XIV Brigade , Royal Horse Artillery XIV Brigade , Royal Horse Artillery was a brigade of the Royal Horse Artillery which existed in the early part of the 20th Century . It had been dissolved before World War I but was reformed for the war . It served with 7th Division on the Western Front before becoming XIV Army Brigade , RHA in February 1917 . It was disbanded at the end of the war . Formation . Royal Horse Artillery brigades did not exist as an organizational or operational grouping of batteries until 1 July 1859 when the Horse Brigade , Royal Artillery was formed . The brigade system was extend to five ( later six ) brigades when the horse artillery of the Honourable East India Company had been transferred to the British Army in 1861 . These brigades were reduced to five in 1871 , then to three ( of 10 batteries each ) in 1877 and to two ( of 13 batteries each ) in 1882 . The brigade system was finally abolished in 1889 . As battery designations were tied to the brigade that the battery was assigned to , batteries were redesignated in a bewildering sequence as they were transferred between brigades . For example , E Battery of C Brigade ( E / C Bty ) might become N Battery of A Brigade ( N / A Bty ) upon transfer . Henceforth , batteries were designated in a single alphabetical sequence in order of seniority from date of formation . The brigade system was revived in 1901 . Each brigade now commanded just two batteries and a small staff ( a Lieutenant - Colonel in command , an adjutant and a brigade sergeant major ) . Initially , batteries were not assigned to brigades in any particular order , but in 1906 , at the insistence of Edward VII , brigades were redesignated so that batteries were roughly in order of seniority ( hence I Brigade commanded A Battery and B Battery ) . XIV Brigade , RHA was formed on 1 March 1901 as the IV Brigade - Division , RHA with Z Battery and AA Battery . In 1903 it was redesignated as IV Brigade , RHA and was stationed at Woolwich . On 1 October 1906 , it was redesignated as XIV Brigade , RHA and was dissolved on 1 August 1913 . AA Battery had been disbanded on 1 May 1913 and Z battery was transferred to II Brigade , RHA at Canterbury . World War I . Reformed . XIV Brigade , RHA was reformed in September 1914 with C Battery ( from II Brigade , RHA ) , F Battery ( from IV Brigade , RHA ) and XIV RHA Brigade Ammunition Column . It joined 7th Division at Lyndhurst on formation . With 7th Division , it crossed to Belgium on 4 and 5 October 1914 ( landing at Zeebrugge on 6 October ) and served with the division on the Western Front until February 1917 . While with the division , it saw considerable action serving at the Siege of Antwerp , the First Battle of Ypres , and in the battles of Neuve Chapelle , Aubers Ridge , Festubert , Loos , and of the Somme . Changes in organization . On 19 October 1914 , C Battery left the brigade to join XV ( later IV ) Brigade , RHA in 3rd Cavalry Division . It was not replaced until 21 December 1914 when T Battery joined from The Force in Egypt . On 19 June 1915 , F and T batteries replaced their 13 pounder s with six 18 pounder s each . 57th ( H ) Battery , RFA joined from XXXVII ( Howitzer ) Brigade , RFA on 27 November 1914 . It returned to XXXVII ( H ) Brigade on 2 March 1915 . D ( H ) / XIV Battery was formed on 17 May 1916 with one section of 31st ( H ) Battery and one section of 35th ( H ) Battery ( both of XXXVII ( H ) Brigade , RFA ) . On 7 October 1916 , 509th ( H ) Battery ( four 4 . 5 " howitzers ) joined the brigade . On 13 February 1917 it was broken up to make up 31st ( H ) and 35th ( H ) batteries to six howitzers each .
