Nelsons victory over Napoleon at the Battle of Trafalgar in 1805 ended any risk that Britain could be invaded. By 1859 advances in warfare and artillery meant that a British Government report found that the Martello Towers and Redoubts were not an important element of security against attack. The Redoubt slowly fell into disuse
Today the Redoubt provides the perfect setting for the rich military collections of The Royal Sussex Regiment, The Queen's Royal Irish Hussars and the Sussex Combined Services.
