Next morning the full German attack began as they established small bridgeheads near Calonne. Lieutenant-Colonel Simpson gathered stragglers from the Royal Warwicks and sent them to join a company of 2nd Dorsetshire Regiment, the support battalion positioned next to his D Troop. The regiment received urgent messages from the infantry that all possible fire was needed to suppress the German mortars and machine guns. Despite the church tower coming under fire the OP successfully picked out specific targets: one machine gun position was destroyed by just four rounds, while an enemy OP in a chimney was engaged with Shrapnel shell by D Troop. The bridges between Calonne and Antoing were targeted, and enemy infantry concentrating for an attack were dispersed by shellfire. One infantry unit sent back a message to the gunners, 'Thank God for you', and the Commanding Officer (CO) was congratulated on the regiment's shooting by the CO of the 1st Royal Scots. However, by the end of the day the ammunition position was very bad, many vehicles had been put out of action by enemy fire, and F Troop had lost all its guns. The regiment was ordered to withdraw in the dark to previously chosen positions in the rear.
