The 102nd (Pembroke and Cardiganshire) Field Regiment, Royal Artillery, was a Welsh unit of Britain's part-time Territorial Army (TA) formed after World War I from an existing Yeomanry Cavalry regiment. It fought in the Tunisian campaign and was then converted to medium artillery, in which role it fought through the Italian campaign, including the Battles of Monte Cassino, the Gothic Line, and the final Spring 1945 offensive. The regiment continued in the postwar TA, and a successor unit continues in today's Army Reserve. Origin The Pembroke Yeomanry was a cavalry unit of Britain's part-time Territorial Force (TF), which had served in World War I. After the TF was reconstituted on 7 February 1920 only the 14 most senior Yeomanry regiments remained horsed, the others being re-roled, generally in the Royal Field Artillery (RFA). The Pembroke Yeomanry (ranked 17th) was converted on 3 September 1920 into 102nd (Pembroke and Cardigan) Brigade, RFA with the following organisation: Brigade HQ at Greenhill Avenue, Tenby 405 (Pembroke) Battery at Bush Camp, Pembroke Dock 406 (Pembroke) Battery (Howitzer) at Haverfordwest 407 (Cardigan) Battery at Cardigan 408 (Cardigan) Battery at Aberystwyth In 1924 the RFA was subsumed into the Royal Artillery (RA), and the word 'Field' was inserted into the titles of its brigades and batteries. The 102nd was defined as an 'Army Field Brigade' serving as 'Army Troops' in 53rd (Welsh) Divisional Area and The brigade was defined as 'Army Troops' in 53rd (Welsh) Divisional Area and 53rd (Welsh) Divisional Signals also included 231st Field Artillery Signal Section, Royal Corps of Signals, to service the brigade. The establishment of a TA artillery brigade was four 6-gun batteries, three equipped with 18-pounder guns and one with 4.5-inch howitzers, all of World War I patterns. However, the batteries only held four guns in peacetime. The guns and their first-line ammunition wagons were still horsedrawn and the battery staffs were mounted. Partial mechanisation was carried out from 1927, but the guns retained iron-tyred wheels until pneumatic tyres began to be introduced just before World War II. By 1930 the HQ of 102nd (Pembroke & Cardigan) Army Brigade had moved to Carmarthen Barracks, and by December 1934 it was at Haverfordwest. In 1931 the Pembroke batteries changed their subtitles to 'Pembroke Yeomanry' and in 1937 'Cardigan' in the brigade and battery titles was altered to 'Cardiganshire'. In 1938 the RA modernised its nomenclature and a lieutenant-colonel's command was designated
