Montfrault, however, had fared ill in his attempt to withdraw. Until he reached the ground between Wattrelos and Roubaix, his square preserved good order; but being attacked at that point by overpowering numbers from the south as well as from north and west, it was broken up, and fled in disorder towards Leers. Meanwhile General Fox, finding himself absolutely isolated, at length gave the order for his brigade, which so far had held its own, to retire. The retreat began in perfect order, and the brigade, having successfully fought its way to the road at Lannoy, followed it for some distance, under incessant fire from all sides, until checked by a battery covered by an abatis, which the French had thrown up on the road. The first shots from this battery struck down several men, and Fox for the moment feared that surrender would be inevitable; but fortunately in the ranks of the Fourteenth was a French emigrant who knew the district well, and undertook to lead the brigade across country. It pursued its retreat therefore under constant fire of artillery and musketry in front and on both flanks, and with cavalry constantly threatening its rear; but it kept its assailants at bay, and at one moment made so sharp a counter-attack as to take temporary possession of some French guns. Thus partly by good luck, partly by good conduct, partly by the misconduct and mismanagement of the enemy, the three battalions contrived to reach Leers, with the loss of all their battalion-guns excepting one, and of nine officers and five hundred and twenty-five men out of eleven hundred and twenty. The greatest credit was given to General Fox for the coolness, skill, and patience with which he extricated his brigade.
