The INNISKILLING dragoons reposed in cantonments among the Belgic peasantry about six weeks; being stimulated by the fame acquired by several corps in the Peninsular campaigns, from 1808 to 1814, they were eager for an opportunity to signalize their intrepidity and prowess against the enemies of their country, and this opportunity was soon afforded them. About four o'clock on the morning of the 16th of June, they were suddenly aroused by the notes of the bugle summoning them to assemble, mounted, at the alarm posts. Springing from their beds with alacrity, they were speedily equipped, and, as the Belgic husbandmen commenced their labours in the field, the INNISKILLING dragoons were seen directing their march towards _Quatre Bras_, where the French divisions, under Marshal Ney, had suddenly attacked the advance-posts, while Bonaparte assailed the Prussians at Ligny with the main body of his army. Continuing its route by Enghien, Brain-le-Conte, and Nivelles, the regiment arrived at the scene of conflict a little before midnight; the hostile forces were reposing on their arms; and the SIXTH bivouacked behind the position, in a corn-field on the left of the road from Charleroi to Brussels. The Prussians having retreated, the Duke of Wellington made a corresponding movement, and the INNISKILLING dragoons were employed in covering the retreat of the infantry and artillery to the position of Mont St. Jean, in front of the village of _Waterloo_. On passing through Genappe, a heavy thunder-storm deluged the country and put a stop to the firing; but as the atmosphere cleared, the scene became particularly interesting; the cavalry brigades were manœuvring in the face of the adverse army; the loud tones of the artillery, the fire of skirmishers in the fields, the seventh hussars and first life guards charging the French lancers in the streets, while Bonaparte urged forward his numerous squadrons, thinking to overwhelm the British horsemen, presented to the eye an animating and splendid spectacle. On arriving at the heights of Mont St. Jean, an opposition was presented to the French emperor, which he despaired to overcome that evening, and the hostile forces confronted each other during the night, the men and horses being exposed to a continual rain.
