(TA), leaving the original Regiment comprising Headquarters, 391st and 392nd Field Batteries. Second World War 98th Field Regiment (Surrey & Sussex Yeomanry Queen Mary's) Battle of France The regiment mobilised at Worthing under Lt-Col G.A. Ledingham, MC, TD, who had been the commanding officer (CO) since 1937, and it joined I Corps of the British Expeditionary Force (BEF) in France by 27 September 1939. Its guns were World War I vintage 18-pounders, some handed over by 1st and 2nd Regiments Royal Horse Artillery who were receiving more modern guns, and 98th also took over vehicles from its sister regiment, 144th. On 10 May 1940, the Phoney War ended with the German invasion of the Low Countries, so the BEF followed the pre-arranged Plan D and advanced into Belgium to take up defences along the River Dyle. 98th (S&SY) Field Rgt was with I Corps on the Dyle Line by 15 May 1940. However, the Panzers of the Wehrmacht's Army Group A had broken through the Ardennes and threatened the BEF's flank, so on 16 May it began to withdraw to the River Escaut. The regiment was with I Corps on the Escaut Line by 21 May 1940. By now the enemy was in the BEF's rear. To hold the line of the Aire Canal north of Saint-Omer the BEF organised a scratch force of rear elements ('Polforce'), and on 22 May 392 Bty was hastily sent to join the defenders on the Canal Line. The battery only had seven 18-pounders, so each was sent to cover one of the bridges against the advancing 1st Panzer Division: Hazebrouck: 15 minutes after digging in, the gun stopped an enemy column, knocking out the lead vehicles. It was then attacked by 11 tanks, putting one (possibly two) out of action before the gun crew were all wounded and the ammunition limber blown up. The gun was withdrawn with its wounded detachment. Arques: Sappers were blowing up the bridge when the gun arrived. Advancing enemy troops were firing on and nearing the gun position when it was relieved by the 12th Royal Lancers and withdrawn. Renescure: The gun destroyed enemy-held houses across the bridge and remained in action until late afternoon. One enemy tank was destroyed but mortar fire on the gun position forced a withdrawal; as the gun was being limbered up the tractor was hit and the position overrun. Wardrecques: The gun
