Bridging generally comes under the purview of the Royal Engineers. The Royal Engineer Establishment was set up at Chatham in 1812; today, the Royal School of Military Engineering. There is some history at their site which is probably a good place to start: http://www.atra.mod.uk/Atra/RSME/rsmehistory.htm The Royal Engineers Museum of Military Engineering may be able to tell you about any publications of interest: http://www.army.mod.uk/royalengineers/heritage/museum/ Regards, Donnacha ----- Original Message ----- From: "E.A.Roberts" <[email protected]> To: <[email protected]> Sent: Sunday, July 13, 2003 10:57 PM Subject: 1800-1820s Army ordinance books > Does anyone know of the existence of any 1800-1820s British Army ordinance > books.
