The Childers Reforms of 1881 took Cardwell's reforms further, with the linked regular regiments becoming two-battalion regiments and the militia formally joining them. On 1 July the 64th and 98th Foot became the 1st and 2nd Battalions of the Prince of Wales's (North Staffordshire Regiment) (the 'North Staffs') and the King's Own (3rd Staffordshire) Rifle Militia became the 4th Battalion (the 2nd Staffordshire Militia became the 3rd Bn). Militia battalions now had a large cadre of permanent staff (about 30). Around a third of the recruits and many young officers went on to join the Regular Army. It was not uncommon for Militia officers to be attached to Regular forces for a particular service: Lt-Col Charles Bill served with the staff on the Burma Expedition of 1886; he became commanding officer (CO) of the battalion on 29 May 1893.
