The campaign of 1691 happily typifies the relative positions of the combatants in almost every respect. The French concentrated ten thousand men on the Lys. This was sufficient to paralyse all the garrisons of the Allies on and about the river. They posted another corps on the Moselle, which threatened the territory of Cleves. Now Cleves was the property of the Elector of Brandenburg, and it was not to be expected that he should allow his contingent of troops to join King William at the general rendezvous at Brussels, and suffer the French to play havoc among his possessions. Thus the Prussian contingent likewise was paralysed. So while William was still ordering his troops to concentrate at Brussels, Boufflers, who had been making preparations all the winter, suddenly marched up from Maubeuge and, before William was aware that he was in motion, had besieged Mons. The fortress presently surrendered after a feeble resistance, and the line of the Allies' frontier between the Scheldt and Sambre was broken. William moved down from Brussels across the Sambre in the hope of recovering the lost town, outmanœuvred Luxemburg, who was opposed to him, and for three days held the recapture of Mons in the hollow of his hand. He wasted those three days in an aimless halt; Luxemburg recovered himself by an extraordinary march; and William, finding that there was no alternative before him but to retire to Brussels and remain inactive, handed over the command to an incompetent officer and returned to England. Luxemburg then closed the campaign by a brilliant action of cavalry, which scattered the horse of the Allies to the four winds. As no British troops except the Life Guards were present, and as they at any rate did not disgrace themselves, it is unnecessary to say more of the combat of Leuse. It, had however, one remarkable effect: it increased William's dread of the French cavalry, already morbidly strong, to such a pitch as to lead him subsequently to a disastrous military blunder. The campaign of 1691 was therefore decidedly unfavourable to the Allies, but there was ground for hope that all might be set right in 1692. The Treasurer, Godolphin, was nervously apprehensive that Parliament might be unwilling to vote money for an English army in Flanders; but the Commons cheerfully voted a total of sixty-six thousand men, British and foreign; which, after deduction of garrisons for the safety of the British Isles, left forty thousand free to cross the German Ocean.
