One pill-box in particular on the crest of the hill maintained such a murderous fire that the attacking company of the Princess Pat's was brought to a halt upon the slope of the hill, with every officer and N.C.O. shot down, and the men remaining seeking what cover they could, unable to advance and unwilling to retreat. All this time MacKenzie had been ploughing forward with his guns, seeking good positions and finding them, rendering a German emplacement untenable, wiping out some hostile formation that threatened a sudden counter-attack, and endeavouring to keep down the heavy fire of the Germans immediately before our advancing infantry. Noting the hesitation of our men on the slope of the hill, he left a corporal in charge of his guns, and made his way through the heavy fire to our fellows in their terribly exposed position. The Company had been very hard hit, two thirds of its effectives were gone, but still the men were determined enough. Taking command of the company, he cheered them by his good spirits, and instantly set about arranging a plan for the downfall of the pill-box above them. Not only was there the pill-box to deal with, but the upper hill was a veritable nest of machine-guns, and MacKenzie had to make a daring reconnaissance before he could effect a suitable scheme of attack. Detailing small parties, he sent them off to work their way round the flanks, overcoming any hostile resistance they might encounter, and to be prepared at a given moment to make an attack from the rear upon the pill-box that was holding up the advance. Then he arranged the frontal attack, choosing himself to lead a small party of men directly up the slope to the fort, while the remainder of his men attacked the same front from a different angle. At the word they went forward, MacKenzie leading the forlorn hope on the most exposed front of the attack. It was not possible to win through such fire unharmed, and he was shot through the head and killed at the moment of the capture of the pill-box by the flanking parties he had detailed. One may hope that he saw his object attained. This pill-box, in its dominating position upon the crest of the hill, commanded the lines of our attack for many hundred yards. By its capture Lieutenant MacKenzie and his men saved the lives of many soldiers, and enabled the successful consolidation of our objectives upon the whole local front.
