It was intended that the regiment should march for Washington by the direct country road, a distance of about thirty miles; and much of the time next day was spent in scouring the neighborhood for horses, mules, and wagons, to serve as ambulances and for transporting the baggage and camp equipage. But in the afternoon dispatches were received from Washington, directing the troops to come, if possible, by the Annapolis branch of the Baltimore and Washington railroad, in order that this important line of communication might be kept open for future use. This was a single-track road, running twenty miles northwest from Annapolis to its junction with the Baltimore and Washington line. The depot at Annapolis was closed and abandoned by the company, and the track had been disabled for some distance out of town. When General Butler, with two companies of the Eighth Massachusetts, broke open the depot, he found there a few passenger and platform cars, with only one locomotive; and that had been taken to pieces and rendered unserviceable. But the Massachusetts regiment was largely composed of mechanics, who were not only good workmen but enterprising and quick-witted. By a singular chance one of them recognized, among the fragments of the engine, a piece of machinery which he had himself helped to make; and he lost no time, with the aid of his comrades, in putting together again the disjointed limbs of the locomotive, and making it in a few hours once more fit for work. Others repaired the railroad track in the neighborhood, and before dawn on the 24th everything was ready for two companies of the Seventh to move forward as advance guard on the line of march.

Soon after daylight the whole regiment was in motion. The locomotive and a couple of platform cars were in front, carrying a howitzer with its caisson; and one or two passenger and baggage cars served to carry baggage and camp equipage, and to provide for the transportation of sick or wounded. The railroad embankment, which was our only route, ran through a narrow clearing in the woods, with low hills and swampy lands alternating on either side. The day was still and warm, and a few of the men were prostrated by the unaccustomed exertion and heat. About noon we came up with the advance guard, and from that point, after a short halt, all moved on together. Missing rails and broken culverts were a constant impediment to our advance; and toward evening we came to a deep and wide watercourse, where the long trestle bridge had been burned a day or two before. But these obstacles only seemed to stimulate the volunteers. Heretofore their annoyances and disappointments had been from causes beyond their control. Now that every difficulty was within reach, they went at it with a will, and thought of nothing but how to overcome it. The ruined bridge hardly delayed them three hours. The engineer officer and his men went into the woods on each side, where a hundred busy hands were soon at work, felling trees and hauling them into place; and before dark, the stream was spanned by a new bridge of rough-hewn timbers that carried the train over safely, and our march began again.

So it went on all through the night. The missing rails had often been thrown, for better concealment, into some deep pool or watercourse near by. But after a little experience, that was the very first place where they were sought for and generally found. If the search proved ineffectual, it made little difference at last; for at every siding the extra rails were taken up and carried forward on the train, to be used as they might be needed further on. So the track was made serviceable for ourselves, and left in good condition for those who were to follow. There was a line of skirmishers in front and one on each flank, to beat up the enemy, should he be there lying in wait. Once or twice a few marauders were sighted, tearing up the rails or reconnoitering our advance; but they all retreated promptly, without firing a shot or waiting for the head of the column, and none of them were even seen by the main body. That was all. The desperate resistance we were expected to meet with from swarming rebels and armed guerrillas turned out to be a sham. When the advance guard about daylight occupied the village of Annapolis Junction, there was no opposition. The regiment took possession of a deserted station, and the railroad communication with Washington at last was ours.

It is remarkable how greatly the presence of an armed force conduces to friendly feeling on the part of the inhabitants. No doubt the secessionists hereabout had done their best for a few days past to prevent our ever arriving at Annapolis Junction. But now that we were there, and especially in need of a freshly cooked breakfast, there was little difficulty in obtaining one for the officers' mess. The fatigue and drowsiness that had been almost overpowering during the night, gave way like magic before the refreshing stimulus of the dawn; and the keen morning air awakened an appetite that demanded something better than pork and hardbread from the haversack. Among the neighboring farmhouses there were some quite ready to supply our wants.

Early in the forenoon a train made its appearance from the direction of Washington. It had been sent out to meet us, under guard of a detachment of National Rifles, a volunteer company of the District of Columbia; and we were soon on board and under way. The cars were crowded to the utmost; but we were now nearing our destination, and every discomfort seemed a trifle. For some distance this side of Washington the road was picketed; and before long we began to see at intervals the head and shoulders of a National Rifleman, with his fresh looking uniform and glittering bayonet, peering at us over the bushes as the train went by. Finally, about noon, the city came in sight. It was Thursday, the 25th. We had been six days in getting from New York to Washington. They had been days of doubt and anxiety, of hindrances, delays, and stoppages. Every hour was precious, and yet we knew that with all possible dispatch we might still be too late. And even now, at the outskirts of the city, we could hardly help looking to see whether the flag of the nation still floated over the Capitol. The train rolled into the depot, the regiment disembarked, formed in column, marched to the White House, reported to the President, and our journey to Washington was accomplished.

There was no doubt about the sense of relief created by our arrival. After nearly a week of isolation and peril, Washington breathed more freely. The only troops there before us were the Sixth Massachusetts, a handful of regulars, and about thirty volunteer companies of the District of Columbia, mainly recent recruits. The Seventh was a full regiment, well disciplined and thoroughly equipped. What was of still more consequence, it had opened the door of Annapolis and reëstablished communication with the north. The Eighth Massachusetts arrived next day from Annapolis Junction; and within another week one more regiment from Massachusetts and four from New York followed by the same route. After that, the city of Baltimore ceased to be an obstruction, and the trains came through from Philadelphia as usual. By the middle of May there were nearly twenty-five thousand troops gathered for the defense of Washington.

For the first week after our arrival we were quartered in the Capitol building; but at the end of that time the regiment went into camp a mile or so north of the city, on Meridian Hill. This was a plateau of about forty acres, admirably adapted for the purpose. It was on the direct road to Harper's Ferry, where the rebels were in possession, and would give security against incursions from that quarter. The camp was on the east side of the road, where there was a fine suburban estate, with a large, square-built mansion house and outbuildings. From the road entrance a well graded avenue led up to the house porch, which stretched its hospitable covering over the carriage way. The house was occupied by regimental headquarters and the staff officers. In front were green fields and orchards, falling away in a gentle slope toward the city; and beyond was the broad Potomac, with the Virginia shore and Arlington Heights in the distance. In the rear were the lines of company tents, and an ample parade-ground, where the regiment was reviewed every day or two by the President, the Secretary of War, the general commanding, or some other high civil or military official, who was usually as much an object of inspection to the troops as the troops were to him.

By degrees other camps began to spring up round about us. On the opposite side of the road were three regiments of New Jersey volunteers, under General Runyon. A field in front of us was the daily exercise ground of a mounted battery of the regular army; and farther down, on the left, was the Twelfth regiment of New York volunteers. The Eleventh New York, under Colonel Ellsworth, was in camp below the city beyond the navy yard. This regiment was affiliated with our own through its second officer, Lieutenant-Colonel Farnham, who had been until then a lieutenant in the Seventh, and had commanded the skirmish line in the march from Annapolis.

The time was coming when the regiment would have something else to do than drilling and camp duty. Washington was saved from the danger that menaced it at the outset; and so long as the troops were there, it was secure from a sudden inroad. But it had no permanent defenses. The Potomac River was the limit of its territory. On the opposite shore the rising ground of Arlington Heights commanded all approaches from that direction; and every day, with a good spyglass, we could see the fluttering of a secession flag in the little city of Alexandria, only six or seven miles away. This was a precarious situation for the seat of government and centre of military operations; and no one was surprised when it made an attempt to burst its shackles.
