HALKETT's Brigade, with the Brunswickers, resolutely maintained the ground on which they had been charged by the French Cavalry. As the latter retired, the Light Companies of the Brigade, with a portion of the Brunswickers on the right, and some Hanoverian Riflemen on the left, advanced in pursuit. The French threw forward a line of _Tirailleurs_ to check them, and a brisk fire was maintained on both sides. The cannonade on this side of the field was also kept up with great spirit. At length the French Cavalry advanced, forcing back HALKETT's Skirmishers upon their respective Columns, on which they then charged. Their attack, however, was not made with much energy, and, upon their being uniformly repulsed, the Light Troops resumed their former ground. HALKETT pushed forward his Battalions to the line of his Skirmishers, and then moving towards his right, in the direction of the ravine, which descends from the Wood, drove across the rivulet a body of French Infantry, from which a portion of his Brigade had suffered a severe fire. In this part of the affair one of PICTON's Battalions--the Royals--co-operated. The two Brunswick Battalions continued boldly to advance even beyond this line, resting their right close upon the Wood. * * * * * In the meantime, BYNG's Brigade had closely followed up MAITLAND's in support, having previously sent forward its Light Companies under Lieutenant Colonel MACDONELL round by Quatre Bras, skirting the eastern border of the Wood. The spirited and determined nature of the advance of the British Guards not admitting of that restraint which, considering the many intricate parts of the Wood, was essential for the preservation of order, led to great confusion in their ranks by the time they reached the southern extremity, after having fairly driven out the French; and in this state they ventured to pursue the Enemy on the open ground, but were quickly repulsed by his Reserves; and the French Artillery poured so destructive a fire into this portion of the Wood, that MAITLAND deemed it advisable to withdraw the 2nd Battalion (under Colonel ASKEW) to the rivulet, where it was immediately joined from the rear by the other Battalion of his Brigade (the 3rd, under Colonel the Hon. WILLIAM STUART).
