"The origins of The Post Office Rifles lay in the Fenian scare of 1867,
resulting in a call for Special Constable to protect key installations, including post offices.
The following year, when the emergency was over, many of these constables said that they wished
to continue in the service of the Queen, and asked if a
Post office Volunteer Corps could be raised.

"Formed in 1868 as a Volunteer Battalion of The Rifle brigade,
it eventually became the 8th (City of London) Battalion, The London Regiment (Post Office Rifles).
For three-and-a-half years, the two line battalions fought at the front in World War I.
They earned many awards for bravery, of which the most outstanding must be the Victoria Cross won by Sergeant Knight
in the mud of Paschendaele. Like its sister battalions of the London Rifle Brigade and the 6th CLR,
the Post Office Rifles lives on in the history of The Royal Green Jackets."
