But WELLINGTON, foreseeing the probability of a serious attempt upon this weakened point of his Line, and perceiving the approach of CHASSÉ's Division (see page 458), supplied the required remedy by desiring Lord HILL to bring forward troops from the Second Line. The zeal, intelligence, and activity which had ever characterized the Hero of Almaraz and Arroyo del Molino when carrying out the designs of the Chief under whom he had acquired a lasting fame, seemed but to wait this summons to the more immediate scene of action, to appear again in all their accustomed vigour. He immediately put in motion DU PLAT's Infantry Brigade of the King's German Legion. As the latter advanced across the Nivelles road, from its left, the 2nd Line Battalion became the leading Column. It was followed by the 4th, then by the 3rd, and lastly by the 1st Line Battalion. As the 2nd approached the crest of the ridge, several Gunners ran in upon it for shelter from the Enemy's _Cuirassiers_, whose main body was now advancing against this Battalion. The four Light Companies of the Brigade, however, had just posted themselves close to the three small trees near this part of the crest of the ridge; and being armed with rifles, they delivered so destructive a fire into the Cavalry as to compel it to withdraw. Some of the Allied Cavalry then moved forward in pursuit, and DU PLAT's Brigade continued its advance until the 2nd Line Battalion had approached close to the hedge of the Great Orchard of Hougomont, whence a dropping fire was opened upon the Germans by the French Skirmishers. The Dragoons made a sudden and rapid retreat through the intervals of the Columns, in left front of which a fresh Line of hostile Cavalry now presented itself. Captain SYMPHER, who, with his Horse Battery of the Legion, had accompanied DU PLAT's advance, instantly unlimbered; and poured round shot through the intervals of the Columns, the latter maintaining, at the same time, a very effective independent file fire. The _Cuirassiers_ gallantly advanced, notwithstanding this formidable resistance. They first became exposed to a flank fire from the left face of the 4th Line Battalion Square, and then again to that from the left face of the 3rd Line Battalion: nevertheless, they resolutely attacked the Battery, the Gunners of which either flew to the last mentioned Square for protection, or sought shelter under the carriages. At length, after having suffered severe losses by the unremitting fire from the nearest Squares, the French Cavalry retired in disorder; receiving a renewed discharge from the Battery, which was again in full play.
