Meanwhile the Union Brigade on the left, consisting of the Royals and the Inniskillings, with the Scots Greys in support, had broken into the fight. The Royals, coming on at full speed over the crest of the ridge, broke upon the astonished vision of the French infantry at a distance of less than a hundred yards. It was an alarming vision of waving swords, crested helmets, fierce red nostrils, and galloping hoofs. The leading files tried to turn, but in an instant the Royals were upon them, cutting them down furiously. De Lacy Evans, who rode in the charge, says, "They fled like a flock of sheep." Colonel Clark Kennedy adds that the "jamb" in the French was so thick that the men could not bring down their arms or level a musket, and the Dragoons rode in the intervals between their formation, reaching forward with the stroke of their long swords, and slaying at will. More than 2000 Frenchmen flung down their arms and surrendered; and on the next morning the abandoned muskets were still lying in long straight lines and regular order, showing that the men had surrendered before their lines were broken. The charge of the Inniskillings to the left of the Royals was just as furious and just as successful. They broke on the front of Donzdot's divisions and simply ground them to powder. The Scots Greys were supposed to be "in support"; but coming swiftly up, they suddenly saw on their left shoulder Marcognet's divisions, the extreme right of the French. At that sight the Greys swung a little off to their left, swept through the intervals of the 92nd, and smote the French battalions full in front. As the Greys rode through the intervals of the footmen--Scotch horsemen through Scotch infantry--the Scotch blood in both regiments naturally took fire. Greetings in broadest Doric flew from man to man. The pipes skirled fiercely. "Scotland for ever!" went up in a stormy shout from the kilted lines. The Greys, riding fast, sometimes jostled, or even struck down, some of the 92nd; and Armour, the rough-rider of the Greys, has told how the Highlanders shouted, "I didna think ye wad hae saired me sae!" Many of the Highlanders caught hold of the stirrups of the Greys and raced forward with them--Scotsmen calling to Scotsmen--into the ranks of the French. The 92nd, in fact, according to the testimony of their own officers, "went half mad." What could resist such a charge?
