Throughout the operations of this day the trench mortar batteries did most valuable work, Captain Buckley, the D.T.M.O., and Captain Traill, commanding Y/20 Battery, both receiving the M.C.

In the course of the fighting some of the Canadian communications broke down. Fortunately, with the help of recently completed buried cables, some laid in the sewers of Ypres, the 20th Divisional Signal Company was able to maintain communication for the Canadians for a considerable time during the most critical period of the fighting.

During the night the damage done to the trenches was repaired and a new line dug. Patrols searched the front, bringing in prisoners, and discovering parties of the enemy consolidating their line. These parties were brought under fire from our machine guns and snipers, and suffered much loss. Touch with the Canadians, which had been lost during the day’s fighting, was re-established, and was maintained throughout the night.

The casualties of the 60th Brigade were about 100, of which 77, including 25 killed, were in the 12th R.B.

On the 10th of June the following message was received from G.O.C. 3rd Canadian Division: “I am writing on behalf of the whole of the 3rd Canadian Division to thank you most heartily for the immediate and substantial assistance which the 20th Division gave us on June 2nd and on the subsequent days, and to ask you also to repent our thanks to General Butler and to the 12th K.R.R.C., who sent two companies to strengthen our line. We shall always remember with gratitude the help given so promptly and freely by your Division.”

The next few days were spent in harassing the enemy parties working on their new positions, and in work on our own trenches. On the 8th and 9th the 6Oth Brigade was relieved by the 61st in the right sub-sector. Though the 60th went into reserve, the troops had not much rest, for by the 10th, 600 men of the Brigade were working nightly on the new line from Cork Cottages to Dragoon Farm, and 200 men were employed in burying cables. On the 11th an additional 600 men (300 from the artillery and 300 from the reserve brigade) were required to bury cables for the XIVth Corps.

The last phase of these operations was carried out on the 13th, when the Canadians attacked in order to regain the lost ground. To assist them, the 20th Division was ordered to discharge gas and smoke along its front and then push out patrols, following these up by larger raiding parties if possible, at four selected points in the German line. Zero was 1.30 A.M. on the 13th. Owing to the short notice that had been given, it was found impossible to get all the gas cylinders into the trenches in time. By some mistake in one part of the line, the smoke bombs were thrown three minutes before zero. This unfortunately gave alarm to the enemy, who thus had time to put on gas masks.

The gas, discharged at zero from 130 cylinders, went well and quickly. In three minutes practically all the rifle and machine-gun fire from the German trenches had ceased. The artillery barrage also began at zero, and was most effective. After twenty-five minutes it lifted to allow our infantry raiding parties to go forward.

On the right one party of the Somerset L.I., under Captain J. N. C. Peard, was held up by the wire near Railway Wood. Owing to the gas this party had to put on gas masks, and while attempting to cut a passage through the wire 3 men were killed and Captain Peard and 10 men wounded. All the wounded, however, were brought back safely. A party of the 11th K.R.R.C. under Lieut. H. A. Denison got in at the Mound (south-west of Verlorenhoek), which was found to be practically obliterated by our trench mortar bombardment. This party beat off a counter attack, and returned with only five slight casualties. The left party got as far as the German wire and reconnoitered the position, but, being only a small patrol, did not attempt to enter the trenches.

The 1st Canadian Division in a most successful attack regained Mount Sorrel and Observatory Ridge.
