Row upon row of batteries were placed in position behind hedges, or artificially concealed, the barrels of the pieces peeping out from all imaginable lurking places. The Divisional Artillery was situated in the most advanced position, the 18 pr. batteries ranging from within 600 to 1,000 yards of the front line, with the howitzer batteries immediately behind them. On account of our proximity to the enemy, the two brigades had orders to remain silent until the day of the show, and we were only allowed to fire enough rounds to enable us to carefully register the pieces, and this was completed without giving away any of the positions.
All ammunition was conveyed to the guns by night, and was distributed in small quantities near to them. Before long the enemy became alive to the fact that we were contemplating some move, and consequently increased his devastating fire by night, with the result that many dumps in the vicinity were exploded by him. He was bound to hit something, the countryside was so packed with all manner of ammunition. He had no idea, however, of the magnitude of our coming effort, and firmly believed his position to be impregnable, and that it was beyond our power to free ourselves from his grip.
He contented himself with drenching our little valley with chemical shell whenever conditions were favourable, but so accustomed were the men to their gas masks that no serious consequences resulted, although it was distinctly unpleasant to have to pass each night enveloped in these stuffy contrivances, especially as the weather remained hot and oppressive.
The Battery had more than their average share of good fortune throughout these operations, and it is worthy of putting on record that the unit did not sustain a single casualty to either man or horse. This was all the more remarkable as the engineers had constructed a wide plank road, which passed through the centre of our position, and could not be concealed from our foes, who lavishly besprinkled it with shrapnel after dark. Many casualties were caused to the transport, and the Officers’ Mess virtually became an aid-post, where every assistance was rendered the wounded men.
Our sister howitzer battery was lined up alongside of us, and, when the two positions were first inspected, much chaff ensued as to which had the better place, and the men of our battery were certainly all of the opinion that, had the selection devolved upon them, we would unanimously have plumped for the other one. They had no landmarks likely to attract hostile fire, and thus occasion them the unpleasant sensation of living on top of a volcano, while we were slap-bang in the middle of a conspicuous cross road, with a constant stream of traffic coming and going through: yet, so strange and fickle are the fortunes of war that, while we escaped unharmed, our comrades next door suffered a heavy gruelling.
The preliminary bombardment commenced, and continued throughout five days, but, in order to deceive the enemy as to our weight of artillery, not more than fifty per cent. of the guns in the line were allowed to take part at one time. A row of O.P.’s had been constructed on Hill 65, which overlooked the valley and town of Messines. A fine sight was witnessed as that stronghold was gradually reduced to a mere shell by our heavies, which effected extraordinarily good work in smashing the elaborate structures of the enemy’s defence.
The preparations were all that could be desired, and everything was carefully worked out to the minutest detail: not a stone was left unturned to render the operations a complete success. The labour and expense was well rewarded too, for surely no battle ever ran so smoothly from first to last, and it will always be looked back upon by the British soldier as a model of triumphant organisation. The battle only lasted a single day, but in that time the formidable network of trenches was neatly and clearly shorn off, and the enemy, who relied so much on the security of these positions, found himself suddenly pushed down the slope into unsuitable ground, where he could no longer be a menace to us.
The “feet” of our Division were not in the line, being held in reserve, and, as it turned out, they were not called upon at all at this juncture, so well did the course of the battle progress. We were covering the infantry of an English Division, and, on the evening previous to the attack, the troops passed us noiselessly and in perfect order on their way to their various points of assembly. All were in excellent spirits, which augured well for the next day, and a feeling of calm confidence appeared to prevail amongst them. A stream of gas and tear shells was maintained by the foe throughout the night, but it was mostly directed on the zone which contained the battery positions, consequently the infantry was caused little inconvenience.
Early the following morning, shortly before dawn, the attack was heralded by the explosion of the mines, which had been in course of preparation for months beforehand. This was the sign for the guns to open out, and the assault was launched from north of St. Eloi in the Salient to the neighbourhood of Ploegsterte in the south, the men following close in the wake of the now familiar and popular creeping barrage.
The force of the explosions was terrific, and the vibration was felt far and wide; even strong concrete “pill-boxes” were swung to and fro, and the occupants were tossed from side to side as if they were on board ship in a rough sea. Some indication of the colossal nature of these upheavals may be gauged from the fact that the craters were, in some cases, more than 200 ft. in diameter, and that the earth thrown up obliterated every hostile trench in the vicinity, completely burying the unfortunate garrisons who manned them.
