The French, on perceiving the arrival of the British Infantry, opened a furious cannonade from their Batteries, with a view to disturb its formation, while NEY, anxious to secure the vantage ground of a Field which he plainly foresaw, was likely to become the scene of a severe contest, renewed his attack upon Gemioncourt, still bravely defended by the 5th Dutch Militia. Hereupon, PERPONCHER, having received an Order to advance this Battalion along the high road, immediately placed himself at its head, as did also the Prince of ORANGE himself, who rode up to it at the same moment. The manner in which His Royal Highness personally led on his National Militia on this occasion, was distinguished by the most resolute and conspicuous gallantry. The Battalion was exposed to a most destructive fire from some guns which the Prince seemed determined to capture. Placing himself frequently at its head, and waving his hat, he presented in his own person so brilliant and heroic an example, that for a considerable time the Battalion maintained its ground most bravely against the far superior number of the Enemy. It was composed, however, of young and inexperienced soldiers, who had not attained sufficient confidence to fight in anything like deployed order; and, therefore, when, a few minutes afterwards, a swarm of Cavalry rushed upon it, it soon lost its compactness, and broke into a confused and hasty retreat; whilst the French Infantry succeeded in obtaining possession of the Farm, in which they firmly established themselves. The Duke of WELLINGTON, who now assumed the command, was so much alive to the importance of maintaining Gemioncourt and its inclosures, that he gave directions for its immediate occupation by a British Regiment, but the one destined for this service having by some accident been otherwise disposed of, some delay occurred, and the 28th British Regiment, commanded by Colonel Sir CHARLES PHILIP BELSON, was then marched down towards that point, under the guidance of Lieutenant Colonel GOMM, on the Staff of the Fifth Division. As the Battalion approached the Farm, the latter was discovered to be already occupied by the French, whereupon it was withdrawn to its Division.
