THREE MONTHS' SERVICE. 107
ton, private Maguire, of company H, was killed by the accidental discharge of
a musket in the hands of a comrade.
At the end of three weeks, the regiment was relieved by the First Delaware
volunteers? Colonel Lockwood, and was ordered to concentrate at Havre-deGrace. Tents were funished, and the men were supplied with overcoats, belts,
and cartridge-boxes, which to this time had been wanting. On the 18th of
June, orders were received to march, via Baltimore and Harrisburg, to Chambersburg, and join General Patterson's column. It was rumored at Havre-deGrace, that it would be attacked in its passage through Baltimore, but no demonstration was made. Remaining a few days at Chambersburg, it was ordered
to Hagerstown, Maryland, where it was attached to General Negley's Brigade
of General Keim's Division. By careful drill and instruction, and the devoted
attention of its officers, the regiment had been brought to as good a state of
discipline as could be expected of men to whom the camp was new, and who
had been but a few weeks under military pupilage. On the night of June 18th,
the long roll was beaten, and being quickly in column, it was hurriedly marched
to Williamsport, where an attack was apprehended; but, as a large force was
concentrated by daylight, the enemy deemed it prudent to retire, and late in
the day it marched back to the camp at Hagerstown.
On the 20th of June; the regiment was transferred to the 6th Brigade,* to
the command of which Colonel (since General) J. J. Abercrombie, of the Seventh U. S. infantry, was assigned. On the 28th of June, it moved to Downstown, where a detachment, under Lieutenant Colonel Coulter, was ordered to
proceed to the Potomac, in the neighborhood of dam No. 4, and select a suitable
ford for the passage of the army. After a fruitless night's labor Colonel Coulter reported that no safe fording, with the present stage of water, could be
found. On the following day the regiment moved to Williamsport, where the
army had principally concentrated, and where preparations were made for
crossing the river. At two o'clock on the morning of the 2d of July, a scouting party, consisting of one hundred and fifty men of the Eleventh, and Captain M'Mullen's company of Rangers, the whole under command of Lieutenant
Colonel Coulter, forded the river and pushed forward into the enemy's country.
Colonel Abercrombie, with the remainder of his Brigade, advanced to its support, followed by the whole army. As the head of the column approached the
ford, firing was heard on the Virginia side, Coulter's detachment having come
in contact with a body of rebel scouts, who were quickly put to flight.
Abercrombie, having crossed, immediately put his Brigade in motion, and
proceeded about two miles in the direction of Hoke's Run, better known as
Falling Waters, when day began to dawn, and the detachment rejoined the
Brigade. It was reported that a strong force of the rebel army was posted at
Falling Waters. Advancing to within a mile of this point, being several hours
in advance of the main column, the Brigade halted, and a detachment was
again sent forward to reconnoitre; but no enemy was encountered. On arriving
at the stream, the troops refreshed themselves, and filled their canteens. The
march was resumed; but before proceeding far the enemy was discovered,
posted in a wood. The Eleventh immediately formed on the right of the road,
