Q (Sanna's Post)/HQ Battery was originally formed on the 1st of March in 1824,[1] in Poona India as 3rd Troop, The Bombay Horse Artillery. Between 1838 and 1857 the Troop saw action in the first Anglo-Afghan War, the First Anglo-Sikh War, the Second Anglo-Sikh War,, and the Anglo-Persian War. In 1858 the Battery saw service during the Indian mutiny. In 1862 the Battery was renamed C Battery, 4 Horse Brigade Royal Artillery and in 1864 became a Royal Horse Artillery Battery as C Battery, F Brigade RHA. Between 1864 and 1889 the Battery's title changed a further 5 times. In 1889 the Battery assumed the title of Q Battery Royal Artillery.
The Battery next saw service in the Boer war between 1899 and 1901. On 31 March 1900 the Battery had its finest hour when it saved its guns and the majority of General Broadwater's force from a vicious Boer ambush at Koorn Spruit, near Sanna's Post. As the Battery galloped away to the rear in line, the Boers, seeing that part of their prey was escaping, opened fire with rifles from the edge of the Spruit. Q Battery's guns were severed for four hours in that exposed position, subjected all the time to continuous rifle fire at 1,000 yards range - it must be remembered that at the time the guns had no shields![citation needed] The Battery fought with such collective gallantry and skill that Field Marshal Lord Roberts VC, directed that 4 Victoria Crosses should be awarded to the Battery,one to an officer, one to an NCO, one to a Gunner & one to a Driver. It is the most highly decorated action in the history of the Royal Regiment of Artillery. In addition 3 Distinguished Conduct Medals were also awarded. In 1926 the Battery was granted the honour title "Sanna's Post".
During the First World War the Battery saw continuous action on the western front. At the end of the Great War the Battery's name changed again twice before being renamed Q Battery Royal Field Artillery in 1924.
