Eastern Division, Royal Artillery

The Eastern Division, Royal Artillery, was an administrative grouping of garrison units of the Royal Artillery, Artillery Militia and Artillery Volunteers within the British Army's Eastern District from 1882 to 1902.

Organisation
Under General Order 72 of 4 April 1882 the Royal Artillery (RA) broke up its existing administrative brigades of garrison artillery (7th–11th Brigades, RA) and assigned the individual batteries to 11 new territorial divisions. These divisions were purely administrative and recruiting organisations, not field formations. Most were formed within the existing military districts into which the United Kingdom was divided, and for the first time associated the part-time Artillery Militia with the regulars. Shortly afterwards the Artillery Volunteers were also added to the territorial divisions. The Regular Army batteries were grouped into one brigade, usually of nine sequentially-numbered batteries and a depot battery. For these units the divisions represented recruiting districts – batteries could be serving anywhere in the British Empire and their only connection to brigade headquarters (HQ) was for the supply of drafts and recruits. The artillery militia units (sometimes referred to as regiments) already comprised a number of batteries, and were redesignated as brigades, losing their county titles in the process. The artillery volunteers, which had previously consisted of numerous independent Artillery Volunteer Corps (AVC) of various sizes, sometimes grouped into administrative brigades, had been consolidated into larger AVCs in 1881, which were now affiliated to the appropriate territorial division.

Eastern Division, RA, listed third in order of precedence, was organised within Eastern District with the following composition (regular batteries changed location frequently):
 * Headquarters (HQ) at Great Yarmouth
 * 1st Brigade
 * HQ at Colchester
 * 1st Bty at Landguard Fort – formerly 15th Bty, 11th Bde
 * 2nd Bty at Sheerness – formerly 14th Bty, 8th Bde

 * 3rd Brigade at Ipswich – formerly Suffolk Artillery Militia (5 btys)
 * 1st (Norfolk and Suffolk) Norfolk Artillery Volunteers at Great Yarmouth
 * 1st Essex Artillery Volunteers at Stratford
 * 1st Lincolnshire Artillery Volunteers at Grimsby

Reorganisation 1889–1902
On 1 July 1889 the garrison artillery was reorganised again into three large territorial divisions of garrison artillery and one of mountain artillery. The names of the territorial divisions seemed arbitrary, with the Scottish units being grouped in the South Division, for example, but this related to where the need for coastal artillery was greatest, rather than where the units recruited. The artillery militia units regained their county designations, as did those volunteer units that had adopted brigade titles. After 1889 all were intended to include '(Eastern Division, Royal Artillery)' after their title, but many of the volunteers did not use them. From 1 August 1891 garrison artillery batteries were termed companies (unless they were equipped with specific guns, such as mountain batteries or position batteries), and some were grouped into double companies at this time before reverting to their previous numbers in March 1894.

Disbandment
In 1899 the Royal Artillery was divided into two distinct branches, field and garrison. The field branch included the Royal Horse Artillery (RHA) and the newly named Royal Field Artillery (RFA). The garrison branch was named the Royal Garrison Artillery (RGA) and included coast defence, position, heavy, siege and mountain artillery. The division became Eastern Division, RGA. The RGA retained the divisions until they were scrapped on 1 January 1902, at which point the Regular RGA companies were numbered in a single sequence and the militia and volunteer units were designated '--- shire RGA (M)' or '(V)' as appropriate.
