General Kilpatrick’s division was encamped in the immediate vicinity of the town. General Buford, who was posted about two miles in advance, was attacked by the enemy about eleven o’clock in the morning. General Kilpatrick immediately moved out to the front, and, relieving the brigades of Merritt and Devin, engaged the rebels.
The Union horse artillery was planted upon a very commanding position, and was served with great effectiveness.
The enemy’s infantry pressed the National line so closely that it was compelled to fall back, though the retrograde movement was made very slowly, and the ground disputed inch by inch. The cavalry repeatedly charged the enemy, breaking his line and routing his cavalry; but the rebel infantry pressed so hard that it was at length determined to fall back upon Boonsboro’.
About night the Third division of the Eleventh corps arrived, when the Union cavalry dashed impetuously upon the enemy, and drove him three miles.
Day after day, the rebels continued to retreat, and were closely pursued by the Union soldiers; skirmishing, and occasionally sharp fighting, marked the whole line of retreat; and there was every appearance of a long, pitched battle, between the Union array and that of General Lee, before the latter could succeed in escaping with his troops across the Potomac, and back into Virginia.
At daybreak on the 10th, a fight was opened at Sharpsburg, between the Union and rebel armies, which lasted till six o’clock in the evening, and resulted in a victory to the Union arms. During the night, the town was evacuated by the rebels; Generals Lee, Longstreet, and Ewell, being the last of the rebels to leave the place. The enemy fell back toward Williamsport, and were pursued for several miles by the Federal troops.
The Army of the Potomac marched steadily on, till it was in sight of Lee’s entire army, which occupied a strong position on the heights, near a marsh, in front of Williamsport. During this, and many previous and subsequent days, there was continual skirmishing in all directions; and the great battle that now seemed imminent was most anxiously waited for by the Union forces, who were eager to be at work again.
On the morning of the 14th of July, to the unbounded astonishment of the whole of Meade’s army, it was ascertained that the rebels under General Lee had effected a most skillful retreat. Under cover of the darkness, they had withdrawn from Williamsport, and the whole force, together with all its trains, plunder, &c., had escaped across the Potomac. On the same day the Union troops occupied Williamsport and Falling Waters; capturing at the latter place, a brigade of infantry, fifteen hundred strong, two guns, two caissons, two battle flags, and a large number of small arms. A vigorous pursuit of the rebel army was immediately ordered; and on the 15th, Meade’s army pursued, overtook, and engaged the rear of the rebel army; but the enemy continued to make good his retreat, while the Unionists continued to follow closely, till on the 24th, the Union army again overtook the fugitives; and a battle on the north side of the Rappahannock appeared to be inevitable. But again the wily rebel general disappointed the brave Unionists, so eagerly awaiting an opportunity to engage and defeat his troops. During the night, General Lee again effected his escape from his pursuers, and reached Culpepper Court-House, before his movements were detected.
Active operations were now, for a time, at an end, with the Army of the Potomac. It occupied the same line on the Rappahannock, which it had held two months previous, and the wearied soldiers rested from the labors of their long and tiresome march, still wearing upon their brows the laurels they had won in General Meade’s successful if not brilliant campaign.
