I saw the Duke on another occasion, at a cavalry review on Hounslow Heath. The Duke of Wellington was among the spectators. He was now in military dress, and mounted on a fine chestnut-colored horse. His motions were quick, and frequently seemed to indicate impatience. Several ladies and gentlemen on horseback were admitted to the review, and within the circle of the sentries stationed to exclude the crowd. I obtained admission by paying five shillings; for I learned that in England money is quite as mighty as in America. The privileged group of fair ladies and brave men, gathered upon a grassy knoll to observe the evolutions of the soldiers, presented an assemblage such as the aristocracy of England alone can furnish. Those who imagine that this is an effeminate generation, should learn that both the men and women belonging to the British nobility, taken together, are without doubt the finest race in the world. One thing is certain, these ladies could stand fire; for although the horses leaped and pranced at the discharges of the troops, their fair riders seemed as much at ease as if upon their own feet. Their horsemanship was indeed admirable, and suggested those habits of exercise and training, to which their full rounded forms and blooming countenances gave ample testimony.
The performances consisted of various marches and counter-marches--sometimes slow, and sometimes quick--across the extended plain. The evolutions of the flying-artillery excited universal admiration. When the whole body--about four thousand horse--rushed in a furious gallop over the ground, the clash of arms, the thunder of hoofs, the universal shudder of the earth--all together created more thrilling emotions in my mind, than any other military parade I ever beheld. I have seen eighty thousand infantry in the field; but they did not impress my imagination as forcibly as these few regiments of cavalry at Hounslow Heath. One incident gave painful effect to the spectacle. As the whole body were sweeping across the field, a single trooper was pitched from his horse and fell to the ground. A hundred hoofs passed over him, and trampled him into the sod. On swept the gallant host, as heedless of their fallen companion as if only a feather had dropped from of their caps. The conflict of cavalry in real battle, must be the most fearful exhibition which the dread drama of war can furnish. On this occasion both the King and the Duke of York were present; so that it was one off universal interest. About fifty ladies on horseback rode back and forth over the field, on the flanks of the troops, imitating their evolutions.
