siege, and approached the covering army closely, as if with that design. But Marlborough persevered in his design; for, to use his own words, "The Elector of Bavaria says, he is promised a hundred and ten battalions, and they are certainly stronger in horse than we. But even if they had greater numbers, I neither think it is their interest nor their inclination to venture a battle; for our men are in heart, and theirs are cowed."[17] Considerable difficulties were experienced in the first instance in getting up the siege equipage, in consequence of the inundations which were let loose; but a drought having set in, when the blockade began, in the beginning of August, these obstacles were erelong overcome, and on the 9th August the besiegers' fire began, while Marlborough took post at Helchin to cover the siege. On the 18th, the fire of the breaching batteries had been so effectual, that it was deemed practicable to make an assault on the covered way. As a determined resistance was anticipated, the Duke repaired to the spot to superintend the attack. At seven in the evening, the signal was given by the explosion of two mines, and the troops, the English in front, rushed to the assault. They soon cut down the palisades, and, throwing their grenades before them, erelong got into the covered way; but there they were exposed to a dreadful fire from two ravelins which enfiladed it. For two hours they bore it without flinching, labouring hard to erect barricades, so as to get under cover; which was at length done, but not before fourteen hundred of the brave assailants had been struck down. This success, though thus dearly purchased, was however decisive. The establishment of the besiegers in this important lodgement, in the heart as it were of their works, so distressed the enemy, that on the 22d they hoisted the white flag, and capitulated, still 4300 strong, on the following day. The reduction of this strong and celebrated fortress gave the most unbounded satisfaction to the Allies, as it not only materially strengthened the barrier against France; but having taken place in presence of the Duke de Vendôme and his powerful army, drawn together with such diligence to raise the siege, it afforded the strongest proof of the superiority they had now acquired over their enemy in the field.[18]
