 | | Crookhorn Redoubt had subsidence problems, and was demolished in the 1870s - today there is absolutely no trace left of this fortification, and even its former boundaries are unclear. |
 | | Farlington Redoubt was to have been fitted with barracks and a magazine, together with substantial underground works to protect the ditches and to permit counter-mining (the process by which you defeat an enemies attempt to dig under your fortifications by tunnelling, or mining, towards their tunnels). |
 | | It was believed that Farlington Redoubt was linked to Fort Purbrook by a tunnel, but no evidence has been found for this at the Purbrook end, where logically it should appear at the end of the Musketry Gallery at the eastern angle, nor is such a tunnel shown on any plan. |
