14th Cavalry Brigade (British Indian Army)

The Nottinghamshire and Derbyshire Mounted Brigade (later numbered as the 7th Mounted Brigade) was a yeomanry brigade of the British Army, formed as part of the Territorial Force in 1908.

It served dismounted in the Gallipoli Campaign before being remounted to serve in the Salonika and Sinai and Palestine Campaigns in World War I.

In April 1918, it was merged with elements of the 9th (Secunderabad) Cavalry Brigade to form 14th Cavalry Brigade. It remained in Palestine after the end of the war on occupation duties.

Formation
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.

As the name suggests, the units were drawn from Nottinghamshire and Derbyshire.

Nottinghamshire and Derbyshire Mounted Brigade
The brigade was embodied on 4 August 1914 upon the outbreak of World War I. Initially, it concentrated in Berkshire and on 5 August 1914 joined the 1st Mounted Division. On 2 September it was transferred to the 2nd Mounted Division and in mid November 1914 it moved with its division to Norfolk on coastal defence duties.

Egypt
In April 1915, the 2nd Mounted Division moved to Egypt arriving at Alexandria between 19 and 21 April and was posted to Cairo by the middle of May. In May 1915, the brigade was designated 3rd (Nottinghamshire and Derbyshire) Mounted Brigade.

It was dismounted in August 1915 and took part in the Gallipoli Campaign. Each regiment left a squadron headquarters and two troops (about 100 officers and men) in Egypt to look after the horses.

Gallipoli
The brigade landed at Suvla Bay on the night of 17/18 August and moved into reserve positions at Lala Baba on the night of 20 August. On 21 August it advanced to Chocolate Hill under heavy fire and took part on the right flank of the attack on Hill 112.

Due to losses during the Battle of Scimitar Hill and wastage during August 1915, the 2nd Mounted Division had to be reorganised. On 4 September 1915, the 2nd Composite Mounted Brigade was formed from the 3rd (Notts and Derby) and 4th (London) Mounted Brigades. The brigade formed a battalion sized unit 3rd Nottinghamshire and Derbyshire Regiment. The brigade embarked for Mudros on 2 November and returned to Egypt in December 1915 where it was reformed and remounted.

7th Mounted Brigade
The brigade left the 2nd Mounted Division on 18 and 19 January 1916. In February 1916 the brigade was sent to take part in the Salonika Campaign. On 31 March 1916, the remaining Mounted Brigades were numbered in a single sequence. As a consequence, the Nottinghamshire and Derbyshire Mounted Brigade was redesignated as 7th Mounted Brigade.

The brigade arrived back in Egypt from Salonika in June 1917, less the Derbyshire Yeomanry which remained in Macedonia as GHQ Troops with the British Salonika Army. The brigade served variously as Corps Troops with the Desert Mounted Corps and XXI Corps and on attachment to the Yeomanry Mounted Division.

14th Cavalry Brigade
In March 1918, the 2nd Indian Cavalry Division was broken up in France. The Canadian (Canadian Cavalry Brigade) and British units (notably 7th Dragoon Guards, 8th Hussars and N and X Batteries RHA) remained in France and the Indian elements were sent to Egypt.

By an Egyptian Expeditionary Force GHQ Order of 12 April 1918, the mounted troops of the EEF were reorganised when the Indian Army units arrived in theatre. On 24 April 1918, the 2nd Mounted Division was formed on the Indian Establishment and the 7th Mounted Brigade was assigned to it.

On 24 April 1918, the 7th Mounted Brigade was merged with elements of the 9th (Secunderabad) Cavalry Brigade: On 22 July 1918, the 1st Mounted Division was renumbered as the 5th Cavalry Division and the brigade as 14th Cavalry Brigade. The sub units (Signal Troop, Combined Cavalry Field Ambulance and Mobile Veterinary Section) were renumbered on the same date.
