Near Upperville, Virginia, Union cavalry again clashes with the Confederate cavalry screen
In one of several attempts to penetrate the Confederate cavalry screen shielding the Army of Northern Virginia's advance into Pennsylvania, Union cavalry under General Alfred Pleasanton clashed with General J.E. B. Stuart's men near Upperville, Virginia. In furious and close fighting, the screen again held but every fight delayed Stuart and his vital task of serving as the "eyes and ears" of his commander.
