overhung the Norken and was occupied by the village of Oycke, was unguarded by the French. He caused Overkirk with the Dutch reserve to march round the hills to occupy this point, and thus completely envelop the French right. The effect was the total annihilation of that part of the French army, and it was owing to an accident alone that any part of it escaped. The two extremes of the enveloping English line came so close together, that in the darkness they fired upon each other. The mistake was happily soon discovered, but fearing a repetition of the accident, the general gave orders rather to let the French escape than to run the risk of renewing such a disaster. Some 9000 men thus broke through at a gap in the semicircle of hills near the Castle of Bevere, and made their escape to France. The rest of the beaten army retired toward Ghent. [Illustration: Battle of Oudenard. July 11th, 1708.] [Sidenote: Siege of Lille. Dec. 9, 1708.] Both armies were speedily reinforced. Eugene's troops arrived from the Moselle, and joined the English; Berwick, with part of the army of the Rhine, which had been observing them, reinforced the French, but the relative numbers of the troops were not much changed. Marlborough and Eugene had now to settle upon a further plan of action. Before them lay the great city of Lille, one of the earliest conquests of Louis XIV., newly fortified with all the skill of Vauban. That the allies should cross the frontier and enter France was speedily determined. But while Marlborough suggested the bold plan of leaving troops to mask Lille, while the main army marched direct to Paris, Eugene, though by no means a timid general, urged the more regular course of besieging and capturing the great fortress which lay in their way before proceeding further. The arguments in favour of this plan were too plausible to be disregarded. It was decided that while Eugene in person undertook the siege, Marlborough should command the covering army. Even to bring the siege material to the spot was a matter of no small difficulty; the artillery alone required 16,000 horses, and the progress of the siege was watched by a French army of 100,000. When these preliminary difficulties were triumphantly overcome, there still remained the great fortress itself, occupied by 15,000 men, under the able command of Boufflers. At one time the Dutch deputies were so alarmed at the slowness of the progress made that they urged the renunciation of the project. One of the greatest difficulties experienced by the allied commanders was the provisioning of the army; the land communication with Brussels was entirely cut off, all provisions had to be brought from Ostend, whither they had been conveyed by sea. The French determined to interrupt this line of communication also, and to destroy one of the convoys which had been intrusted to General Webb, with a most insufficient detachment of troops. It has been suggested that
