The fourth raid was also undertaken by the 47th Battalion. A comparatively long distance separated the two trench lines, some 200 yards. On this account an early start was imperative. Scarcely any resistance was encountered. Six Germans were killed, and others were pursued but not caught. The artillery preparation, under Lieutenant-Colonel McNaughton, and the trench-mortar work were all that could be desired.
The 75th Battalion carried out the fifth raid. Three officers and thirty-one other ranks constituted the raiding party. They moved out just after midnight, formed up outside our wire, and were within twenty yards of the German trench while it was still being bombarded. Rushing in as soon as the barrage lifted, they divided up into two parties, which bombed right and left for fifty yards. Some resistance was encountered by the right party, but five of the enemy were killed, three captured, and the rest escaped over the parados under fire from the covering party. The left party also experienced resistance, but reached their objective in spite of opposition. Dug-outs were bombed and the enemy forced to escape over the parados. After a successful withdrawal the artillery was again turned on to the front line. Of the six prisoners taken four bolted on the way back and came to an untimely end. The 7th Belgian Field Artillery supporting the raid, rendered excellent service, which earned the warm commendation of all concerned in the operation.
The sixth raid, by the 54th Battalion was the most elaborate of all. Four officers and fifty-eight other ranks took part. The objective was No. 2 Crater at St. Eloi. Almost at the start the officers in charge were wounded. An unavoidable loss of direction and control naturally resulted, though the parties succeeded in reaching their objectives. An unfortunate contretemps arose from the fact that the bugler who was to have sounded the signal to retire fell into an exceedingly muddy and unsavoury shell-hole and lost his bugle! "A" party, on the left, captured three prisoners and bombed several inhabited dug-outs. A machine-gun was also captured. "B," "C," and "D" parties met with little resistance, and saw nothing of the enemy. "E" party bombed northwards towards No. 3 Crater, met with little opposition and captured one prisoner. "F" party had a harder task to the south on the far side of No. 3 Crater, but captured three prisoners and an automatic rifle, which was unfortunately lost when the man carrying it was wounded. "G" party, also moving south, unsuccessfully chased a number of the enemy towards the 75th raiding party.
As soon as the retirement began an undiscovered machine-gun opened up unexpectedly. Fifteen of the enemy were killed, including an officer and two men who resisted all attempts to bring them back after capture. Six prisoners were brought in.
The seventh raid, undertaken by the 87th Battalion, was unsuccessful. The three officers and forty-seven other ranks who made up the party got well away close under the barrage, but on reaching the parapet two small mines were exploded beneath them. In some way the enemy had become aware of the approaching raid, probably owing to an attack carried out by the Division on the left; the element of surprise, the great factor in all successful raids, was thus lost. Heavy fire was directed against the attackers; and after a brisk exchange of bombs it became evident that nothing could be accomplished. The party accordingly withdrew.
These raids, with the one exception noted, were eminently successful. This success was due in no small measure to the very careful preparation made beforehand. The parties involved were withdrawn from the line a week before the raid, all details were carefully worked out, trenches dug to scale, the ground constantly patrolled, and the raiding parties taken over it by night in small groups. The excellent artillery support and the thorough work of the covering parties all contributed to the satisfactory result.
On their arrival in the Somme area the 4th Division was fortunate enough to experience a few days of comparative quiet, with little more than shell-fire and sniping to incommode them while getting themselves shaken down into their new lines. Owing largely to the wretched weather, the conditions underfoot, and the state of the trenches, the operations pending, major and preliminary, were from day to day postponed. In fact, the three senior Canadian Divisions were withdrawn from the area before another attack in force was launched against the blood-drenched barrier of Regina. On October 17th the 4th Division, remaining behind, came under the orders of the II Corps for the purpose of future operations. These operations, in so far as the 4th Division was concerned, began on October 21st.
The general plan of operations was as follows. The II Corps[[1]] was to attack on the front between Courcelette Trench and the River Ancre in order to capture Petit Miraumont, Grandcourt, and at Pierre Divion. Afterwards the passages of the Ancre were to be forced and the II Corps would co-operate with the V Corps by pushing north. There were three Divisions in line, the 18th, 19th, and 39th, from right to left. The dual rôle of the 4th Canadian Division was to protect the right flank of the 18th Division of the II Corps and to safeguard the left flank of the III Corps on the right.
A preliminary operation was assigned to the II Corps before the general action began. This preparatory task was the capture of the Regina Stuff line of trenches, to be undertaken by the 18th, 25th, and 39th Divisions, from right to left. In this operation the 4th Canadian Division would co-operate by effecting the capture of Regina Trench from Courcelette Trench to a point just before the intersection of the Pys Road, thence approximately along an old German trench to join up with the sapheads which were being built by the 10th Canadian Infantry Brigade, under Brigadier-General William Hughes, D.S.O.
The 11th Brigade, on the left, under Brigadier-General V. W. Odlum, D.S.O., undertook the capture of the portion of Regina Trench assigned to the Division. Meanwhile, the 10th Brigade was to co-operate by pushing forward its saps so as to be able to support the 11th Brigade by an enfilading fire. Each Brigade, by the 19th, had completed a very useful sap, close to the junction of their respective lines, up old German trenches to within two-thirds of the distance to Regina. The 11th Brigade placed the 87th and 102nd Battalions in the line, the former on the right, each Battalion having two companies of the 75th in support.
