"Before these could reach him the shock came. The First Massachusetts had the right, and fought as only brave men could to stem the tide that steadily bore them back, until the whole right gave way. Back rushed our men in wild confusion, and on came the victorious Rebel horsemen. The general saw, with anguish, his flying soldiers, yet in his extremity retained his presence of mind, and proved himself worthy the star he had won at Brandy Station. "Sending orders for the centre and left to stand fast, he placed himself at the head of the First Maine, sent to his assistance, and coolly waited till the Rebel charging columns had advanced within fifty yards of Randall's guns. He then shouted 'Forward!' and the same regiment that saved the day at Brandy Station was destined to save the day at Aldie. Rosser's men could not withstand the charge, but broke and fled up the hill. The general's horse was killed in the charge, and here the brave Colonel Doughty fell. "The general determined now to complete the victory, and, mounting a fresh horse, he urged on the First Maine and First Massachusetts, sent orders for his whole line to advance, and then sounded the charge. Lee struggled for a few minutes against this advance, and then ordered a retreat, which ended in a rout. His troops were driven in confusion as far as Middleburg, and night alone saved the remnant of his command. "This was by far the most bloody cavalry battle of the war. The Rebel chivalry had again been beaten, and Kilpatrick, who was the only general on the field, at once took a proud stand among the most famous of our Union cavalry generals. The fame of our cavalry was now much enhanced, and caused the greatest joy to the nation." _June 18._--General Pleasonton was anxious to press the Rebel cavalry back upon their infantry, to ascertain minutely their movements; hence, to-day, Kilpatrick was ordered to advance through the Bull Run Mountains, and to occupy Middleburg. Jaded as we were, as well as our horses, with the fearful yet glorious labors of the previous day, with mercury up to 98 deg. Fahrenheit in the shade, and 122 deg. in the sun, with an atmosphere unusually oppressive for Virginia, and through dust which many tramping hoofs made almost intolerable, we marched into Pleasant Valley. The outpost of the Rebel cavalry was met near the town, but they were driven from the streets, and we took possession of Middleburg. About three o'clock in the afternoon a heavy wind arose, betokening rain, which began to fall about five o'clock, mingled with hail. For this atmospheric change we had earnestly prayed. The heat had become so oppressive, and the roads so dusty, as to make our movements very unpleasant and disastrous to men and beasts, especially to the latter. In this beautiful region of country we spent a few days very pleasantly, recruiting our strength and awaiting orders. CAVALRY BATTLE AT UPPERVILLE.
