Knowing Marlborough's destination, Tallard and Villeroi met at Landau in the Palatinate on 13 June to construct a plan to save Bavaria. 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 King Louis arrived on 27 June: Tallard was to reinforce Marsin and Maximilian II 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 Tallard; Coigny 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.
