North Midland) Division. In April 1916, the regiment began to split up, with the RHQ and A Squadron joining the 69th (2nd East Anglian) Division in Yorkshire. One Squadron was attached to the 67th (2nd Home Counties) Division in Kent in October 1916. During the following winter, the remaining squadron went to France, where it was absorbed into the Tank Corps around August 1917. Of the two squadrons remaining in the United Kingdom, one was absorbed into the 6th Reserve Cavalry Regiment at Tidworth in March 1917, the other was disbanded. 3/1st Northamptonshire Yeomanry The 3rd Line regiment was formed in 1915 and in the summer it was affiliated to the 3rd Reserve Cavalry Regiment at Canterbury. Early in 1917, it was absorbed in the 6th Reserve Cavalry Regiment at Tidworth. Between the wars On 7 February 1920, the regiment was reconstituted in the Territorial Army with HQ at the Old Militia Barracks in Clare St, Northampton. It was initially established with three Squadrons. Following the experience of the war, it was decided that only the fourteen most senior yeomanry regiments would be retained as horsed cavalry, with the rest being transferred to other roles. As a result, on 1 March 1922, the regiment was one of eight converted and reduced to 7th (Northamptonshire) Armoured Car Company, Tank Corps. In 1922, it was renumbered as 25th (Northamptonshire Yeomanry) Armoured Car Company, Tank Corps, in October 1923 as 25th (Northamptonshire Yeomanry) Armoured Car Company, Royal Tank Corps, and in April 1939 it was transferred to the Royal Armoured Corps. In November 1938, the formation of a Mechanised Cavalry Brigade (TA) was announced, to comprise three Cavalry Light Tank Regiments. The Northamptonshire Yeomanry was selected to form part of this Brigade and ordered to expand to full Regimental status. By early 1939, Regimental Headquarters and "A" Squadron were based at Northampton, with "B" Squadron at Daventry and "C" Squadron at Brackley. This expansion coincided with the decision to increase the Territorial Army by forming duplicates of existing TA units. By 1939, it had become clear that a new European war was likely to break out, and the doubling of the Territorial Army was authorised, with each unit forming a duplicate. As a result of this move, the Northamptonshire Yeomanry was divided in May 1939 to form two Cavalry Light Tank Regiments: 1st Northamptonshire Yeomanry (TA) - Regimental Headquarters and "A" Sqn at
