The Great British Battles. Hilaire Belloc

In the hills to the north of the Danube, and one day’s march from the town of Ulm, were now concentrated the forces of Marlborough and the Duke of Baden. They were advancing, ninety-six battalions strong, with two hundred and two squadrons and forty-eight guns: in all, say, somewhat less than 70,000 men.

       Marcin’s front from the neighbourhood of Ulm to Donauwörth.

      At Ulm lay Marcin, and in touch with him, forming part of the same army, the Elector of Bavaria was camped somewhat further down the river, near Lauingen.

      The combined forces of Marcin and the Elector of Bavaria numbered, all told, some 45,000 men, and their inferiority to the hostile armies, which had just effected their junction north of Ulm at Ursprung, was the determining factor in what immediately followed.

      Marcin crossed the Danube to avoid so formidable a menace, and took up his next station behind the river at Leipheim, watching to see what Marlborough and the Duke of Baden would do. The Elector of Bavaria, in command of the bridge at Lauingen, stood fast, ready to retire behind the stream. The necessity of such a retreat was spared him. The object of his enemies was soon apparent by the direction their advance assumed.

For the immediate object of Marlborough and Baden was not an attack upon the inferior forces of the Elector and Marcin, but, for reasons that will presently be seen, the capture of Donauwörth, and their direct march upon Donauwörth took them well north of the Danube. On the 26th, therefore, Marcin thought it prudent to recross the Danube. He and the Elector joined forces on the north side of the Danube, and lay from Lauingen to Dillingen, commanding two bridges behind them for the crossing of the stream, and fairly entrenched upon their front. Meanwhile their enemies, the allies, passed north of them at Gingen. This situation endured for three days.4

      When it was apparent that the allied forces of the English general and the Duke of Baden intended to make themselves masters of Donauwörth (and the Elector of Bavaria could have no doubt of their intentions after the 29th of July, when their march eastward from Gingen was resumed), a Franco-Bavarian force was at once detached by him to defend that town, and it is necessary henceforward to understand why Donauwörth was of such importance to Marlborough’s plan.

      It was his intention to enter Bavaria so as to put a pressure upon the Elector, whose immediate and personal interests were bound up with the villages and towns of his possessions. The Elector could not afford to neglect the misfortunes of its civilian inhabitants, even for the ends of his own general strategy; still less could he sacrifice those subjects of his for the strategic advantage of the King of France and his marshal.

      This Marlborough knew. To enter Bavaria, to occupy its towns (only one of which, Ingolstadt, was tolerably fortified), and if possible to take its capital, Munich, had been from its inception the whole business and strategic motive of his march to the Danube.

      But if Marlborough desired to enter Bavaria, Donauwörth was the key to Bavaria from the side upon which he was approaching.

      This word “key” is so often used in military history, without any explanation of it which may render it significant to the reader, that I will pause a moment to show why Donauwörth might properly be called in metaphor the “key” of Bavaria to one advancing from the north and west.

      Bavaria could only be reached by a general coming as Marlborough came, on condition of his possessing and holding some crossing-place over the Danube, for Marlborough’s supplies lay north of that river (principally at Nördlingen), and the passing of the enormous supply of an army over one narrow point, such as is a bridge over such an obstacle as a broad river, demands full security.

      It will further be seen from the map that yet another obstacle, defending Southern Bavaria and its capital towards the west, as the Danube does towards the north, is the river Lech; a passage over this was therefore also of high importance to the Duke of Marlborough and his allies. Now, a man holding Donauwörth can cross both rivers at the same time unmolested, for they meet in its neighbourhood.

      Further, Donauwörth was a town amply provisioned, full of warehouse room, and in general affording a good advanced base of supply for any army marching across the Danube. It afforded an opportunity for concentration of supplies, it contained waggons and horses and food. Supplies, it must be remembered, were the great difficulty of each of the two opposed forces, in this moving of great numbers of men east of the Black Forest, in a comparatively poor country, largely heath and forest, and ill populated.

No serious permanent defences, such as could delay the capture of the town, surrounded Donauwörth; but up above it lies a hill, called from its shape “the Schellenberg” or “Bell Hill.” This hill is not isolated, but joins on the higher ground to its north by a sort of flat isthmus, which is level with the summit or nearly so.5

      The force which, on perceiving the Duke of Marlborough’s intention of capturing Donauwörth, the Elector of Bavaria very rapidly detached to defend that town, was under the command of Count d’Arco; it consisted of two regiments of cavalry and about 10,000 infantry (of whom a quarter were French). D’Arco had orders to entrench the hill above the town as rapidly as might be and to defend it from attack; for whoever held the Schellenberg was master of Donauwörth below. But the Elector could only spare eight guns for this purpose from his inferior forces.

      Upon the 2nd of July, in the early morning, Marlborough, by one of those rapid movements which were a prime element in his continuous success, marched before dawn with something between seven and eight thousand infantry carefully chosen for the task and thirty-five squadrons of horse for the attack on the Schellenberg. It was Marlborough’s alternate day of command.

      With all his despatch, he could not arrive on the height of the hill nor attack its imperfect but rapidly completing works until the late afternoon. It is characteristic of his generalship that he risked an assault with this advance body of his without waiting for the main part of the army under the Duke of Baden to come up. With sixteen battalions only, of whom a third were British, he attempted to carry works behind which a force equal to his own in strength was posted. The risk was high, for he could hardly hope to carry the works with such a force, and all depended upon the main body coming up in time. There was but an hour or two of daylight left.

      The check which Marlborough necessarily received in such an attempt incidentally gave proof of the excellent material of his troops. More than a third of these fell in the first furious and undecided hour. They failed to carry the works. They had already once begun to break and once again rallied, but had suffered no final dissolution under the ordeal—though it was both the first to which the men were subjected during this campaign, and probably also the most severe of any they were to endure.

      Whether they, or indeed any other troops, could long have survived such conditions as an attempt to storm works against equal numbers is not open to proof; for, while the issue was still doubtful (but the advantage naturally with the force behind the trenches), the mass of the army under the Duke of Baden came up in good time upon the right (that is, from the side of the town), poured almost unopposed over the deserted earthworks of that side, and, five to one, overwhelmed the 12,000 Franco-Bavarians upon the hill.

      After one of those short stubborn and futile attempts at resistance which such situations discover in all wars, the inevitable dissolution of d’Arco’s command came before the darkness. It was utterly routed; and we may justly presume that not 4000—more probably but 3000—rejoined the army of Marcin and of the Elector of Bavaria.

      The loss of the Schellenberg had cost Marlborough’s enemies, whose forces were already gravely inferior to his own, eight guns and
