The Eastern Mounted Brigade was a formation of the Territorial Force of the British Army, organised in 1908.

[2] Three other yeomanry regiments (Hertfordshire, Bedfordshire and Northamptonshire) were attached for training in peacetime.

[4] The brigade, commanded by Henry West Hodgson, was mobilised on 4 August 1914 at the outbreak of the First World War, concentrated in the Ipswich area of Suffolk and joined the 1st Mounted Division on formation.

[10] In this period, the brigade consisted of the three yeomanry regiments, a signal troop and the field ambulance under the command of Br.-Gen. H. W.
