The Post Office Rifles was a unit of the British Army, first formed in 1868 from volunteers as part of the Volunteer Force, which later became the Territorial Force (and later the Territorial Army). The unit evolved several times until 1921, after which the name was lost during one of many reorganisations. History Beginnings – 49th Middlesex Rifle Volunteers Corps (Post Office Rifles) When the Volunteer Force was formed in 1859/60 Viscount Bury raised the 21st Middlesex Rifles Volunteer Corps (Civil Service Rifles) drawing its recruits from civil servants based in London. There were sufficient recruits from the GPO staff to form a Post Office company, which was placed under Captain John Lowther du Plat Taylor's command.
