Next day, brigade considered the necessity for careful consolidation of the ground gained by the 6th and 7th, but Capt. Creagh intimated that he wished to make his position more secure by capturing the Triangle, a strong triangular redoubt which lay in the grounds of La Signy Farm, and which dominated the post we had just taken. Permission was granted to carry out this enterprise, and once more preparations were rushed forward and orders made out for the operation to be accomplished that night. This time "D" company, temporarily commanded by Lt. Douglas, was selected to provide the attackers. They were back in reserve, close to Batt. H.Q., and on suitable ground for carrying out a quick rehearsal. Also it was decided that the best method of clearing the Boche would be by bombing. The battalion bombing officer was Lieut. Gresty, who belonged to "D" company, and he was put in command of the attacking party, 2nd-Lt. Gorst, at his own request, being detailed to assist him.
The post captured the previous night was the "jumping off" place, and the plan was to work along the enemy trench to the right, clear it by bombing, and so get to the Triangle. The whole operation was a huge success, and never did the eager fighting qualities of the Fleur de Lys show up to prouder advantage than in the display given by "D" company that night. The unexpected direction of approach took the enemy completely by surprise, for our men had not proceeded far before they caught a working party out in the open. There was a short scrap, but most of the poor Jerries had no weapons handy, and they ran off squealing and chattering like a lot of monkeys, leaving their dead and wounded behind. Our men pushed on quickly, anxious to make the fullest possible use of the surprise element, until the northern corner of the Triangle was reached. Here they split up into two parties, Gresty continuing the original direction, and Gorst turning along to the right. The latter party found the trench strongly occupied, but the enemy were so oblivious of what was happening that they were busy "dishing out stew" for the evening meal. When they were surprised a few of them indeed showed plucky fight, hurriedly seizing bombs and throwing them wildly in the direction of the attackers. Others succeeded in grasping their rifles, and Gorst received a nasty bullet wound in the shoulder, but not before he had accounted for one or two Huns with his revolver. Sgt. Horsfield, who understood perfectly the meaning of "Carry on, Sergeant!" continued this part of the show, and the Huns were chased along the trench to the western apex. Here a pitched bombing battle ensued, and very soon the enemy got out and raced across the open in the direction of the farm. Meanwhile, Gresty had led his men over a sort of switch back trench, for it had been so heavily pounded by our Newton T.M's. that it was difficult to make it out at all in the dark. Nevertheless they struggled along, and finding the far corner of the Triangle occupied, quickly bombed the enemy out of it and proceeded to consolidate. At the same time other parties, each of one N.C.O. and six men, had been detailed in the work of manning various posts en route, digging L.G. emplacements, and wiring and constructing of communication trenches. In fact, in a very short time the whole place, which had been a Hun strong point, was swarming with British soldiers busily working to turn round the defences.
