Meanwhile Würtemberg's batteries had opened fire, and a cunning officer of the Royal Scots was laying his guns with admirable precision. French batteries hastened into position to reply to them with as deadly an aim, and for an hour and a half the rival guns thundered against each other unceasingly. All this time the French battalions kept massing themselves thicker and thicker on Luxemburg's right, and the front line was working with desperate haste, felling trees, making breastworks, and lining the hedges and copses while yet they might. But still Würtemberg's division remained unsupported, and the precious minutes flew fast. William, or his staff for him, had made a serious blunder. Intent though he was on fighting a battle with his infantry only, he had put all the cavalry of one wing of his army before them on the march, so that there was no room for the infantry to pass. Fortunately six battalions had been intermixed with the squadrons of this wing, and these were now with some difficulty disentangled and sent forward. Cutts's, Mackay's, Lauder's, and the Twenty-sixth formed up on Würtemberg's right, with the Sixth and Twenty-fifth in support; and at last, at half-past twelve, Würtemberg gave the order to attack. His little force shook itself up and pressed forward with eagerness. The Guards and Danes on the extreme left, being on the same ridge with the enemy, were the first that came into action. Pushing on under a terrible fire at point-blank range from the French batteries, they fell upon Bourbonnois and the dragoons, beat them back, captured their guns, and turned them against themselves. On their right the Royal Scots, Twenty-first, and Fitzpatrick's plunged down into the ravine into closer and more difficult ground, past copses and hedges and thickets, until a single thick fence alone divided them from the enemy. Through this they fired at each other furiously for a time, till the Scots burst through the fence with their Colonel at their head and swept the French before them. Still further to the right, the remaining regiments came also into action; muzzle met muzzle among the branches, and the slaughter was terrible. Young Angus, still not yet of age, dropped dead at the head of the Cameronians, and the veteran Mackay found the death which he had missed at Killiecrankie. He had before the attack sent word to General Count Solmes, that the contemplated assault could lead only to waste of life, and had been answered with the order to advance. "God's will be done," he said calmly, and he was among the first that fell.
