1st Mounted Division (later 1st Cyclist Division)

History of the 1st Mounted Division

The Mounted Division was assembled for home defence in August 1914, bringing together four existing Mounted Brigades. It formed a headquarters in Bury St Edmunds, but the units were as far away as Ipswich and North Walsham. Later in August the Division was ordered to move to Churn. On creation there of a 2nd Mounted Division this one was named as the 1st Mounted Division. The original mounted brigades were now transferred to the 2nd Mounted Division and their places taken by their “second line”.The last two “first line” brigades left in March 1916.

During July 1916 the units of Yeomanry were formally dismounted and reorganised as Cyclist Regiments. Late in the month the name of the Division was changed to the 1st Cyclist Division.

The Division was broken up in November 1916.

The former 2/2nd Mounted Division was then renamed as a new 1st Mounted Division.
