The Childers Reforms of 1881 reorganised the infantry regiments of the British Army. The reforms were done by Secretary of State for War Hugh Childers during 1881, and were a continuation of the earlier Cardwell Reforms.
The reorganisation was effected by General Order 41/1881, issued on 1 May 1881, amended by G.O. 70/1881 dated 1 July, which created a network of multi-battalion regiments. In England, Wales and Scotland, each regiment was to have two regular or "line" battalions and two militia battalions. In Ireland, there were to be two line and three militia battalions. This was done by renaming the numbered regiments of foot and county militia regiments. In addition, the various corps of county rifle volunteers were to be designated as volunteer battalions. Each of these regiments was associated by headquarters location and territorial name to its local "Regimental District". The reforms became effective on 1 July.
From 1881, regimental seniority numbers were officially abolished and battalions came to be known by their number within the regiment and the regimental district name. Unofficially, the regiments were still referred to by their numbers by their officers and men, as tradition, and several regiments, such as "The Buffs" (the Royal East Kent Regiment), the Cameron Highlanders, and the "Black Watch", lobbied to keep their distinct names as part of their battalion titles.
In practice, it was not always possible to apply the scheme strictly: the Cameron Highlanders initially had only one regular battalion, while several regiments had more or fewer militia regiments than specified by the initial scheme. In addition, the King's Royal Rifle Corps and the Rifle Brigade (Prince Consort's Own) had no local regimental districts, and their affiliated militia and volunteer battalions were selected not on a territorial basis, but due to their "rifle" traditions. This structure lasted until 1948, when every regiment of line infantry had its regular battalions decreased to one, with only the three original Guards Division regiments retaining two regular battalions.
Also in 1881, short service was increased to seven years with the colours, and five with the reserve, of the twelve-year enlistment period that the Cardwell Reforms had introduced.[1][2][3] He also introduced the ability for time-served soldiers to extend service in the reserve by four years, albeit classed as the second division, or Section D, of the First Class Army Reserve.[4][5][6]
