used as a depot, to demobilise soldiers returning from India, whose time period ofactive service had come to an end. In 1898, on average from 9,000 to 10,000 soldiers were passing through on an annual basis. During the 1880s, it used to take fully a week to get a big detachment through the depot, but in subsequent years the soldier was only spending several days at the depot, prior to their transfer to theArmy Reserve, and civilian life.[b] When all necessary formalities had been completed, the ex-soldier was marched toFort Brockhurst railway station, to take the train to their home.[6]
In August 1914, 9th (Heavy) BatteryRoyal Garrison Artillery was formed at the fort as part of the raising ofKitchener's Army.[7] It suffered minor bomb damage during the Second World War, but never saw action under its intended purpose. The fort did remain in commission however until 1957, serving variously as accommodation, storage and training facilities.[3]
Although modern life has encroached on the fort, its fabric remains largely unaltered and the parade ground, gun ramps and moated keep can all be viewed.Constructional details of thecasemates are able to be seen due to unrepaired Second World War bomb damage at the north-east corner.It is currently used as a store for English Heritage's reserve collections. The fort is occasionally open to the public, while the grounds are freely accessible.[8]
The polygonal shape of the fort was a revolutionary change from the prevailing orthodoxy of forts designed with angle bastions for defence. The new forts could be more easily adapted to the terrain and allowed a greatly increased number of heavy guns mounted on the ramparts to prioritise offence over defence. Each fort was located within gunshot of the next to allow overlapping fields of fire and mutual support.
The fort was surrounded by a moat and the entrance on the southeast side was approached by adrawbridge much like a medieval castle. This led to a circular keep, also moated, which served as a place for local defence, being equipped with twenty light guns. The nineteen heavy guns of the main armament were mounted on the ramparts reached by two ramps on the enclosed parade ground in the middle of the fort. A lower tier of eight guns, four in casements, on each flank provided cross fire support with Elson and Rowner. Beyond the moat on the north side was a triangularredan accessed by a covered way to allow riflemen to cover attempts to bridge the moat. Similarly there werecaponiers at the angles of the ramparts to allow riflemen to cover the moat.[9][page needed]
Fort Rowner to the southwest is in a similar state of preservation, but the military base RAF Gosport, now known asHMS Sultan, was built around it in 1914, and it is opened to the public only once a year under the banner of "Heritage Open Week."
