On the morning of the memorable 18th of June, the army appeared in order of battle. The Royals, Greys, and INNISKILLING dragoons, were formed on the left of the road leading from Brussels to Charleroi, to support Lieutenant-General Sir Thomas Picton's division of infantry, which crowned the heights in front of the brigade. At ten o'clock the French appeared on the opposite heights, from whence a cloud of skirmishers was sent forward; the artillery gradually opened its fire, and about noon the enemy's columns traversed the intervening space, and one of the most sanguinary, hard-contested, and important battles recorded in the annals of war commenced: a battle in which the fate of kingdoms, and the destiny of millions, was decided by British skill, and by British valour. After failing in reiterated assaults on the post of Hugomont, simultaneous attacks were formed; one of cuirassiers against the centre, which was defeated by the British household cavalry; and one of infantry against the left of the position occupied by the allied army. The formation of columns was partly concealed by the nature of the ground; but the glistening of bayonets was seen at intervals, above the undulations which form the features of this sanguinary field. Twenty thousand infantry appeared on the heights opposite the spot where the INNISKILLING dragoons were formed, and rushing forward with that eager velocity which characterizes the first attack of French soldiers, they traversed the intervening space with astonishing expedition, dispersed a Belgic brigade with which they first came in contact, broke through parts of the British supporting infantry, and ascended the position occupied by the allied army. A favourable opportunity for the Royals, Greys, and INNISKILLING dragoons to charge presented itself; the Earl of Uxbridge galloped up to the three regiments, and they instantly deployed and advanced against the dark masses of the enemy. A spirit of emulation, and a thirst for glory, beamed in the countenances of the officers and men, as they moved forward in firm array, presenting a noble spectacle of nine squadrons of superb heavy cavalry, whose warlike appearance and resolute bearing excited admiration. The French columns were urging forward with rapid steps as to certain victory; crowds of infantry and artillery fled before them; and as they ascended the crest of the position, they presented a menacing and alarming aspect. An important crisis in the battle had arrived, and stupendous results depended on the valour of the Royals, Greys, and INNISKILLING dragoons. The three regiments advanced steadily to meet these numerous and formidable bands of opponents, who were concealed from their view by the rising ground: they paused a short time to permit the retreating infantry and artillery to pass through the intervals of squadrons, and the next moment these powerful horsemen raised a loud and terrific shout, and rushed furiously upon the adverse ranks of war.
