The regiment was deployed near Ghyvelde, with the batteries either side of a canal, linked by a footbridge; 235 Bty was personally deployed by Maj-Gen Alexander. The batteries fired off a lot of spare ammunition, though OPs were difficult to find in the flat country. 236 Battery came under fire, but shifted to the flank, while Germans continued to shell their old position. Early on 31 May the regiment was ordered to thin out, leaving just the gun detachments and signallers while the remainder went into Dunkirk to join the evacuation (Operation Dynamo) that was under way. 235 Battery came out of action when its gun positions were inundated by seawater entering the breached dykes; 236 Bty remained in action until 10.00 on 1 June. Then the guns were spiked, the sights removed, and the Scammells driven into the canals, while the exhausted gun detachments made their way to Malo-les-Bains. They waded out to the small boats and were transferred to a Royal Navy minesweeper. The CO, Lt-Col Servaes, had become separated on the road, and was one of the last to leave.
