Service

This regiment was organized at Philadelphia and mustered into federal service on April 29, 1861.[1] This regiment was the outgrowth of a rifle battalion attached to the 1st brigade, 1st division of the Pennsylvania militia.

On May 20 it was ordered to Suffolk Park; on the 28th to Chambersburg, where it became part of Patterson's army. It crossed the Potomac on June 17, but the force soon returned to the Maryland side and encamped. On July 2 the army moved to Martinsburg and thence after a fortnight, to Bunker Hill, Charlestown, and Harper's Ferry. While in Martinsburg the 21st was presented with a beautiful flag by the loyal Union Germans of that city. On August 9, the 21st boarded trains in Martinsburg, and returned to Philadelphia, via Harpers Ferry and Baltimore. The regiment mustered out at Philadelphia that day.[2][3][4]

  1. ^ An 1840 graduate of West Point and roommate of William T. Sherman, Thomas, a Virginia native remained loyal during the war, would achieve fame as one of the principal commanders in the Western Theater.
  2. ^ The 69-year old Patterson was a Cappagh, County Tyrone, Ireland born United States soldier. The son of a rebel during the 1798 Rebellion who was banished from the United Kingdom, had emigrated to Philadelphia in 1799 with his family.[5] He volunteered for service during the War of 1812, he rose from the rank of captain to colonel in the Pennsylvania Militia, before joining the United States Army. He was discharged in 1815 as a captain. Patterson returned to commercial pursuits in manufacturing and mills, getting involved in Pennsylvania politics. He had a busy commercial and political career but interrupted it again to serve in the Mexican-American War as a major general of volunteers. He saw action during the Siege of Veracruz and at the Battle of Cerro Gordo, where he was wounded. Mustering out, he returned to Philadelphia and resumed his business career becoming quite wealthy. The American Civil War brought Patterson back to military service. He was appointed major general of Pennsylvania volunteers and commanded the Department of Pennsylvania and the Army of the Shenandoah. In 1861, Winfield Scott, now General-in-Chief of the U.S. Army, gave Patterson vague orders to retake Harpers Ferry. Despite inflicting an early defeat on Stonewall Jackson at the Battle of Hoke's Run, he is remembered mostly for crucially failing to stop Confederate General Joseph E. Johnston from joining forces with P. G. T. Beauregard at the First Battle of Bull Run. Although still blamed for this defeat, Brig. Gen. Joseph E. Johnston, however, admit that Patterson's army had largely deterred him from pursuing the U. S. troops in retreat following the battle.[6] Patterson mustered out of the Army in late July 1861.[5]
