The parties paraded for the raid with their faces and knees blackened, with their bayonets covered in mud, and with their steel helmets encased in sandbags to which grasses and weeds had been sewn. These precautions were necessary, as the men had to lie out in No Man’s Land, where they would be in danger of being observed by a German sentry, so that they could enter the trenches immediately the torpedoes were exploded.
Ropes were also carried, as it was anticipated that there might be some difficulty in getting the prisoners out of the deep breastwork trenches, and it might be necessary to drag them out.
The men wore Dayfield body-shields to protect them from bomb splinters.
The arms carried were as follows: Officers. 1 revolver, 6 bombs, and 1 electric torch; N.C.O.’s, 1 revolver, 10 bombs, and a bludgeon; 4 bayonet men, rifle and bayonet, 6 bombs, electric torch attached to rifle, 30 rounds of ammunition; 8 throwers, 10 bombs and a bludgeon; 8 spare men, a bludgeon, 10 bombs, and a wire-cutter; blocking party, rifles and bayonets, 30 rounds of ammunition, and 10 bombs.
In the first instance the success of the raid was dependent on the gaps being adequately cut in the wire. At the time many persons thought that General Burn’s scheme of using torpedoes seventy-five feet long was too ambitious. Certainly when the torpedoes were constructed and were seen for the first time, they looked awkward things with which to have dealings in No Man’s Land, being as they were considerably longer than a cricket pitch. When the time arrived the torpedoes were hoisted out of the trenches, and the torpedo parties set off with them. Lieutenant Jenkins had little trouble with his; he reached the selected point in the German entanglement without incident, and placed his torpedo in position. This was difficult work. Here were two parties, each of three men, within 70 yards of the German sentries, forcing a metal tube 3 inches in diameter, 75 feet long, and loaded with ammonal, underneath the German entanglements. Very lights were fired by the enemy continually, illuminating the whole country-side and making the work more hazardous than ever.
It was further impossible to place the torpedoes in position without a certain amount of noise being made, which the German sentries might at any time hear. The whole wire entanglement stood in a mass of rank undergrowth, through which the nose of the torpedo had to be forced. The posts supporting the entanglements were not placed in regular rows, so that occasionally as the torpedo was pushed forward its movement was brought to a standstill by a wooden post standing directly in its way, and its course had to be altered. The lower strands of wire also scraped along the upper surface of the torpedoes, and made a horrible grating noise.
In spite of these difficulties, Lieutenant Jenkins placed his torpedo in position exactly as arranged, and in sufficient time to return to the trench and to lead his party out to a point about thirty yards from the German wire. The party followed the fuse which connected the torpedo to the firing mechanism in the trench, so as to ensure joining up in the right place.
Lieutenant Sainter, on the other hand, was completely out of luck. His torpedo came apart at several of its joints on three separate occasions, and had to be repaired by him in No Man’s Land. Sainter reported that had it not been for the German Very lights, he did not think that he could have managed to repair it. Having finally arrived with it intact at the right place, he had forced it nearly through the German wire when it stuck and could be moved forward no farther. He therefore had to extract it and make a second attempt at a different place. On this occasion he was successful. The operation, however, had taken so long that no time was left for Sainter to return to the trench and lead out his party. The party was therefore ordered to advance, following the fuse as Jenkins’ party had done, until they came upon Sainter. This was done, and the party had joined him and was in position just ten minutes before zero.
At zero the two torpedoes were fired almost simultaneously, leaving gaps clear through the German wire 15 feet broad and 25 yards deep. At the same time the barrage opened. Major A. G. Graham, M.C., commanding the 6th Seaforth Highlanders, writes in his account of the operations: “The barrage opened punctually, and can only be described as perfect. All ranks taking part in the raid were unanimous in their praise. The efficacy of the barrage is borne out by the fact that no German machine-gun fired for forty minutes. The casualties caused by the barrage must have been heavy, as both parties report that on entering the trenches parties of the enemy were seen rushing away from the salient into our barrage.”
Immediately the torpedoes exploded, the raiders rushed through the gaps in the wire and into the enemy’s trenches. The enemy was taken completely by surprise. The first sentry encountered by Sainter’s party was bayoneted in the back, while still staring over the parapet in blank amazement at the curious explosion that had just occurred in front of him.
