On the morning after our arrival here, we heard the sounds of cannonading not far off, and learned that the cavalry under General Pleasanton were hotly engaged at Aldee and Upperville, with Stuart's rebel cavalry, and that our forces were getting the best of the desperate encounter, winning laurels for themselves and gaining another of that series of victories which was destined to remove the derision in which that arm of the service had been held, not from any previous want of good fighting qualities on the part of our cavalry. General Pleasanton had attacked Stuart's forces near Middleburgh, driving the rebels in confusion through Upperville to Ashby's Gap, taking some pieces of artillery and a large number of prisoners. General Kilpatrick, in this engagement, had exhibited fighting qualities of the first order, riding in front of the men and leading the way when they hesitated. His gallant conduct inspired for him the confidence and admiration of his men. It was the commencement of a brilliant career which made him one of the first cavalry commanders in the army. His dashing ride from the Peninsula to Fredericksburgh, with but a handful of men, eluding the watchfulness of the wily Stuart, had already established his talent for bold adventure, and his conduct on this occasion proved his personal bravery. These are the two great qualities needed for a cavalry officer, and Kilpatrick's name at once became a tower of strength among his men.

In this pleasant locality the corps remained, an outpost for the army, guarding the passes from the Shenandoah, for five days. The weather was delightful, and the men enjoyed, to the utmost, the needed rest. They lounged in the shade of their tents or in the neighboring groves, or strolled along the railroad track, examining curiously the ruined remains of the trains. In a delightful spot at a distance from the camps, almost surrounded by a grove of oak trees, the hospital tents of our Second division were erected. To this quiet and lovely spot, where cool breezes always played, were brought the sick and weary, and carefully nursed.

But General Lee despaired of inducing General Hooker to uncover the capital, so, leaving Virginia with his whole army, he pushed toward Pennsylvania, determined at least to draw our army as far away from Washington as possible, and to reap rich harvests of spoils among the overflowing granaries of the Keystone State. No sooner had the movement of the main body of Lee's army into Maryland commenced, than General Hooker, with his forces, commenced the pursuit.

CHAPTER XIX.

THE GETTYSBURGH CAMPAIGN.

The rebels in Pennsylvania—Panic at Harrisburgh—Alarm at Baltimore and Washington—Sixth corps leaves Bristow Station—A surprise—General Meade takes command—Position of the army—Marching through Pennsylvania—An unprecedented march—Exciting news—Battle of Gettysburgh—Death of Reynolds—First and Eleventh corps fall back—Second day's battle—The battle-field—Fighting at Round Top—On the right—The grand onset—The battle decided—Rebel and Union wounded.

Meanwhile, great excitement prevailed at the north, especially in Maryland and Pennsylvania, on account of the invasion of the rebel army. As early as the 15th of the month, more than a thousand rebel cavalry had reached Chambersburgh, which they had sacked. Two days before, the battle of Winchester was closed. Ewell, with overwhelming numbers had fallen upon General Milroy's force, which had unwisely been, by order of somebody, thrust far away from its base, and out of the reach of reinforcements, routing the division, and in its flight capturing its artillery and a large portion of the infantry.

Nothing now opposed the march of the invaders through the Shenandoah Valley. In Harrisburgh, the excitement rose almost to a panic. All the paintings, books, papers, and other valuable articles, were removed from the capitol, packed in boxes and loaded into cars, ready to be sent off at the first sign of immediate danger. The citizens formed themselves into military companies, and worked day and night throwing up redoubts and rifle pits about the city. Men unaccustomed to manual labor vigorously plied the pick and the spade, and kept up their unwonted toil with an earnestness worthy of veteran soldiers. To add to this confusion and alarm, the trains of Milroy's division that had escaped capture were rattling through the streets in search of a resting place. Throughout the State of Pennsylvania business was suspended. The governor was calling loudly for men to rush to arms in defense of their homes; and General Couch was striving to organize the militia which presented itself.

Baltimore and Washington were like besieged cities. Stuart was threatening the Baltimore and Ohio road, and bodies of rebel cavalry had penetrated within half a dozen miles of Washington. Bells rung out the alarm, and the affrighted citizens rushed to arms. Loyal leagues were now of service, forming the nucleus of many an improvised company of defenders. All these facts we learned from the newspapers, a few stray copies of which fell within the path of the army, and from the highly colored accounts of citizens, who, with expressions of the utmost alarm and anxiety, related what they had heard or seen.

On the night of the 26th of June, the Sixth corps left Bristow Station. The darkness was intense, and a drizzling rain rendered marching disagreeable. The march was rapid, and some of the men fell behind, and were next day collected and marched off to Richmond, by the guerilla parties that constantly hung upon our flanks and rear. Before daylight we halted at Centreville. The men threw themselves upon the wet ground, and slept for two hours, while the rain beat upon them. Then, at six o'clock, they were again roused, by the order to be ready to move at once. While taking our coffee, and waiting for the final order to march, some villain, belonging to the troops stationed at Centreville, set fire to the little Episcopal chapel that stood not far from us, and was the only building remaining in the little village which pretended to any appearance of modern architecture. Those vandals who follow an army, bent on nothing but destruction, are among the unavoidable evils of war, and even the most severe discipline is insufficient to effectually arrest all mischief of the kind.
