Cutts made his attack on Blenheim with all the fury which earned for him the nickname of the Salamander. Against the enormous force that was massed in the village it was scarcely possible that he should actually succeed, but he prevented any troops from being withdrawn towards the centre. Here also the vicissitudes of the action were great. The first line of English infantry advanced right up to the palisades covering the village before they fired a shot. While vainly trying to force their way through the defences they were suddenly charged in flank by some French cavalry, and would have been routed but for some Hessian cavalry, which drove back the enemy. A fierce and confused cavalry fight followed, into which was drawn every squadron that Cutts could command, but with no decisive result. Meanwhile Marlborough's centre had been slowly crossing the Nebel, covered by the artillery on the high ground east of the stream, which approached much nearer to it than on the French side. The passage was begun opposite Unterglauheim by the infantry of General Churchill, Marlborough's brother. As soon as they could begin to form on the further bank cavalry pushed across after them, and though charged by the first line of Tallard's cavalry, and driven back, they were rescued by the infantry, now fairly formed, and made good their position. As more and more cavalry crossed the Nebel they extended to the right towards Oberglauheim, which was held in force by the right of Marsin's army. His cavalry fully held their own, driving some of the Danish and Hanoverian squadrons back across the Nebel. The infantry of Marlborough's right now began to cross above Oberglauheim, but being promptly attacked by the French infantry out of that village, the Irish brigade conspicuous among them, suffered heavy loss, and would have been defeated, but for reinforcements brought up by Marlborough in person, which restored the balance.
The time was now come for Marlborough to deliver the decisive attack. His whole army was across the stream, and formed, the cavalry in two lines, the infantry in support with intervals between the battalions, so that the squadrons if repulsed might pass through. His artillery, advanced to the Nebel, played upon the stationary French until the last moment. Tallard had done, could do, nothing to meet the coming storm, except to bring up his reserve infantry, nine battalions, and mingle them with his cavalry. About five o'clock the signal was given, and Marlborough led his horsemen, some 8000 strong, up the gentle slope to the French position. The first charge did not succeed, but some infantry and artillery, brought up in support, took up the action. The French did not venture to charge in their turn, though they had ample numbers for doing so: apparently the feebleness of Tallard was felt throughout his army, and so the last chance was thrown away. Marlborough's second charge completely broke the French cavalry: the infantry intermixed with them were cut to pieces or surrendered. Tallard in vain tried to re-form his cavalry, in order to cover the retreat of his infantry from Blenheim: they did not even stand another charge, but fled in confusion, some westwards, some towards the Danube. Detaching part of his force to pursue the former, Marlborough drove the latter upon the river. Tallard himself, with such of the fugitives as did not try to swim the Danube, was compelled to surrender. Meanwhile General Churchill, advancing in rear of the victorious cavalry, had encircled Blenheim, where nearly 12,000 French, mostly infantry, were still cooped up. After vain attempts to cut their way out, the whole mass surrendered: they had been utterly wasted by the mismanagement of their general.
It was the practice in Marlborough's day to count armies by the number of battalions and squadrons; and as those of course varied in strength, through casualties as well as through unequal original numbers, calculations based on them are a little uncertain. There is very fair agreement as to the battalions and squadrons engaged on both sides, from which it may be reasonably inferred that the allies had about 52,000 men (9000 only being English), of which nearly 20,000 were cavalry, and the French about 56,000, of whom perhaps 18,000 were cavalry. In artillery the French had a decided superiority. With this advantage, and with a position difficult to assail effectually, they ought to have been well able to hold their own. The miserable tactics of Tallard however did more than throw away this advantage. The opinion has been expressed that 4000 men were amply sufficient to hold Blenheim: Tallard left 13,000 there all through the day. The difference, 9000, more than neutralised the French superiority in infantry, and left the allies their preponderance in cavalry. Moreover Eugene had apparently rather inferior forces to those immediately opposed to him. Thus Marlborough was able to carry out, to some extent at least, the cardinal maxim of bringing superior forces to bear at the decisive point.
As might be inferred from the severity of the fighting, the victory cost the allies dear, no less than 4500 killed and 7500 wounded. The French loss was enormous: fully a quarter of their army surrendered themselves prisoners, a still larger number were killed and wounded, or were drowned in attempting to pass the Danube. Their camp and nearly all their artillery fell into the hands of the victors. Roughly speaking it may be said that Tallard's army was annihilated: Marsin's, though it suffered severely, made good its retreat without being disorganised.
Without going so far as Sir E. Creasy, who ranks Blenheim among the fifteen decisive battles of the world, we may still say that its moral results were even more important than the heavy material blow inflicted on France. For half a century France had been much more than the first military nation in Europe. Thanks in the first place to Turenne, but also to the organising skill of Louvois and the engineering genius of Vauban, Louis XIV. had developed a power which, wielded as it was by a despot steadily bent on selfish aggrandisement, had been fully a match for coalition after coalition. A succession of great generals carried on the traditions of Turenne: they were pitted against enemies who on the whole were inferior in skill, in resources, above all in homogeneity. The world had almost come to believe in the natural and permanent military superiority of France, and to accept Louis XIV. on his own estimate of himself. The news of Blenheim broke the spell: the domination of France was over. Louis himself had to admit that he was mortal: during the remainder of the war he stood substantially on the defensive, trying to retain or to recover territories over which he or his grandson, the king of Spain, had some claim, but no longer dreaming of crushing his antagonists. The power of France was by no means broken as yet; thanks to the difficulties inherent in working a coalition, she held her ground for several years more, but the tide, which had turned at Blenheim, set on the whole steadily against her.
Believing France to be more exhausted than she in fact was, Marlborough hoped to achieve great things in 1705 by attacking France from the side of the Moselle. The reluctance of his allies however kept his army so small that he was powerless. Villars, the ablest living French general, was opposed to him with superior forces, and with orders to avoid a battle. After vainly trying for six weeks to find an opportunity—a direct attack on Villars in an intrenched position being beyond his strength—Marlborough returned to the Netherlands, where the incapable Villeroi lay behind a great line of almost continuous fortifications from Antwerp to Namur. It was the fashion of the age to construct these elaborate defences, always open to two fatal objections, that they deprived the army holding them of all mobility, and that they became useless if broken through at any point. So long as the enemy was content to play the game in the fashion that best suited the defence, or was so hindered by bad roads and lack of subsistence that he found it difficult to move promptly, such lines might serve their purpose; and if from the nature of the country they could not be turned, an enemy might deem it too hazardous to break through them. But from Turenne onwards skilful generals turned or pierced them whenever they seriously tried; and Marlborough's easy success in breaking through the French lines at what was deemed their strongest point was a very striking proof of their inutility.[59] Had it not been for the persistent opposition of the Dutch to any decisive action, Marlborough, advancing on Brussels, would have fought a great battle very nearly on the field of Waterloo. Hampered by the Dutch, he could achieve nothing; and the year 1705, though eventful in other parts of the vast theatre of war, ended in the Netherlands much as it began.
The next year Marlborough formed a plan even more far-reaching and audacious than that which had been brought to so triumphant a conclusion on the field of Blenheim. The French in northern Italy had been pressing their enemies hard: well led by Vendôme, they had gone very near to conquering Piedmont entirely. Marlborough dreamed of marching his own army down into Italy, and relieving the duke of Savoy. Fortunately perhaps for his fame, he found the obstacles insurmountable, and remained in the Netherlands,[60] where the incapable Villeroi soon played into his hands. Believing that Marlborough's army was not yet concentrated, and that therefore he could fight a battle to advantage, Villeroi moved from his intrenched camp at Louvain in the direction of Liège, not far from which city were Marlborough's head-quarters. As a matter of fact, Marlborough was not only ready for action, but slightly superior in numbers to Villeroi, and he promptly moved towards the sources of the two small rivers known as the great and little Gheet, in order that Villeroi might not protect himself behind them, if he discovered that he had no chance of fighting with the weight of numbers on his side. Villeroi however was in no way desirous of avoiding a battle, and took up a position facing eastwards, near the source of the little Gheet.
The field of Ramillies is the highest ground in Brabant, and, as is apt to be the case in flat countries where the fall of the ground is extremely gradual, there was a great deal of morass, in some places impassable. Immediately at the source of the little Gheet is the small village of Ramillies; about two miles to the north of it lies another village, Autre Eglise, on the west of the stream, the whole course of which, so far, is very marshy. Just south of Ramillies runs from east to west an old Roman road known as Brunehaut's road, with the small river Mehaigne beyond it, and between the road and the Mehaigne, about south of Ramillies, is the village of Tavière. Villeroi's position was on the higher ground behind the little Gheet, whence the slope to the great Gheet, about two miles further west, is rather greater, and along which runs the road by which Villeroi had come from Judoigne on the great Gheet. His left was behind Autre Eglise, his centre behind Ramillies, his right on a barrow called the tomb of Ottomond, close above the Roman road, with a small force thrown forward into Tavière. The allied army, marching from the east, arrived in front of this position about noon (May 23, 1706). Marlborough at once saw the opportunity which was afforded him by half of the French front being covered by the morasses of the little Gheet. The left was in fact almost, not quite, unassailable; but inasmuch as the road to Judoigne, Villeroi's most direct line of retreat, ran in rear of the left, this flank was, apart from the obstacle of the marshes, the one which it would be most advantageous for an enemy to attempt to turn. Hence Villeroi was easily led by demonstrations to strengthen his left wing. Marlborough on the other hand, secure that no counter-attack could be effectively made on his right through the marshes, could leave there only just troops enough to continue the demonstration, and mass nearly his whole force towards the left. The curve of the ground enabled him to do this unobserved by Villeroi, who had gone in person to his left wing, on the attack in that quarter being begun. The French were driven out of Tavière after a short struggle: then the Dutch and German cavalry charged the famous musketeers, who were posted nearly behind Tavière. They broke the first line, but being attacked by the second line when in the confusion of a successful charge, were driven back. Marlborough however came to their support, with the cavalry which he had withdrawn from the right wing; the musketeers were broken, outflanked, and driven in towards the centre, while the allies occupied the tomb of Ottomond, whence their guns could enfilade the whole French line. Meanwhile a fierce contest had been raging in the village of Ramillies. The French there held their ground, though unable to repulse the assailants, until taken in flank from the tomb of Ottomond. The battle was now virtually won: the whole of the French centre and right were crowded together in utter confusion. Villeroi in vain tried to form a new line, with his left still on Autre Eglise, thrown back nearly at a right angle to his former line. Such an attempt, desperate at best in face of a victorious enemy, was rendered entirely hopeless by the ground being blocked with the baggage and ammunition waggons. Some English troops, making their way as best they could through the swamps, assailed the French left behind Autre Eglise, and completed the rout. Seldom, in modern times, has a great victory been so cheaply purchased; the total of killed and wounded on the side of the allies fell considerably short of 4000 men. The loss of the French was naturally greater: but the blow to them was far heavier than the figures would imply. They lost nearly all their artillery and baggage; and most of the army was for the time dissolved into a mob of fugitives, among whom thousands of Walloons, unwilling soldiers at best, took the opportunity of dispersing to their homes. The French army, as at Vittoria, almost ceased for a while to exist as an army, and was even longer in being restored to efficiency. In the completeness of the disorganisation inflicted by defeat, Ramillies has perhaps no superior in modern times except Waterloo.
