The Duke of Marlborough, before the action began, in person visited each important battery, in order to ascertain the range of the guns. The troops under his command were drawn up in four lines; the infantry being in front, and the cavalry behind, in each line. This arrangement was adopted in order that the infantry, which would get easiest through the streams, might form on the other side, and cover the formation of the cavalry, who might be more impeded. The fire of cannon soon became very animated on both sides, and the infantry advanced to the edge of the rivulets with that cheerful air and confident step which is so often the forerunner of success. On Prince Eugene's side the impediments, however, proved serious; the beds of the rivulets were so broad, that they required to be filled up with fascines before they could be passed by the guns; and when they did get across, they replied without much effect to the French cannon thundering from the heights, which commanded the whole field. At half-past twelve, however, these difficulties were, by great efforts on the part of Prince Eugene and his wing, overcome, and he sent word to Marlborough that he was ready. The English general instantly called for his horse; the troops every where stood to their arms, and the signal was given to advance. The rivulets and marshy ground in front of Blenheim and Unterglau were passed by the first line without much difficulty, though under a heavy fire of artillery from the French batteries; and the firm ground on the slope being reached, the first line advanced in the finest order to the attack – the cavalry in front having now defiled to a side, so as to let the English infantry take the lead. The attack must be given in the words of Dr Hare's Journal.
"Lord Cutts made the first attack upon Blenheim, with the English grenadiers. Brigadier-general Rowe led up his brigade, which formed the first line, and was sustained in the second by a brigade of Hessians. Rowe was within thirty paces of the palisades about Blenheim when the enemy gave their first fire, by which a great many officers and men fell; but notwithstanding this, that brave officer marched direct up to the pales, on which he struck his sword before he allowed his men to fire. His orders were to enter at the point of the bayonet; but the superiority of the enemy, and the strength of their post, rendered this impossible. The first line was therefore forced to retire; Rowe was struck down badly wounded at the foot of the pales; his lieut. – colonel and major were killed in endeavouring to bring him off, and some squadrons of French gens-d'armes having charged the brigade while retiring in disorder, it was partially broken, and one of the colours of Rowe's regiment was taken. The Hessians in the second line upon this advanced briskly forward, charged the squadrons, retook the colour, and repulsed them. Lord Cutts, however, seeing fresh squadrons coming down upon him, sent to request some cavalry should be sent to cover his flank. Five British squadrons accordingly were moved up, and speedily charged by eight of the enemy; the French gave their fire at a little distance, but the English charged sword in hand, and put them to the rout. Being overpowered, however, by fresh squadrons, and galled by the fire which issued from the enclosures of Blenheim, our horse were driven back in their turn, and recoiled in disorder.
"Marlborough, foreseeing that the enemy would pursue this advantage, resolved to bring his whole cavalry across the rivulets. The operation was begun by the English horse. It proved more difficult, however, than was expected, especially to the English squadrons; as they had to cross the rivulet where it was divided, and the meadows were very soft. However, they surmounted those difficulties, and got over; but when they advanced, they were so severely galled by the infantry in Blenheim firing upon their flank, while the cavalry charged them in front, that they were forced to retire, which they did, under cover of Bulow and Bothmer's German dragoons, who succeeded them in the passage. Marlborough, seeing the enemy resolute to maintain the ground occupied by his cavalry, gave orders for the whole remainder of his cavalry to pass wherever they could get across. There was very great difficulty and danger in defiling over the rivulet in the face of an enemy, already formed and supported by several batteries of cannon; yet by the brave examples and intrepidity of the officers, they were at length got over, and kept their ground on the other side. Bulow stretched across, opposite to Oberglau, with the Danish and Hanoverian horse; but near that village they were so vigorously charged by the French cavalry, that they were driven back. Rallying, they were again led to the charge, and again routed with great slaughter by the charges of the horse in front, and the dreadful fire from the inclosures of Blenheim. Nor did the attack on Oberglau to the British right, under Prince Holstein, succeed better; no sooner had he passed the rivulet, than the Irish veterans, posted there, came pouring down upon them, took the prince prisoner, and threw the whole into confusion. Upon this, Marlborough galloped to the spot at the head of some squadrons, followed by three battalions, which had not yet been engaged. With the horse he charged the Irish battalions in flank, and forced them back; the foot he posted himself, and having re-established affairs at that point, returned rapidly to the left, where he found the whole of his corps passed over the streams, and on firm ground on the other side. The horse were drawn up in two lines fronting the enemy; the foot in two lines behind them; and some guns, under Colonel Blood, having been hurried across by means of pontoons, were brought to bear upon some battalions of foot which were intermingled with the enemy's horse, and made great havoc in their ranks.
"It was now past three, and the Duke, having got his whole men ready for the attack, sent to Prince Eugene to know if he was ready to support him. But the efforts of that gallant prince had not been attended with the same success. In the first onset, indeed, his Danish and Prussian infantry had gained considerable success, and taken six guns, and the Imperial cavalry had, by a vigorous charge, broken the first line of the enemy's horse; but they failed in their attack on the second line, and were driven back to their original ground; whereupon the Bavarian cavalry, rushing forward, enveloped Eugene's foot, who were forced to retire, and with difficulty regained their original ground. Half an hour afterwards, Prince Eugene made a second attack with his horse; but they were again repulsed by the bravery of the Bavarian cavalry, and driven for refuge into the wood, in the rear of their original position. Nothing daunted by this bad success, the Prince formed his troops for a third attack, and himself led his cavalry to the charge; but so vigorous was the defence, that they were again repulsed to the wood, and the victorious enemy's dragoons with loud cheers charged the Prussian foot in flank, and were only repelled by the admirable steadiness with which they delivered their fire, and stood their ground with fixed bayonets in front.
"About five the general forward movement was made which determined the issue of this great battle, which till then had seemed doubtful. The Duke of Marlborough, having ridden along the front, gave orders to sound the charge, when all at once our lines of horse moved on, sword in hand, to the attack. Those of the enemy presented their carbines at some distance and fired; but they had no sooner done so than they wheeled about, broke, and fled. The gens-d'armes fled towards Hochstedt, which was about two miles in the rear; the other squadrons towards the village of Sondersheim, which was nearer, and on the bank of the Danube. The Duke ordered General Hompesch, with thirty squadrons, to pursue those who fled to Hochstedt; while he himself, with Prince Hesse and the whole remainder of the cavalry, drove thirty of the enemy's squadrons headlong down the banks of the Danube, which, being very steep, occasioned the destruction of the greater part. Vast numbers endeavoured to save themselves by swimming, and perished miserably. Among the prisoners taken here were Marshal Tallard and his suite, who surrendered to M. Beinenbourg, aid-de-camp to the Prince of Hesse. Marlborough immediately desired him to
