In the same month followed the engagements of Middleburg and Upperville, in each of which the "Harris Light" participated with great eclat, charging in face of the enemy's guns, forming in platoon under fire, and routing him in splendid style. At Upperville, Kilpatrick received orders to charge the town. With drawn sabres and shouts which made the mountains and plains resound, they rushed upon the foe. The encounter was terrific. The enemy's horse were driven through the village of Paris, and finally through Ashby's Gap upon their own infantry columns in the Shenandoah Valley. At Rector's Cross-Roads, where Kilpatrick ordered the "Harris Light" to charge the enemy's battery, as they were forming, a fatal bullet pierced Glazier's horse, and it fell dead under him. Fortunately he was not dragged down in the fall, and as he struck the ground a riderless horse belonging to an Indiana company came up. Its owner, a sergeant, had been shot dead, and, rapidly mounting, Lieutenant Glazier rode forward with his regiment as they valiantly charged the enemy's position. These actions were succeeded by the battle of Gettysburg (July first, second and third), in which the disasters of Chancelorsville and Fredericksburg were fully retrieved, and the rebel army, under Lee, received a blow so staggering in its effects as to result in a loss of prestige, and all hope in the ultimate success of their cause. Prior to this battle the Confederates had warred upon the North aggressively; thenceforward they were compelled to act upon the defensive. During the progress of this great and (so far as the ultimate fate of the Confederacy was concerned) decisive battle, the cavalry, including the brigade to which our subject was attached, performed brilliant service. They held Stuart's force effectually at bay, and while the retreat of the rebel army was in progress their services were in constant requisition. On the first day of the battle, General John Buford, commanding the Third Cavalry Division, was in position on the Chambersburg Pike, about two miles west of the village. Early in the forenoon the vanguard of the rebel army appeared in front of them, and our dauntless troopers charged the enemy vigorously, and drove them back upon their reserves. The second day of the battle was spent by the cavalry in hard, bold and bloody work, in collision with their old antagonists, Stuart, Lee and Hampton. Charge succeeded charge; the carbine, pistol and sabre were used by turns; the artillery thundering long after the infantry around Gettysburg had sunk to rest exhausted with the carnage of the weary day. Stuart, however, was driven back on his supports, and badly beaten.
