The moment came when the greater part of Marlborough's cavalry had crossed, but before they had fully formed upon the further bank. While they were still in the disorder of forming, the French cavalry upon their left--that is, between the main road and Blenheim--charged down the slight slope, and something like a dismemberment of the whole of Marlborough's mounted line began. It was checked for a moment by the fire of the British infantry, during which check Marlborough brought over certain Danish and Hanoverian squadrons which had remained upon the further bank. But the French charged again, and though infantry of Marlborough's which was pouring over the stream up beyond the stone bridge came up in time to prevent a complete break down, the moment was critical in the extreme. All Marlborough's centre was pressed and shaken; a further spurt against it and it would break. It was such a moment as commanders of rapid decision and quick eye have always seized; and if it be asked how Tallard should have seized it, the answer is that there were French guns to mass, there was French infantry in Blenheim unused, and more in reserve behind Blenheim wholly useless. There were the ten squadrons of Tallard's second line of cavalry under Silly, a couple of hundred yards away, to be summoned in a few moments. Rapid decision and keen sight of this sort would have done the business; but Tallard was slow of perception; an excellent strategist, but short-sighted and a great gentleman; one, moreover, who had advanced by favour rather than by intrigue. He lost the moment. Marlborough's cavalry managed to form, struggling beyond the brook, and the last final phase of the action was at hand--for Marlborough's cavalry would reiterate that general lesson which the whole battle teaches, to wit, that the horse of the allies was not only far stronger numerically, but far better trained than the French cavalry before them, and, with equal chances, must destroy it. Tallard, by missing his moment, had permitted those equal chances to be restored. Even so, yet one other last accident favoured the French. The hour was about five, or rather later in the mid-afternoon. In order to be able to form his cavalry beyond the Nebel, Marlborough wanted to have a clear right flank, and with that object he had launched from 6000 to 7000 Hanoverians against Oberglauheim. The excellent infantry of Blainville, less in numbers, emerged from the village, threw the Hanoverians into gross disorder, and captured their commander. At this point there was beginning to be a rout. This new French success, properly followed up, would again have had a chance to break the allied centre at its weakest point, just at the link where Marlborough joined on to Eugene.
