His plans were now manifest enough, but it was too late to catch him. He therefore halted two days by Ladenburg to give orders for the concentration of the troops that were on march to join him from the Rhine, and then striking south-eastward across the great bend of the Neckar, traversed the river for the second time at Lauffen, and by the 10th of June was at Mondelheim. Halting here for three days to allow his infantry to come nearer to him, he was joined by Prince Eugene whom he now met for the first time in the flesh. The Prince inspected the English horse and was astonished at the condition of the troops after their long and trying march. "I have heard much," he said, "of the English cavalry, and find it to be the best appointed and finest that I have ever seen. The spirit which I see in the looks of your men is an earnest of victory." Hither three days later came also a less welcome guest, Prince Lewis of Baden; and the three commanders discussed their plans for the future. Marlborough in vain tried to keep Eugene for his colleague, but it was ultimately decided that Eugene should take command in the lines of Stollhofen, to prevent the French if possible from crossing the Rhine, and to follow them at all hazards if they should succeed in crossing, while Baden should remain on the Danube and share the command of the allied army by alternate days with Marlborough.

Then the march was resumed south-eastward upon Ulm; and after one day's halt to perfect the arrangements for the junction with Prince Louis, the army reached the mountain-chain that bounded the valley of the Danube. The Pass of Geislingen, through which its road lay, could not in the most favourable circumstances be passed by any considerable number of troops in less than a day, and was now rendered almost impracticable by incessant heavy rain. To add to Marlborough's troubles the States-General, learning that Villeroy was astir, became frightened for their own safety and entreated for the return of their auxiliary troops. The Duke, to calm them, ordered boats to be ready to convey forces down the Rhine, and went quietly on with his own preparations, establishing magazines to the north of the Danube, and not forgetting to send a reinforcement of foreign troops to Eugene. At last the news came that Baden's army was come within reach; the British cavalry plunged into the defile, and two days later the junction of the two forces was effected at Ursprung.

The joint armies presently advanced to within eight miles of Ulm, whereupon the Elector of Bavaria withdrew to an entrenched camp further down the Danube between Lavingen and Dillingen. The Allies therefore turned northward to await the arrival of the British infantry at Gingen; for Charles Churchill, with the foot and the artillery, had found it difficult to march at great speed in the perpetual pouring rain. His troubles had begun from the moment when Marlborough had gone ahead with the cavalry from Coblentz. The ascent of a single hill in that mountainous country often cost the artillery[303] a whole day's work, and would have cost more but for the indefatigable exertions of the officers.[304] Marlborough's care for the comfort and discipline of these troops was incessant. A large supply of shoes, for instance, was ready at Heidelberg to make good defects, while constant injunctions in his letters to his brother testify to his anxiety that nothing should be omitted to lighten the burden of the march. Finally, anticipating Wellington in the Peninsula, he insisted that the men should pay honestly for everything that they took, and took care to provide money to enable them to do so. Such a thing had never been known in all the innumerable campaigns of Germany.

The joint armies after the arrival of Churchill amounted to ninety-six battalions, two hundred and two squadrons, and forty-eight guns; but a large contingent of Danish cavalry was still wanting, and not all Marlborough's entreaties could prevail with its commander, the Duke of Würtemberg, to hasten his march. Nevertheless it was necessary to move at once. Marlborough's objective had from the first been Donauwörth, which would give him at once a bridge over the Danube and a place of arms for the invasion of Bavaria. His move northward had revealed his intentions; and the Elector of Bavaria had detached Count d'Arco with ten thousand foot and twenty-five hundred horse to occupy the Schellenberg, a commanding height which covers Donauwörth on the north bank of the Danube. Marlborough pressed Baden hard to attack this detachment before it could be reinforced; and accordingly the army broke up from Gingen, and advancing parallel to the Danube encamped on the 1st of July at Amerdingen.

The next day was Marlborough's turn for command. It had not yet dawned when Quartermaster-General Cadogan was up and away with a party of cavalry, pioneers, and pontoons. At three o'clock marched six thousand men from the forty-five battalions of the left wing,[305] three regiments of Imperial Grenadiers, and thirty-five squadrons of horse. At five o'clock the rest of the army, excepting the artillery, followed in two columns along the main road towards a height that overhangs the river Wörnitz between Obermorgen and Wörnitzstein. By eight o'clock Cadogan was at Obermorgen, had driven back the enemy's picquets, and was engaged in marking out a camp; and at nine appeared the Duke himself, who, taking Cadogan's escort, went forward to reconnoitre the position.

The Schellenberg, as its name implies, is a bell-shaped hill, some two miles in circumference at the base and with a flat top about half a mile wide, whereon was pitched the enemy's camp. On the south side, where the hill falls down to the Danube, the ascent is steeper than elsewhere; on the north-west the slope is gradual and about five hundred yards in length. To the south-west the hill joins the town of Donauwörth, from the outworks of which an entrenchment had been carried for nearly two miles round the summit to the river. This defence was strongest and most complete to the north-east, where a wood gave shelter for the formation of an attacking force; and at this point was stationed a battery of cannon. To the north-west the works though incomplete were well advanced, and were strengthened by an old fort wherein the enemy had mounted guns. Marlborough, as he conned the position, could see that the enemy before him was so disposed as if expecting an attack on the northern and western sides. But looking to his right beyond Donauwörth, and across the Danube, he could see preparations of a more ominous kind, a camp with tents pitched on both wings and a blank space in the centre, sure sign that cavalry was already present and that infantry was expected. Closer and closer he drew to the hill, Prince Lewis and others presently joining him; and then puffs of white smoke began to shoot out from various points in the enemy's works as his batteries opened fire.
