As the Prussians passed us, (for I had the honour and good fortune to be an actor in this scene,) I heard their bands play, “God save the King!” which soul-stirring compliment we returned by hearty cheers. In the pursuit of the enemy from Rossomme to Genappe, the Prussian lance and sabre were busy in the work of death. Many a brave soldier, that had escaped the bloody field, fell that night beneath the deadly steel. In vain did the French make a feeble effort to check the Prussians at Genappe, by barricading its long and narrow street with their remaining guns and tumbrels. So entirely had their defeat destroyed their discipline, that the Prussians, by the first sound of the trumpet, beat of drum, or their wild hurrah, overcame every obstacle, and, pressing on, they captured sixty pieces of cannon. The Duke, after clearing the high-road and its left of the allied troops, in order to give full scope to the advancing Prussians, to whom he relinquished the further pursuit of the flying enemy, remained for some time with his advanced troops on the right of Rossomme in conversation with general Vivian, colonel Colborne and others; after which, promising to send the provisions up, his Grace turned his horse round and rode away. On returning leisurely towards Waterloo, about ten o’clock, at a short distance before reaching La Belle-Alliance, he, aided by a clouded moon, descried a group of mounted officers making towards the Genappe high-road from the direction of Frischermont; the Duke turned off to meet them: it proved to be Blücher and his staff; they most heartily congratulated each other on the glorious result of the contest in which they had been so intensely engaged. The conference lasted about ten minutes, when the veteran Blücher, promising to leave his inveterate foe no rallying time on this side of the frontier, shook hands with his Grace and proceeded to Genappe, sending forward to general Gneisenau, who led his advance-guard, orders to press and harass the enemy, and not suffer the grass to grow under their feet, or even allow them to take breath. Bulow’s corps, which led the pursuit, was supported by Zieten’s. Pirch’s corps received orders to turn round and strike across the country, and, if possible, to cut off marshal Grouchy’s retreat.
