The 2nd Cavalry Brigade was a brigade of the British Army. It served in the Napoleonic Wars (2nd Union Cavalry Brigade), the Boer War and in the First World War when it was assigned to the 1st Cavalry Division. Prior to World War I the brigade was based at Tidworth Camp in England; and originally consisted of three cavalry regiments and a Royal Engineers signal troop. After the declaration of war in August 1914, the brigade was deployed to the Western Front in France, where an artillery battery joined the brigade the following September and a Machine Gun Squadron in February 1916.
