Southsea Castle, historically also known as Chaderton Castle, South Castle and Portsea Castle, is an artillery fort originally constructed by Henry VIII on Portsea Island, Hampshire, in 1544. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the Solent and the eastern approach to Portsmouth. The castle had a square central keep, two rectangular gun platforms to the east and west, and two angled bastions to the front and rear, and was an early English example of the trace italienne-style of fortification popular on the Continent. The Cowdray engraving of the Battle of the Solent in 1545 depicted Henry VIII visiting the castle. Despite several serious fires, it remained in service and saw brief action at the start of the English Civil War in 1642 when it was stormed by Parliamentary forces.
The Royal Commission on the Defence of the United Kingdom was a committee formed in 1859 to enquire into the ability of the United Kingdom to defend itself against an attempted invasion by a foreign power, and to advise the British Government on the remedial action required. The appointment of the Commission had been prompted by public concern about the growing military and naval power of the French Empire and was instigated by the Prime Minister, Henry Temple, 3rd Viscount Palmerston, who came to be closely associated with the project. In the following year, the Commission's report recommended a huge programme of fortification to defend the country's arsenals and naval bases. Many of the recommendations were acted upon; however, the great expense, the length of time taken to complete the various works and their perceived usefulness were all subjects of critical political, press and public debate.
Fort Gilkicker is a historic Palmerston fort built at the eastern end of Stokes Bay, Gosport, Hampshire England to dominate the key anchorage of Spithead. It was erected between 1863 and 1871 as a semi-circular arc with 22 casemates, to be armed with five twelve-inch guns, seventeen ten-inch guns and five nine-inch guns. The actual installed armament rather differed from this. In 1902 the RML guns were replaced by two 9.2-inch and two six-inch BL guns, and before the First World War the walls were further strengthened with substantial earthwork embankments. The fort was disarmed in 1956 and used for storage until 1999, and is currently in a state of disrepair.
