# 11th Cavalry Brigade (British Indian Army)

The London Mounted Brigade (later numbered as the 8th 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 the First World War.
In April 1918, it was merged with elements of the 8th (Lucknow) Cavalry Brigade to form 11th 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 (provided by the Honourable Artillery Company), a transport and supply column and a field ambulance. The 2nd County of London Yeomanry was attached for training in peacetime.
As the name suggests, the units were drawn from London.

## First World War
### London Mounted Brigade

The brigade was mobilised on 4 August 1914 at the outbreak of the First World War and concentrated in Berkshire. It joined 2nd Mounted Division on 2 September and moved with the division to East Anglia in November 1914.

#### Egypt

In April 1915, the 2nd Mounted Division moved to Egypt arriving at Alexandria on 27 April (City of London Yeomanry did not arrive until 6 May) and was posted to the Suez Canal Defences (near Ismaïlia) by the middle of May. In May 1915, the brigade was designated 4th (London) 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 morning of 18 August and moved into reserve positions at Karakol Dagh. It moved to "C" Beach, Lala Baba on 20 August. On 21 August it advanced to Chocolate Hill under heavy fire and took part in 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 4th London Regiment. The brigade embarked for Mudros on 2 November and returned to Egypt in December 1915 where it was reformed and remounted.

### 8th Mounted Brigade

The brigade left the 2nd Mounted Division on 18 January 1916 and was sent to Abbassia. It served as part of the Suez Canal Defences. On 31 March 1916, the remaining Mounted Brigades were numbered in a single sequence. As a consequence, the London Mounted Brigade was redesignated as 8th Mounted Brigade.
From November 1916 to June 1917, the brigade took part in the Salonika Campaign, serving as GHQ Troops with the British Salonika Army.
The brigade arrived back in Egypt from Salonika on 8 June 1917. The Machine Gun Squadron was formed in Egypt on 14 June. The brigade moved forward and joined the newly formed Yeomanry Mounted Division on 21 July 1917 at el Fuqari. From 31 October it took part in the Third Battle of Gaza, including the Battle of Beersheba and the Capture of the Sheria Position. It took part in the Battle of Mughar Ridge on 13 and 14 November and the Battle of Nebi Samwil for 17 to 24 November. From 27 to 29 November, it withstood the Turkish counter-attacks during the Capture of Jerusalem.
