The 1st South Western Mounted Brigade was a formation of the Territorial Force of the British Army, organised in 1908. By 1915 its regiments had been posted away so it was broken up; it never saw active service as a brigade. The Headquarters may have formed the HQ for 2/1st Southern Mounted Brigade.

Under the terms of the Territorial and Reserve Forces Act 1907 (7 Edw.7, c.9), the brigade was formed in 1908 as part of the Territorial Force. It consisted of three yeomanry regiments, a horse artillery battery and ammunition column, a transport and supply column and a field ambulance.[1] The Queen's Own Dorset Yeomanry was attached for training in peacetime.[2]

As the name suggests, the units were drawn from South West England, predominantly Wiltshire, Somerset, Hampshire and Dorset.[3]

World War I[edit]

The brigade was mobilised on 4 August 1914 at the outbreak of the First World War. Initially assigned to the Portsmouth Defences in August 1914,[4] the brigade moved to the Forest Row area of Sussex in October 1914.[2] Thereafter, the regiments left the brigade for other formations.

Regimental HQ and D Squadron joined 38th (Welsh) Division at Winchester
A Squadron joined 40th Division at Aldershot
B Squadron joined 41st Division at Aldershot about November 1915.
It was later brought back together as a corps cavalry regiment. It was converted to infantry and absorbed into 6th (Wiltshire Yeomanry) Battalion, Wiltshire Regiment in September 1917.[10]
Regimental HQ and B Squadron joined 60th (2/2nd London) Division at Warminster on 26 April 1916
A Squadron joined 58th (2/1st London) Division at Ipswich on 21 March 1916
C Squadron joined 61st (2nd South Midland) Division at Ludgershall on 18 March 1916.
It was later brought back together as a corps cavalry regiment. In September 1917 it was converted to infantry and absorbed into the 15th (Hampshire Yeomanry) Battalion, Hampshire Regiment.[12]

By 1915, with its regiments having been posted away, the brigade was dissolved. The headquarters staff may have been used to form the 2/1st Southern Mounted Brigade.[2][5]
