context_page_description: The Battle of Blenheim, fought on 13 August 1704, was a major battle of the War of the Spanish Succession. The overwhelming Allied victory ensured the safety of Vienna from the Franco-Bavarian army, thus preventing the collapse of the reconstituted Grand Alliance.
  Louis XIV of France sought to knock the Holy Roman Emperor, Leopold out of the war by seizing Vienna, the Habsburg capital, and gain a favourable peace settlement. The dangers to Vienna were considerable: the Elector of Bavaria and Marshal Marsin's forces in Bavaria threatened from the west, and Marshal Vendôme's large army in northern Italy posed a serious danger with a potential offensive through the Brenner Pass. Vienna was also under pressure from Rákóczi's Hungarian revolt from its eastern approaches. Realising the danger, the Duke of Marlborough resolved to alleviate the peril to Vienna by marching his forces south from Bedburg to help maintain Emperor Leopold within the Grand Alliance.
context_section_description: On 10 June, the Duke met for the first time the President of the Imperial War Council, Prince Eugene – accompanied by Count Wratislaw – at the village of Mundelsheim, halfway between the Danube and the Rhine. By 13 June, the Imperial Field Commander, Prince Louis of Baden, had joined them in Großheppach. The three generals commanded a force of nearly 110,000 men. At conference it was decided that Eugene would return with 28,000 men to the Lines of Stollhofen on the Rhine to keep an eye on Villeroi and Tallard and prevent them going to the aid of the Franco-Bavarian army on the Danube. Meanwhile, Marlborough's and Baden's forces would combine, totalling 80,000 men, for the march on the Danube to seek out the Elector and Marsin before they could be reinforced.
  Knowing Marlborough's destination, Tallard and Villeroi met at Landau in the Palatinate on 13 June to rapidly construct a plan to save Bavaria but the rigidity of the French command system was such that any variations from the original plan had to be sanctioned by Versailles. The Count of Mérode-Westerloo, commander of the Flemish troops in Tallard's army wrote – "One thing is certain: we delayed our march from Alsace for far too long and quite inexplicably." Approval from Louis arrived on 27 June: Tallard was to reinforce Marsin and the Elector on the Danube via the Black Forest, with 40 battalions and 50 squadrons; Villeroi was to pin down the Allies defending the Lines of Stollhofen, or, if the Allies should move all their forces to the Danube, he was to join with Marshal Tallard; and General de Coignies with 8,000 men, would protect Alsace. On 1 July Tallard's army of 35,000 re-crossed the Rhine at Kehl and began its march.
  On 22 June, Marlborough's forces linked up with Baden's Imperial forces at Launsheim. A distance of 400 kilometres (250 miles) had been covered in five weeks. Thanks to a carefully planned time-table, the effects of wear and tear had been kept to a minimum. Captain Parker described the march discipline – "As we marched through the country of our Allies, commissars were appointed to furnish us with all manner of necessaries for man and horse ... the soldiers had nothing to do but pitch their tents, boil kettles and lie down to rest." In response to Marlborough's manoeuvres, the Elector and Marsin, conscious of their numerical disadvantage with only 40,000 men, moved their forces to the entrenched camp at Dillingen on the north bank of the Danube. Marlborough could not attack Dillingen because of a lack of siege guns – he was unable to bring any from the Low Countries, and Baden had failed to supply any despite assurances to the contrary.
  The Allies, nevertheless, needed a base for provisions and a good river crossing. On 2 July, therefore, Marlborough at the Battle of Schellenberg stormed the fortress of Schellenberg on the heights above the town of Donauwörth. Count Jean d'Arco had been sent with 12,000 men from the Franco-Bavarian camp to hold the town and grassy hill but after a ferocious and bloody battle, inflicting enormous casualties on both sides, Schellenberg finally succumbed, forcing Donauwörth to surrender shortly afterwards. The Elector, knowing his position at Dillingen was now not tenable, took up a position behind the strong fortifications of Augsburg.
  Tallard's march presented a dilemma for Eugene. If the Allies were not to be outnumbered on the Danube, Eugene realised he must either try to cut Tallard off before he could get there or he must hasten to reinforce Marlborough. if he withdrew from the Rhine to the Danube, Villeroi might also make a move south to link up with the Elector and Marsin. Eugene compromised: leaving 12,000 troops behind guarding the Lines of Stollhofen, he marched off with the rest of his army to forestall Tallard.
  Lacking in numbers, Eugene could not seriously disrupt Tallard's march but the French Marshal's progress was proving pitifully slow. Tallard's force had suffered considerably more than Marlborough's troops on their march – many of his cavalry horses were suffering from glanders and the mountai
