Essex at War From Old Photographs 

Essex is populated with defensive structures that have gone some way to combating the threat of invasion. From the remains of ancient castles through to Napoleonic Martello towers, nineteenth-century forts and Second World War defences, the perilous history of Essex can be seen in all corners of the county. Remains of what were once large military barracks can now mainly only be found hidden among more modern constructions. Many of the military structures of Essex are mentioned and illustrated in Essex at War. From ancient prints of thriving military settlements to the modern photographs of unused and often derelict buildings, this book will appeal to anyone interested in the history of the county.
