The first is the march of Marlborough and Baden upon Donauworth and the capture of that city, which was the gate of Bavaria.
The second is the consequent invasion and ravaging of Bavaria, the weakening of the Elector, and his proposal to capitulate; the consequent precipitate advance of Tallard to the aid of the Elector, and the corresponding secret march of Eugene to help Marlborough.
The third occupies the last few days only: it is concerned with the manoeuvres immediately preceding the battle, and especially with the junction of Marlborough and Eugene, which made the victory possible.
THE FIRST PHASE
_From the junction of Marlborough and Baden to the fall of Donauworth_
When the Duke of Marlborough had joined hands with the forces of Baden upon the 22nd of June 1704 his general plan was clear: the last of his infantry, under his brother Churchill, would at once effect their junction with the rest at Ursprung, and he and Baden had but to go forward.
His great march had been completely successful. He had eluded and confused his enemy. He was safe on the Danube watershed, and within a march of the river itself. The only enemies before him on this side of the hills were greatly inferior in number to his own and his ally"s. His determination to carry the war into Bavaria could at once be carried into effect.
With this junction the first chapter in that large piece of strategy which may be called "the campaign of Blenheim" comes to an end.
Between the successful termination of his first effort, which was accomplished when he joined forces with Baden upon the Danube side of the watershed in the village of Ursprung, and the great battle by which Marlborough is chiefly remembered, there elapsed, I say, seven summer weeks. These seven weeks are divided into the three parts just distinguished.
In order to understand the strategy of each part of those seven weeks, we must first clearly grasp the field.
The accompanying map shows the elements of the situation.
East of the Black Forest lay open that upper valley of the Danube and its tributaries which was so difficult of access from the valley of the Rhine.
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.
[Ill.u.s.tration: Map ill.u.s.trating the march of Marlborough and Baden across Marcin"s front from the neighbourhood of Ulm to Donauworth.]
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 a.s.sumed.
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 Donauworth, and their direct march upon Donauworth 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, pa.s.sed 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 Donauworth (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 Donauworth 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, Donauworth 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_ Donauworth 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 (princ.i.p.ally at Nordlingen), and the pa.s.sing 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 pa.s.sage over this was therefore also of high importance to the Duke of Marlborough and his allies. Now, a man holding Donauworth can cross both rivers at the same time unmolested, for they meet in its neighbourhood.
Further, Donauworth 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.
[Ill.u.s.tration: Map showing how Donauworth is the key of Bavaria from the North-West.]
No serious permanent defences, such as could delay the capture of the town, surrounded Donauworth; but up above it lies a hill, called from its shape "the Sch.e.l.lenberg" 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 Donauworth, 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 Sch.e.l.lenberg was master of Donauworth 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 Sch.e.l.lenberg. 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 a.s.sault 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 ma.s.s 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 Sch.e.l.lenberg had cost Marlborough"s enemies, whose forces were already gravely inferior to his own, eight guns and close upon one-fifth of their effective numbers. The Franco-Bavarians hurried south to entrench themselves under Augsburg, while Donauworth, and with it the pa.s.sage of the two great rivers and the entry into Bavaria, lay in the possession of Marlborough and his ally.
The balance of military and historical opinion will decide that Marlborough played for too high stakes in beginning the a.s.sault so late in the evening and with so small a force. But he was playing for speed, and he won the hazard.
It was a further reward of his daring that he could point after this first engagement to the fine quality of his British contingent.[6]
It was upon the evening of July the 2nd, then, that this capital position was stormed. It was upon the 5th that Marcin and the Elector lay hopeless and immobile before Augsburg, while their enemies entered a now defenceless Bavaria by its north-western gate. And this complete achievement of Marlborough"s plan was but the end of the first phase in the campaign upon the Danube.
Meanwhile, a large French reinforcement under Tallard was already far up on its way from the Rhine, across the Black Forest, to join Marcin and the Elector of Bavaria and set back the tide of war, and, when it should have effected its junction with those who awaited it at Augsburg, to oppose to Marlborough and the Duke of Baden a total force greater than their own.
The French marshal, Tallard, was in command of the army thus rapidly approaching in relief of the Franco-Bavarians. His arrival, if he came without loss, disease, or mishap, promised a complete superiority over the English and their allies, unless, indeed, by some accident or stroke of genius, reinforcement should reach _them_ also before the day of the battle.
This reinforcement, in the event, Marlborough _did_ receive. He owed it, as we shall see, to the high talents of Prince Eugene; and it is upon the successful march of this general, his junction with Marlborough, and the consequent success of Blenheim, that the rest of the campaign turns.
We turn next, then, to follow the second phase of the seven weeks, which consists in Tallard"s advance to join the Elector, and in Eugene"s rapid parallel march, which brought him, just in time, to Marlborough"s aid.
THE SECOND PHASE
_The Advance of Tallard_
To follow the second phase of the seven weeks, that is, the phase subsequent to the capture of the Sch.e.l.lenberg and the retirement of Marcin and the Elector of Bavaria on to Augsburg, it is necessary to hark back a little, and to trace from its origin that advance of Tallard"s reinforcements which was to find on the field of Blenheim so disastrous a termination.
We shall see that in this second phase Tallard did indeed manage to effect his junction with the Elector and Marcin with singular despatch; that this junction compelled Marlborough and Baden to cease the ravaging of Bavaria upon which they had been engaged, and to join in closely watching the movement of the Franco-Bavarian forces, lest their own retreat or their line of supplies should be cut off by that now large army.
The Sch.e.l.lenberg was stormed, as we have seen, on the 2nd of July.
