On Saturday, 8th of June, orders came for an expedition to Harper's Ferry. The day before starting, we had issued to us new caps of the French forage pattern, also white linen havelocks, to wear over them, which added greatly to the appearance of the men, being likewise a decided protection from the scorching rays of the June sun.

June 10th, the regiment broke camp, and marching to Washington took cars for Baltimore, arriving at which place we marched across the city to embark for Chambersburg, Pennsylvania. We had anticipated trouble in marching through the streets of Baltimore; but the roughs of the then rebellious city knew better than to oppose the passage of a regiment and battery armed and equipped as was the 1st Rhode Island. The regiment marched across the city from the depot where we landed, without a halt, with its band playing national airs. We were well supplied with ammunition, and the battery could have swept the streets of any mob essaying to obstruct its progress. We soon reached and boarded the cars, arriving at Chambersburg at noon, 11th, and starting again by rail for Greencastle, Pennsylvania, which place we reached at sunset the same day. After leaving the train we marched about three miles beyond the town, where we bivouacked for the night in a grove beside the road. We had no tents nor rations, the wagons not having come up. The regiment formed in a hollow square, stacked their muskets, and lay down on the ground, without covering, other than their blankets; sentinels were posted on the road, the battery parked in the rear of the regiment, and every precaution taken against surprise during the night. Tents arrived the next morning at daylight, but no rations. The tents we pitched and made preparations for a few days' stay. Troops were all the time coming and marching. The army to which we were at that time attached, comprised about nine thousand men, commanded by General Patterson, and was organizing for an attack upon Harper's Ferry.

June 12th, at noon, Governor Sprague rejoined us, having left Rhode Island at once on learning that we had departed from Washington.

At about sunset, while many of the regiment were seated on fences watching the passing troops, a Pennsylvania regiment came along the road, halting a few moments for rest in front of our camp. Directly some of our regiment discovered a man in one of the Pennsylvania companies who had been arrested by our regiment as a spy, while we were quartered at the Patent office in Washington. A rush was made for him, he was dragged from his company, and but for the intervention of some of our officers he would have been strung up on the spot.

Saturday morning, June 13th, we once more started, our destination being Williamsport, Maryland, distant fourteen miles. This was one of the hardest marches that we made. The weather was hot, the roads rough and dusty, and when we went into camp at Williamsport, there was only one officer and fourteen men of our company with the colors, present. The balance of the company were exhausted, and were straggling along the road, but by sunset they had all arrived in camp. We pitched our tents in the woods and rested the whole of Sunday.

Monday morning, June 15th, broke camp at daylight, and started on the road for Harper's Ferry. We had barely got started, when a mounted orderly arrived from Hagerstown, Maryland, with orders for Colonel Burnside to return with his regiment and battery to Washington, at once. Harper's Ferry had been evacuated by the rebels, who were also moving in the direction of Washington. Our regiment and battery set out at once on the road for Hagerstown, arriving there at noon. Without stopping we marched on through Funkstown, arriving at Boonsboro, Maryland, at 3 P. M., where we halted for a rest. We found the people of the place loyal, and disposed to show us every possible attention. We halted on the public square, or common, and the ladies of the town gathered in large numbers and supplied many of us with cake and other refreshments. Here the regiment and battery rested until 5 P. M., when the march was resumed. Entering a pass of the South Mountain, the acclivity looming up on both sides, every precaution was taken against any possible surprise by the enemy. The battery was divided, one-half in the advance and the remainder in the rear of the column.

At 9 P. M. we reached Middletown, where the people showed themselves in large numbers, as we passed their quiet homes. We made no stop at Middletown, but tramped along, tired and hungry, stopping about midnight and camping on a hill on the outskirts of Frederick City, Maryland, having marched thirty-six miles since daylight. Men from all the companies soon collected rails and built a camp-fire, illuminating the surrounding country and causing the ringing of a fire alarm in Frederick City.

At 4 A. M. June 18th, we broke camp and marched into Frederick, halting at some old barracks, said to have been built during the Revolutionary war. We were the first Union troops that had entered Frederick City since the commencement of hostilities, and the event naturally caused no little stir among the inhabitants of that semi-rebellious city. Nearly if not quite all its prominent citizens were in sympathy with the rebel cause, and we were consequently not regarded by them with any degree of favor. The presence, however, of twelve hundred well drilled and disciplined troops and a battery of six rifled guns, proved a quite potent reminder of what might be expected should there be any undue interference. Soon after entering Frederick, our company was marched to a restaurant and provided with an excellent breakfast, after which we returned to the old barracks. We were given permission by our officers to look about the city, with orders to report in camp at noon. Many of the citizens were found to be true Union men, by whom we were courteously received and kindly treated, and I don't believe that during our brief stay in town any member of the regiment, either by word or deed, left any unfavorable impression among the inhabitants. In the afternoon, just previous to the departure of the regiment, a deputation of Union citizens, both men and women, waited upon us and presented to Mrs. Kady Brownell an elegant American flag. Mrs. Brownell was the wife of Robert S. Brownell, of Company H, and when her husband enlisted, in Providence, she insisted on accompanying him, and was with the regiment during its entire term of service, in all its long marches sharing its privations and enduring its hardships. At the battle of Bull Run she was on the skirmish line with her husband, who was at the time a sergeant. She wore a uniform somewhat similar to that of the regiment, and was proficient in the use of a revolver and a short, straight sword, that she always wore suspended at her side.

At about 4 P. M., the regiment took up the line of march for the depot, to take cars for Washington. In marching through one of the principal streets leading to the depot, a crowd of rebel toughs issued from a side street, and following us, volunteered insulting remarks concerning us and the flag. Captain Tew, of our company, had at that time a colored servant, who had been with us for some time. This sooty individual, who was known by the name of John, had somewhere on the march picked up an antiquated sword and belt, which he had buckled on and felt very proud of. The sight of this negro, thus attired, appeared to kindle the wrath of Frederick City's chivalry to such an extent that they attempted to seize and make way with the boy, and for a short time the excitement ran high. The color sergeant, seeing that an attack upon us was threatened, drew his revolver and stood on the defensive. The right wing of the regiment, not being aware of the disturbance, continued on its march. Lieutenant Colonel Pitman, who was in command of the left wing, noticing the aspect of things, took prompt action, halting the companies, most of the men of F company loading their muskets, as they expected that the mob, which by this time had largely increased in numbers, would make an attack. At this juncture Colonel Burnside rode up and was about to issue some order to our officers, when a squad of city police, or home guard, appeared upon the scene and dispersed the mob, after which we resumed our march, soon arriving at the depot, where we took a train for Washington, reaching that place at daylight the next morning, June 19th.
