Among the lesser engagements of this period a spirited cavalry engagement near Aldie is worthy of note. At 3 o’clock on the 17th of June, a division of the Union cavalry encountered a rebel force, consisting of General Fitzhugh Lee’s cavalry brigade and a battery of artillery, about one mile from Aldie, on the road to Unionstown. As soon as General Lee was apprised of the approach of the National troops he made preparations to oppose their advance, and to maintain his position. The rebel Captains Boston and White, with a command of thirty men, were sent forward as sharpshooters, but not receiving any support they were compelled to fall back before the first charge of the advancing Unionists. Close behind the rebel advance the Fifth and the Third Virginia cavalry were stationed; and as the National troops charged upon them a fierce hand-to-hand encounter took place, and in the course of the fight many rebel prisoners were captured. After a brave resistance the rebels were overcome, and the order was given to fall back. Seventy-seven privates were taken prisoners, together with the following officers:—Major Carrington of the Third Virginia regiment; Captain E. B. Boston of the Fifth Virginia; Captain F. R. Winser and Captain Jones of the Third Virginia; and Captain L. B. White; Lieutenant Boston; Lieutenant Turnell; and Lieutenant Douglass of the Fifth Virginia. The loss upon the Union side was very trifling; the men fought with the greatest bravery. It was dark before the fight was finally at an end, light artillery firing being kept up on both sides, without any material injury to either; and when night fell it saw the Union troops entirely victorious, and the rebels slowly retiring.
