Fort Brockhurst
Fort Brockhurst was designed by William Crossman[2] in the 19th century to protect Portsmouth. Built between 1858 and 1862, it was one of a chain of five similar forts known as the Gosport Advanced Line. The other forts are Fort Elson to the north and Fort Grange, Fort Rowner and Fort Gomer to the south. With their formidable firepower, their main purpose was to guard the dockyards from potential attack from landing areas on the Hampshire coast. Construction took place amid fears 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 of Fort Fareham at a greater distance from the harbour, which was completed six years later in 1868.
