"Meanwhile Prince Eugene, by a fourth attack, succeeded in driving the Elector of Bavaria from his position; and the Duke, seeing this, sent orders to the squadrons in pursuit, towards Morselingen, to wheel about and join him. All this while the troops in Blenheim had been incessantly attacked, but it still held out and gave employment to the Duke's infantry. The moment the cavalry had beaten off that of the enemy, and cleared the field between the two villages of them, General Churchill moved both lines of foot upon the village of Blenheim, and it was soon surrounded so as to cut off all possibility of escape except on the side next the Danube. To prevent the possibility of their escape that way, Webb, with the Queen's regiment, took possession of a barrier the enemy had constructed to cover their retreat, and, having posted his men across the street which led to the Danube, several hundreds of the enemy, who were attempting to make their escape that way, were made prisoners. The other issue to the Danube was occupied in the same manner by Prince George's regiment: all who came out that way were made prisoners or driven into the Danube. Some endeavoured to break out at other places, but General Wood, with Lord John Hay's regiment of grey dragoons (Scots Greys) immediately advanced towards them, and, cantering up to the top of a rising ground, made them believe they had a larger force behind them, and stopped them on that side. When Churchill saw the defeat of the enemy's horse decided, he sent to request Lord Cutts to attack them in front, while he himself attacked them in flank. This was accordingly done; the Earl of Orkney and General Ingoldesby entering the village at the same time, at two different places, at the head of their respective regiments. But so vigorous was the resistance made by the enemy, especially at the churchyard, that they were forced to retire. The vehement fire, however, of the cannon and howitzers, which set fire to several barns and houses, added to the circumstance of their commander, M. Clerambault, having fled, and their retreat on all sides being cut off, led to their surrendering at discretion, to the number of six-and-twenty battalions. Thus concluded this great battle, in which the enemy had 5900 more than the Allies,12 and the advantage of a very strong position, difficult of attack."13
In this battle Marlborough's wing lost 3000 men, and Eugene's the same number, in all 6000. The French lost 13,000 prisoners, including 1200 officers, almost all taken by Marlborough's wing, besides 34 pieces of cannon, 26 standards, and 90 colours; Eugene took 13 pieces. The killed and wounded were 14,000 more. But the total loss of the French and Bavarians, including those who deserted during their calamitous retreat through the Black Forest, was not less than 40,000 men,14 a number greater than any which they sustained till the still more disastrous day of Waterloo.
This account of the battle, which is by far the best and most intelligible which has ever yet been published, makes it quite evident to what cause the overwhelming magnitude of this defeat to the French army was owing. The strength of the position consisted solely in the rivulets and marshy grounds in its front; when they were passed, the error of Marshal Tallard's disposition of his troops was at once apparent. The infantry was accumulated in useless numbers in the villages. Of the twenty-six battalions in Blenheim, twenty were useless, and could not get into action, while the long line of cavalry from thence to Oberglau was sustained only by a few battalions of foot, incapable of making any effective resistance. This was the more inexcusable, as the French, having sixteen battalions of infantry more than the Allies, should at no point have shown themselves inferior in foot soldiers to their opponents. When the curtain of horse which stretched from Blenheim to Oberglau was broken through and driven off the field, the 13,000 infantry accumulated in the former of these villages could not avoid falling into the enemy's hands; for they were pressed between Marlborough's victorious foot and horse on the one side, and the unfordable stream of the Danube on the other. But Marlborough, it is evident, evinced the capacity of a great general in the manner in which he surmounted these obstacles, and took advantage of these faulty dispositions; resolutely, in the first instance, overcoming the numerous impediments which opposed the passage of the rivulets, and then accumulating his horse and foot for a grand attack on the enemy's centre, which, besides destroying above half the troops assembled there, and driving thirty squadrons into the Danube, cut off, and isolated the powerful body of infantry now uselessly crowded together in Blenheim, and compelled them to surrender.
Immense were the results of this transcendent victory. The French army, lately so confident in its numbers and prowess, retreated "or rather fled," as Marlborough says, through the Black Forest; abandoning the Elector of Bavaria and all the fortresses on the Danube to their fate. In the deepest dejection, and the utmost disorder, they reached the Rhine, scarce twelve thousand strong, on the 25th August, and immediately began defiling over by the bridge of Strasburg. How different from the triumphant army, which with drums beating, and colours flying, had crossed at the same place six weeks before! Marlborough, having detached part of his force to besiege Ulm, drew near with the bulk of his army to the Rhine, which he passed near Philipsburg on the 6th September, and soon after commenced the siege of Landau, on the French side; Prince Louis with 20,000 men forming the besieging force, and Eugene and Marlborough with 30,000 the covering army. Ulm surrendered on the 16th September, with 250 pieces of cannon, and 1200 barrels of powder, which gave the Allies a solid foundation on the Danube, and effectually crushed the power of the Elector of Bavaria, who, isolated now in the midst of his enemies, had no alternative but to abandon his dominions, and seek refuge in Brussels, where he arrived in the end of September. Meanwhile, as the siege of Landau was found to require more time than had been anticipated, owing to the extraordinary difficulties experienced in getting up supplies and forage for the troops; Marlborough repaired to Hanover and Berlin to stimulate the Prussian and Hanoverian cabinets to greater exertions in the common cause, and he succeeded in making arrangements for the addition of 8000 more Prussian troops to their valuable auxiliary force, to be added to the army of the Imperialists in Italy, which stood much in need of reinforcement. The Electress of Bavaria, who had been left Regent of that State in the absence of the Elector in Flanders, had now no resource left but submission; and a treaty was accordingly concluded in the beginning of November, by which she agreed to disband all her troops. Trarbach was taken in the end of December; the Hungarian insurrection was appeased; Landau capitulated in the beginning of the same month; a diversion which the enemy attempted on Trêves was defeated by Marlborough's activity and vigilance, and that city put in a sufficient posture of defence; and the campaign being now finished, that accomplished commander returned to the Hague, and London, to receive the honour due for his past services, and urge their respective cabinets to the efforts necessary to turn them to good account.
Thus by the operations of one single campaign was Bavaria crushed, Austria and Germany delivered. Marlborough's cross-march from Flanders to the Danube, had extricated the Imperialists from a state of the utmost peril, and elevated them at once to security, victory, and conquest. The decisive blow struck at Blenheim, resounded through every part of Europe; it at once destroyed the vast fabric of power which it had taken Louis XIV., aided by the talents of Turenne, and the genius of Vauban, so long to construct. Instead of proudly descending the valley of the Danube, and threatening Vienna, as Napoleon afterwards did in 1805 and 1809, the French were driven in the utmost disorder across the Rhine. The surrender of Trarbach and Landau gave the Allies a firm footing on the left bank of that river. The submission of Bavaria deprived the French of that great outwork, of which they have made such good use in their German wars, the Hungarian insurrection, deprived of the hoped-for aid from the armies on the Rhine, was pacified. Prussia was induced by this great triumph to co-operate in a more efficient manner in the common cause; the parsimony of the Dutch gave way before the tumult of success; and the empire, delivered from invasion, was preparing to carry its victorious arms into the heart of France. Such results require no comment; they speak for themselves, and deservedly place Marlborough in the very highest rank of military commanders.
