The Role of the The Royal Horse Artillery in Great Britain.

The Royal Horse Artillery (RHA) was formed in 1793 as a distinct arm of the Royal Regiment of Artillery to provide horse artillery support to the cavalry units of the British Army.

The RHA has acquitted itself with distinction in the great wars of two centuries, the Napoleonic Wars, the Indian Mutiny, the Crimean War, the Peninsular War, the Anglo-Zulu War, the Boer War, World War I and World War II.

In 1859, the term "battalion" was replaced by "brigade".  This in turn was replaced by "regiment" in 1939. The five Horse Artillery brigades consisted of two batteries each. Between 1899 and 1924, the Royal Artillery was divided, with the creation of the Royal Field Artillery which utilized horse for its medium-calibre guns.

Horses are still in service for ceremonial purposes but were phased out from operational deployment in the 1930s.
