# 5th Cavalry Brigade (United Kingdom)

The 5th Cavalry Brigade was a cavalry brigade of the British Army. It served in the Napoleonic Wars (notably at the Battle of Waterloo), in the First World War on the Western Front where it was initially independent before being assigned to the 2nd Cavalry Division, and with the 1st Cavalry Division during the Second World War.

## History
### Napoleonic Wars

From June 1809, Wellington organized his cavalry into one, later two, cavalry divisions (1st and 2nd) for the Peninsular War. These performed a purely administrative, rather than tactical, role; the normal tactical headquarters were provided by brigades commanding two, later usually three, regiments. The cavalry brigades were named for the commanding officer, rather than numbered. For the Hundred Days Campaign, he numbered his British cavalry brigades in a single sequence, 1st to 7th. The 5th Cavalry Brigade consisted of:
* 7th (The Queen's Own) Regiment of (Light) Dragoons (Hussars)
* 15th (The King's) Regiment of (Light) Dragoons (Hussars)
* 2nd Hussars, King's German Legion
It was commanded by Sir John Colquhoun Grant (British cavalry general). The 13th Regiment of Light Dragoons was attached to the brigade (from 7th Cavalry Brigade) in the absence of the 2nd Hussars, KGL.
The brigade took part in the Battle of Waterloo. During the battle, the 7th Hussars suffered 155 casualties (56 killed, 99 wounded), the 15th Hussars 79 (23 killed, 51 wounded, 5 missing) and the 13th Light Dragoons 108 (12 killed, 78 wounded, 18 missing). This represented a loss rate of about 27%.

### First World War
#### Mobilization

5th Cavalry Brigade was a peacetime formation of the British Army, based in Northern and Eastern Commands. At the outbreak of the war, it was headquartered at York and commanded the 2nd Dragoons (York), 12th Lancers (Norwich), 20th Hussars (Colchester) and 5th Signal Troop, Royal Engineers (York). Ipswich-based V Brigade, RHA (G and O Batteries) was attached. On mobilization, the brigade took on a role independent of The Cavalry Division. It moved to France in August 1914 with its three cavalry regiments and signal troop, and with the addition of J Battery, RHA, 4th Field Troop, Royal Engineers, and 5th Cavalry Brigade Field Ambulance.

#### Early Actions

In its independent role, the brigade took part in the Battle of Mons (23–24 August), Cerizy (28 August), the Retreat from Mons (23 August–5 September) and in the Battle of the Marne (6–9 September). On 6 September, it joined 3rd Cavalry Brigade in Gough's Command (under 3rd Cavalry Brigade's Br-Gen Hubert Gough). As part of Gough's Command, it took part in the First Battle of the Aisne (12–15 September). On 13 September, Gough's Command was redesignated as 2nd Cavalry Division with the addition of divisional troops (RHA, RE, etc.). It remained with 2nd Cavalry Division on the Western Front until the end of the war.

#### 2nd Cavalry Division

In 1914, the brigade, with the division, took part in First Battle of Ypres, notably the battle of Gheluvelt (29–31 October). In 1915, the division was in action at the Battle of Neuve Chapelle (10–12 March 1915) and the Second Battle of Ypres notable the Battle of St Julien (26 April–3 May) and the Battle of Bellewaarde Ridge (24–25 May).
On 26 February 1916, a Machine Gun Squadron was formed from the machine gun sections of the brigade's constituent regiments.
1916 saw no notable actions, but in 1917 the division saw action in the Battle of Arras (First Battle of the Scarpe, 9–11 April). and the Battle of Cambrai (the Tank Attack of 20–21 November, the Capture of Bourlon Wood of 24–28 November and the German Counter-Attack of 30 November–3 December). At other times, the brigade formed a dismounted unit and served in the trenches as a regiment under the command of the brigadier.

#### War of movement

1918 saw the return of the war of movement and the division took part in the First Battle of the Somme notably the Battle of St Quentin (21–23 March), the Battle of the Lys (Battle of Hazebrouck of 14–15 April), the Battle of Amiens (8–11 August) and the Second Battle of the Somme (Battle of Albert of 21–23 August and the Second Battle of Bapaume of 31 August–3 September).
The division was then split up with the 5th Cavalry Brigade serving with Fourth Army. It took part in the battles of the Hindenburg Line: the battles of St. Quentin Canal (29 September–2 October), Beaurevoir Line (3–5 October) and Cambrai (8–9 October); and in the Pursuit to the Selle (9–12 October). Its final action was to take part in the Advance in Picardy (17 October–11 November) including the Battle of the Sambre (4 November).

#### Armistice

At the Armistice, the brigade had reached Clairfayts with Fourth Army. On 15 November, the division was re-assembled near Maubeuge and ordered to advance into Germany as an advance screen for Fourth Army and form part of the Occupation Force. The move began on 17 November, Ciney and Rochefort were reached five days later and the 5th Cavalry Brigade crossed the German border south of St. Vith on 1 December.
In late December, the division moved to winter quarters south and south-east of Liège. It remained here until 30 January 1919 when it exchanged regiments with 1st and 3rd Cavalry Divisions then gradually moved back to England. The division ceased to exist at midnight 31 March / 1 April 1919.
