The East and West Riding Regiment was a regiment of the British Territorial Army from 1999 to 2006. In 2006, it was re-designated as the 4th Battalion The Yorkshire Regiment. History The regiment was formed in 1999 by the amalgamation of the 3rd Battalion The Prince of Wales's Own Regiment of Yorkshire (Yorkshire Volunteers); 3rd Battalion The Duke of Wellington's Regiment (Yorkshire Volunteers); and the King's Own Yorkshire Yeomanry (Light Infantry) due to the reforms implemented in consequence of the Strategic Defence Review. The regimental headquarters was at Pontefract and the regiment, part of 15 (North East) Brigade, comprised five Rifle Companies: Ypres Company (Duke of Wellington's Regiment), at Huddersfield and Keighley(from C and B Companies, 3rd Battalion, Duke of Wellington's Regiment) Fontenay Company (Duke of Wellington's Regiment), at Barnsley and Sheffield(from HQ and A Companies, 3rd Battalion, Duke of Wellington's Regiment) Quebec Company (Prince of Wales's Own Regiment of Yorkshire), at Hull and Beverley(from B Company, 3rd Battalion, Prince of Wales's Own Regiment of Yorkshire) Imphal Company (Prince of Wales's Own Regiment of Yorkshire), at Worsley Barracks, York and Leeds(from A Company, 3rd Battalion, Prince of Wales's Own Regiment of Yorkshire) Minden Company (Light Infantry), at Wakefield and Batley(from HQ and C Squadrons, King's Own Yorkshire Yeomanry) No new cap badge was created for this regiment: soldiers wore their former regimental cap badge or were badged according to the company they joined. The regimental crest was a combination of the Light Infantry and the Prince of Wales's Own Regiment of Yorkshire cap badges and crest from the Duke of Wellington's Regiment. During the summer of 2004 the regiment adopted a single Tactical Recognition Flash (TRF) of the White Rose of Yorkshire on a black background (this design was previously used by the 49th (West Riding) Infantry Division between the First and early in the Second World War). The official Army abbreviation for the regiment was "E and WRR". In November 2004, the regiment dispatched a composite company (Normandy Company) to Basra, Iraq as part of 4th Mechanized Brigade of the Multi-National Division (South East) for a 6-month tour-of-duty. Prior to re-designation Two months prior to being re-designated as the 4th Battalion of The Yorkshire Regiment, the two Yorkshire companies of the Tyne-Tees Regiment were integrated into the structure of the regiment, and some of the regiment's companies were converted into other units; furthermore, the regimental HQ moved to York.
