ThePennsylvania Reserves were aninfantrydivision in theUnion Army during theAmerican Civil War. Noted for its famous commanders and high casualties, it served in theEastern Theater, and fought in many important battles, includingAntietam andGettysburg.
WhenPresidentAbraham Lincoln called for volunteers to "put down the rebellion" in the spring of 1861, the commonwealth ofPennsylvania found itself with more volunteers than needed to meet its Federal quota. Although 14 regiments were requested, Pennsylvania exceeded this by providing 25 organized regiments.[1] TheSecretary of War,Simon Cameron, was a political enemy ofAndrew Curtin,Pennsylvania governor, and refused to take the extra men into Federal service. Curtin decided to retain the extra men and organized, trained, and equipped them at state expense. The creation of the special division was approved by the Pennsylvania legislature on May 15, 1861, "for the purpose of suppressing insurrections, or to repel invasions."[2] The men were trained at camps of instruction in four cities:Easton,Pittsburgh,West Chester, andHarrisburg. The training camp near Harrisburg was namedCamp Curtin for the governor.
Fifteen regiments were formed, known as the 1st through 15th Pennsylvania Reserves (they were later designated the 30th through 44th Pennsylvania Volunteers, but generally retained the label of the Pennsylvania Reserves). At the time of the redesignation, Pennsylvania had other troops both in the field or in various stages of development using the same numbers. While many of these units used their designations into middle and late 1862, much confusion arose over the naming convention. Additional naming confusion occurred within the ranks of the reserves. The13th Pennsylvania Reserve Regiment (42nd Pennsylvania Volunteers) was additionally named the 1st Pennsylvania Rifles. Although better known as the "Bucktails," this regiment became officially known as the First Rifles. The same can be said regarding the 14th and 15th Pennsylvania Reserves (43rd and 44th Pennsylvania Volunteers), which officially were designated as the 1st Pennsylvania Light Artillery and the 1st Pennsylvania Cavalry, respectively.
The regiments were grouped into a division of threebrigades, and the entire unit normally fought together until the initial enlistments expired in 1864. The exceptions to this include the 2nd Brigade, most of which did not take part atGettysburg, as it was assigned to theWashington, D.C., defenses,[3] and the detachment of several artillery batteries and cavalry troops to other divisions.
The first commander wasGeorge A. McCall, and later division commanders wereJohn F. Reynolds,George G. Meade, andSamuel W. Crawford.Truman Seymour twice was acting commander, once on the Peninsula and once at Antietam, when Meade became acting commander ofI Corps. The initial brigade commanders were Reynolds, Meade, and Colonel John S. McCalmont (untilEdward Otho Cresap Ord took official command of the 3rd Brigade).

Initially assigned toI Corps, in June 1862, the division was transferred to theVirginia Peninsula where it served with theV Corps of theArmy of the Potomac during thePeninsula Campaign. The division then returned to its old corps (which was at the time designatedIII Corps in theArmy of Virginia) during theSecond Bull Run Campaign. The division's parent formation resumed its I Corps designation just prior to the Antietam campaign when it rejoined the Army of the Potomac. The division participated in the battles ofSouth Mountain,Antietam, andFredericksburg, particularly distinguishing itself at Fredericksburg, where it penetrated the Confederate lines. Between Fredericksburg and Gettysburg, the division was a part of theXXII Corps assigned to Washington, D.C. It was part of the V Corps again for the Battle of Gettysburg, where it distinguished itself on July 2, 1863, fighting aroundLittle Round Top. One brigade drove Confederate forces from the western slopes of Little Round Top back to the Wheatfield. Under Crawford, the Pennsylvania Reserves continued to fight with the Army of the Potomac until just before the Battle of the Bethesda Church orBattle of Totopotomoy Creek, when the men's three-year enlistments expired.
A large number of the men re-enlisted and became the190th and191st Volunteer Infantry regiments and fought until the end of the war.
