By this time the vanguard of the allies was close to his outposts. About half a mile in advance of his army was encamped a brigade named from the province of Bourbonnais. These troops had to bear the first brunt of the onset. Amazed and panicstricken, they were swept away in a moment, and ran for their lives, leaving their tents and seven pieces of cannon to the assailants.
Thus far William's plans had been completely successful but now fortune began to turn against him. He had been misinformed as to the nature of the ground which lay between the station of the brigade of Bourbonnais and the main encampment of the enemy. He had expected that he should be able to push forward without a moment's pause, that he should find the French army in a state of wild disorder, and that his victory would be easy and complete.
But his progress was obstructed by several fences and ditches;there was a short delay; and a short delay sufficed to frustrate his design. Luxemburg was the very man for such a conjuncture. He had committed great faults; he had kept careless guard; he had trusted implicitly to information which had proved false; he had neglected information which had proved true; one of his divisions was flying in confusion; the other divisions were unprepared for action. That crisis would have paralysed the faculties of an ordinary captain; it only braced and stimulated those of Luxemburg. His mind, nay his sickly and distorted body, seemed to derive health and vigour from disaster and dismay. In a short time he had disposed every thing. The French army was in battle order. Conspicuous in that great array were the household troops of Lewis, the most renowned body of fighting men in Europe; and at their head appeared, glittering in lace and embroidery hastily thrown on and half fastened, a crowd of young princes and lords who had just been roused by the trumpet from their couches or their revels, and who had hastened to look death in the face with the gay and festive intrepidity characteristic of French gentlemen. Highest in rank among these highborn warriors was a lad of sixteen, Philip Duke of Chartres, son of the Duke of Orleans, and nephew of the King of France. It was with difficulty and by importunate solicitation that the gallant boy had extorted Luxemburg's permission to be where the fire was hottest. Two other youths of royal blood, Lewis Duke of Bourbon, and Armand Prince of Conti, showed a spirit worthy of their descent. With them was a descendant of one of the bastards of Henry the Fourth, Lewis Duke of Vendome, a man sunk in indolence and in the foulest vice, yet capable of exhibiting on a great occasion the qualities of a great soldier. Berwick, who was beginning to earn for himself an honourable name in arms, was there; and at his side rode Sarsfield, whose courage and ability earned, on that day, the esteem of the whole French army. Meanwhile Luxemburg had sent off a pressing message to summon Boufflers. But the message was needless. Boufflers had heard the firing, and, like a brave and intelligent captain, was already hastening towards the point from which the sound came.
Though the assailants had lost all the advantage which belongs to a surprise, they came on manfully. In the front of the battle were the British commanded by Count Solmes. The division which was to lead the way was Mackay's. He was to have been supported, according to William's plan, by a strong body of foot and horse.
Though most of Mackay's men had never before been under fire, their behaviour gave promise of Blenheim and Ramilies. They first encountered the Swiss, who held a distinguished place in the French army. The fight was so close and desperate that the muzzles of the muskets crossed. The Swiss were driven back with fearful slaughter. More than eighteen hundred of them appear from the French returns to have been killed or wounded. Luxemburg afterwards said that he had never in his life seen so furious a struggle. He collected in haste the opinion of the generals who surrounded him. All thought that the emergency was one which could be met by no common means. The King's household must charge the English. The Marshal gave the word; and the household, headed by the princes of the blood, came on, flinging their muskets back on their shoulders. "Sword in hand," was the cry through all the ranks of that terrible brigade: "sword in hand. No firing. Do it with the cold steel." After a long and desperate resistance the English were borne down. They never ceased to repeat that, if Solmes had done his duty by them, they would have beaten even the household. But Solmes gave them no effective support. He pushed forward some cavalry which, from the nature of the ground, could do little or nothing. His infantry he would not suffer to stir.
