with a 3-year enlistment period. The regiment originally consisted of 10 companies, band and regimental staff. The regiment followed the standard structure of the three-year volunteer regiments of ten companies of 83-101 men (which could be split into two battalions on an ad hoc basis) and a field staff of 36-66. The officers were divided into field staff who ran the regiment and battalions and the line or company officers who ran the companies. Due to a lack of personnel and infrastructure ready when the war began, the federal government left the recruiting, equipping, and providing of recruits to the states with reimbursement to come from the federal level upon muster into federal service. Since the states were handling the process, existing militia companies building to full-strength followed the existing militia practice of voting in new recruits which made recruitment slower than the new volunteer companies in the regiment. Five companies reached the rendezvous early in July, 1861, by direction of the governor when the defeat at Bull Run shook Washington, DC. In response, on July 22, Lincoln authorized the call-up of 500,000 more three-year enlistments. The debacle spurred the The next day, the Secretary of War issued a call for all available regiments and detachments to be hurried forward at once. Up to the 20th of August three more companies had formed. Most of the line officers were mustered on that day, and the enlisted men in camp were sworn in four days later. As a consequence, the regiment mustered into federal service on August 27, 1861 with only eight companies. Orders to report with the command at Washington were then received, and the journey began on the August 28th, with a full complement of officers, and eight hundred and ninety-one men. About a month later Company A joined the regiment, but Company C did not re port for duty till the last of November, being sworn into the United states service January 14, 1862.


1861

Going by way of New York, Harrisburg, and Baltimore, the Eighteenth reached Washington 30 August, and next day reported to Colonel E.D. Baker, going into camp about a mile to the west of the Capitol, the location being called Camp Massachusetts. The regiment was ordered on the 3d of September to cross the river and report to General Fitz John Porter, commanding a division, by whom it was assigned to General Martindale's Brigade, its fellow regiments being the Second Maine, Thirteenth and Forty-first New York. The regimental camp was located near Fort Corcoran, on ground recently occupied by the Sixty-ninth New York, and the Eighteenth began to see actual service in fatigue duty and on picket. The division was moved to the front on the 26th and went into camp near Hall's Hill, then the outpost of the Union army. This position was occupied during the winter, the regiment giving much attention to drill and discipline, so that at a review held at Bailey's Cross Roads it was especially complimented for excellence by the commander in chief, and as a mark of appreciation received new uniform and camp equipage imported from France and modeled on that of the French chasseurs a pied. Before the opening of the spring campaign some changes were made in Martindale's Brigade, the Forty-first New York giving place to the Twenty-second Massachusetts and Twenty-fifth New York Regiments, while the Second Company of Massachusetts Sharpshooters was attached to the brigade, which was known as the First Brigade, Porter's Division, Third (Heintelman's) Corps.


1862

The winter camp was vacated 10 March 1862, and the regiment marched to Fairfax, stopping there until the 16th, when it was ordered to Alexandria to embark for the Peninsula. Transports were taken on the 21st, and two days later the command debarked at Old Point Comfort, encamping at Hampton for two days and then at Newmarket Bridge, where it remained until the Federal army was ready for the forward movement. This began on 4 April, and early on the afternoon of the following day the defenses of Yorktown were reached, before which the Army of the Potomac came to a halt and remained for a month. The Eighteenth took active part in the earlier operations by which the enemy's line was located, and three of its companies were at once placed on the skirmish line, while the remainder of the regiment formed a portion of the main line of battle, but no casualties were suffered. Later the command went into camp near by and daily furnished heavy details for outpost and fatigue duty until the evacuation of Yorktown. Immediately on that event Porter's Division took transports and landed on 8 May at West Point, near the junction of the Mattaponi and Pamunkey rivers. Up the south side of the latter the division marched, setting out on the 13th, going first to Cumberland, thence to White House, moving on the 19th toward Richmond as far as Tunstall's Station, and on the 26th to Gaines Mills. During this time the Fifth (Provisional) Army Corps had been formed, of which General Porter was given command. It was composed of his own division, the command of which was taken by General Morrell, and another under General Sykes. The brigade to which the Eighteenth belonged was strengthened by the addition of the First Michigan Regiment, and was known as the First Brigade, First Division. About the same time the regiment exchanged the smooth-bore muskets with which it had thus far been armed for the Springfield rifled pattern. Early in the morning of the 27th the division set out for Hanover Court House, but as the Eighteenth had been on picket during a heavy storm it was not in condition to march at once; and though it followed a few hours later it was not in time to take part in the brilliant action by which General Porter defeated the Confederate force under General Branch. It assisted in burying the dead left upon the field by the enemy and on the 29th returned to its camp at Gaines Mills. There it remained until 26 June, when with the Seventeenth New York of Butterfield's Brigade it was detached from the division to accompany a force of cavalry and artillery under General Stoneman for the protection of the army supplies at White House. The operations which followed were arduous, and demanded many of the best qualities of soldiership, but all were performed in a manner to win praise. The stores there having been destroyed in conformity with McClellan's purpose to change base to the James river, the regiment embarked on transports, dropped down the river and finally by way of Fortress Monroe arrived at Harrison's Landing, where it debarked for one day before the arrival of the rest of the brigade, which meantime had been fighting its way across the Peninsula. With the rest of the army, the Eighteenth encamped at Harrison's Landing until 15 August, the only movement of note during that time so far as they were concerned being a reconnaissance to the Chickahominy the last of July, returning to camp the same day. Before the transfer to the vicinity of Washington, however, various changes occurred among the officers. Colonel Barnes took command of the brigade, succeeding General Martindale, who was made military governor of Washington; Lieutenant Colonel Ingraham had been made colonel of a new Massachusetts regiment, then being recruited; Major Hayes having been prostrated by sickness was necessarily away from the regiment, and the command devolved upon Captain Thomas, under whom the march was made on the 15th to the Chickahominy, thence by way of Williamsburg, Yorktown, and Hampton to Newport News, where on the 20th transports were taken for Acquia Creek. Going from there by rail to Falmouth, the regiment marched to Rappahannock Station, where it arrived on the 23d. The next few days were devoted to maneuvering and marchings to and fro, falling back on the 27th to Warrenton, next day to Catlett's, and on the 29th to Manassas Gap. From this point it marched to the battle of Manassas, or the Second Bull Run, in which it was destined to take an important part. As the brigade, temporarily under the command of Colonel Charles W. Roberts of the Second Maine, came upon the field during the forenoon of the 30th it was formed in double line of battle with supports in echelon, the Eighteenth forming the first line in rear of the skirmishers, two of its companies being deployed to extend the skirmish line so as to form connection on the right. An attempt was then made to advance across a field and through a piece of woods, by which it was hoped to flank a Confederate battery; but the failure of troops to the right and left to advance rendered the attempt futile; the brigade was soon obliged to half and answer the fire which was poured in from front and both flanks, and after half an hour of this unequal contest the decimated regiments fell back to a less exposed position, Syke's Division (Second) of the same corps covering their withdrawal. That night the regiment, which had won high praise for its gallantry during the day, retired with its corps to Centerville. It had lost in the engagement 40 killed, 101 wounded and 28 missing – more than half the number taken into action. Of the dead were Captain Charles W. Carroll, First Lieutenant Warren D. Russell and Second Lieutenant Pardon Almy Jr. Previous to this two officers of the regiment had died from disease – First Lieutenant George F. Hodges on 31 January and Second Lieutenant John D. Isbell on 16 July. Major Hayes returned to the command of the Eighteenth on 1 September. He was soon promoted to the vacant lieutenant colonelcy, Captain Thomas being made major; the commissions dated from 25 August, but it was some time later that the recipients were mustered to the new rank. During the night of the 1st and the following day the regiment marched to Chain Bridge, going on the 3d to Hall's Hill, where it rested until evening of the 6th. It then moved by night to Alexandria and staid until the 9th, thence to Fort Corcoran, opposite Georgetown, making another three-day's halt. Then began the march to the Antietam, where the Fifth Corps arrived on the 16th, but beyond supporting batteries on the east side of the creek the Eighteenth took no active part in the engagement. After the fighting was over the regiment was detailed for picket near the Burnside bridge, at the left, where it passed the 18th and the succeeding night, advancing the next day to the Potomac. It crossed that river on the 20th, leading its brigade, and opened the action of Shepherdstown, in which the two brigades commanded by Barnes and Sykes encountered four times their number of Confederates, and being unsupported were obliged to fall back. The Eighteenth retired in good order, having lost three killed, 11 wounded and one missing. Following this unsatisfactory experience, the regiment remained in camp near Sharpsburg for about six weeks. The movement southward began on 30 October, when the column marched toward Harper's Ferry, crossed the Potomac there the following day and advanced by easy stages to Warrenton, where it went into camp on the 9th. During this time the brigade, still commanded by Colonel Barnes, had been enlarged by the addition of the One Hundred and Eighteenth Pennsylvania Regiment; the division was at that time under General Charles Griffin and the corps was commanded by General Butterfield. Camp was broken on the 17th, the regiment moving by way of Elktown to Hartwood Church, encamping there from the 19th to the 23d and then advancing to a position on the railroad near the village of Falmouth. It remained there, with the exception of a reconnaissance back to Hartwood Church on 1 December, until the 11th of that month, when it took position further down the river, opposite Fredericksburg, and remained in waiting there until the afternoon of the 13th before it was called on to join in that battle. The call to action came at 1 o’clock, when the regiment led its division across the river, being the first of the Fifth Corps to cross. The brigade at once went to the front and relieved a brigade of the Ninth Corps which had suffered severely in an attempt to reach the enemy's line of works. A charge was made soon after by the Eighteenth, but it was not successful and cost the command heavily in killed and wounded. After falling back it was reformed and again took its place in the front of the Union line where it remained during the rest of the afternoon and in that vicinity until the evening of the next day, when it retired to the town and early the next morning as part of the rear guard covered the withdrawal of the troops from that side of the river. The loss of the regiment in this battle was 13 killed and 121 wounded among the former being Captain George C. Ruby and Second Lieutenant James B. Hancock of Cambridge, and of the nine officers wounded Captain Joseph W. Collingwood would die on the 24th. Every member of the color guard was wounded, so severe was the fire upon the colors; but not a member of the regiment was missing from his place save the killed and wounded when the ordeal was over.
