over to the new brigade. On 1 June 1924 the RGA was subsumed into the Royal Artillery (RA) and the titles were adjusted. The brigade was defined as 'Army Troops' in 53rd (Welsh) Divisional Area and 53rd (Welsh) Divisional Signals also included 212th Medium Artillery Signal Section, Royal Corps of Signals, to service the brigade. The establishment of a medium brigade was four 4-gun batteries, one equipped with 60-pounder guns and three with 6-inch howitzers, all of World War I patterns. These were finally fitted with pneumatic tyres in 1937. In 1938 the RA modernised its nomenclature and a lieutenant-colonel's command was designated a 'regiment' rather than a 'brigade'; this applied to TA brigades from 1 November 1938. The TA was doubled in size after the Munich Crisis, and most regiments formed duplicates. During 1939 61st (C&DY) Med Rgt divided as follows: 61st (Carnarvon & Denbighshire) Medium Regiment Regimental HQ at Colwyn Bay 242 (Carnarvon) Med Battery at Llandudno 243 (Denbigh) Med Battery at Colwyn Bay 69th Medium Regiment RHQ at Bangor 241 (Carnarvon) Med Battery at Bangor 244 (Denbigh) Med Battery at Wrexham Each battery would consist of two 4-gun Troops. World War II Mobilisation When the TA was mobilised on 1 September, just ahead of the outbreak of World War II on 3 September, the regiment mobilised at Colwyn Bay. Under the command of the recently promoted Lt-Col G.E. Fitzhugh (who had commanded 243 Bty before the war) it crossed to France to join the British Expeditionary Force (BEF). Although classed as 'Army Troops' it was attached to 2nd Infantry Division in I Corps. Battle of France The period of 'Phoney War' ended with the German invasion of the Low Countries on 10 May, and in response the BEF advanced into Belgium under Plan D. Soon 61st (C&DY) Med Rgt was deployed with 2nd Division on the River Dyle, with the regiment at Chateau d'Etoiles on the extreme right of the BEF's line. C Troop fired the regiment's first round of the campaign at 17.00 on 13 May in support of 4th Brigade. However, the Germans had broken through the French positions in the Ardennes and the BEF was in danger pof being outflanked on the right. On 15 May the regiment had reports of enemy tanks approaching the gun positions and was withdrawn to Terbloc. On 16 May it was in action all day from positions some
