The King's and No. 4 Companies moved up Mory Switch supported by one tank, while another worked on the southern flank. The fog was still thick, and as the first tank advanced it was suddenly engaged at very close range by a stray machine-gun post. Armour-piercing bullets were used, and the engine and water jacket were penetrated. It was therefore necessary to find the other tank, which could be heard working in the fog, and after an unsuccessful attempt to get it going in the right direction, it eventually succeeded in moving forward at 8.30 A.M., supported by the King's Company and a platoon of No. 4 Company. But soon afterwards the fog lifted, and the tank was immediately put out of action. Germans in bodies of fifty and one hundred could be seen standing about in Bank's Trench, but as the King's Company and a platoon of No. 3 Company were close by, Lord Gort did not give the order to engage these hostile parties with machine-gun fire, until he could ascertain if they were prisoners surrendering or not. After a lapse of five minutes fire was opened on them, and they disappeared into their trenches. Meanwhile the enemy opened a very heavy and concentrated machine-gun fire on Mory Switch, and engaged the disabled tank with a field-gun. Lord Gort having been called back to Battalion Headquarters to speak to the Brigadier on the telephone with reference to the attack of the Sixty-second Division, which was timed to begin at 9 A.M., ordered Captain Wolrige-Gordon to hold on to Mory Switch and Camouflage Copse. But the enfilade machine-gun fire made this impossible, more especially as the right flank was quite unsupported, and the three companies had to withdraw from Mory Switch to the north-west of Mory. At 4 P.M. after a severe bombardment the Germans developed a counter-attack, which was met by the Sixty-second Division, and driven back. Battalions of this division returned to the attack, and regained some ground, while the 1st Battalion reoccupied Mory Switch. Lord Gort told the captain of the leading company of the battalion from the Sixty-second Division that he was prepared to push on to the sunken road, if his company would co-operate, but the Company Commander replied that the right flank of his battalion was entirely unsupported, and that therefore any further advance was out of the question. The Sixty-second Division was subsequently withdrawn to the line from which they started, but the 1st Battalion was able to maintain its position and to clear Hally Copse of the enemy. That night it withdrew to Boiry St. Martin, and was relieved by the 2nd Battalion Grenadier Guards.
