“ O'Grady advanced at the head of his troops as soon as the French appeared, and presented so bold a front that, after a time, they retired. When they were out of sight he crossed the bridge at the entrance of Genappe, and took his troop at a gallop through the town, rejoining Sir William Dörnberg, who had drawn up the main body of the regiment on the sloping road at the Waterloo end of Genappe. A severe cavalry combat ensued when the French lancers reached the top of the town, in which O'Grady's regiment made a gallant charge, with considerable loss. ”
