In general, then, we must see the long French line set out in two main bodies. That on the right, under Tallard, had far the greater part of its infantry within or in support of Blenheim,[12] while the cavalry, for the most part, stretched out over the open centre of the field, with Silly’s ten squadrons and what was left of the infantry in reserve. That on the left, under Marcin and the Elector, had its far more numerous cavalry similarly disposed upon its front along the brook, most of its infantry behind, and a great number of these holding the village of Oberglauheim, with cavalry in front of them also. Along the whole line the ninety guns were disposed in a chain, as I have described.
Such being the disposition of the French troops, let us now turn to that of the Imperialists and their English and other allies under Eugene and Marlborough. These appeared within a mile of the French position by seven in the morning, and all that part of their left which lay between the river and the highroad was drawn up within long range of the French artillery somewhat before nine o’clock. But, as a glance at the map will show, their right had to march much further in order to come into line along the course of the Nebel, the course of which leans away from the line of Marlborough’s advance. The difficulty of swampy land under the hills and of woods made the final disposition of the extreme left particularly tardy and tedious, nor was it fully drawn up until just after midday. During all the interval of three hours a brisk cannonade at long range had been proceeding from the guns in front of the French line—and, as nearly always the case with artillery before the modern quick-firer, was doing less damage than the gunners imagined.
When the allied line was finally formed its disposition was as follows:—
On the extreme left six columns of infantry, half of which consisted of British regiments.[13]
These stood immediately opposite the village of Blenheim, and were designed for that attack upon it which Marlborough, in his first intention, desired to make the decisive feature of the action.
Next, towards the main road, came four lines, two of infantry before and behind, and in the midst two parallel lines of cavalry, the foremost of which was British, and in which could be distinguished the mounting and horsemanship of the Scots Greys.[14]
Next again, to the north, and astraddle of the great road, lay the main force; this it will be remarked was drawn up precisely in front of that part in the long French line which was the weakest, and which indeed consisted of little more than the ten squadrons of horse which filled the gap between the Gendarmerie and Oberglauheim. This main force was also drawn up in four great lines; the first of infantry, the two next of cavalry, the rear of infantry: it contained no British troops, and, with the others already mentioned, formed Marlborough’s command. All the rest, along the north and the east, along the left bank of the Nebel, from Willheim up into the woods, and the gorge at the source of the brook, was Eugene’s command—not a third of the whole.
As to the total strength of the allied forces which we must attempt to estimate as we estimated that of the Franco-Bavarians, we know it accurately enough—it was some 52,000 men. The opposing hosts were therefore little different in numbers. But it is of great importance to note the disproportion of cavalry. In that of the Imperialists under Marlborough and Eugene, not only was the cavalry better mounted and free from the fatigue and disease that had ravaged Tallard’s horses, but it was nearly double in number that of its opponents. On the other hand, the artillery of the allies was far inferior. Only sixty-six guns at the most[15] were opposed to the French ninety.
Blenheim, in the issue, turned out to be a cavalry battle—a battle won by cavalry, and its effect clinched by cavalry. The poor rôle played by the guns and the inability of the French to make use of their numerical superiority in this arm was a characteristic of the time, which had not yet learnt to use the cannon as a mobile weapon.
