The 48th Pennsylvania Infantry was recruited in Schuylkill County, Pennsylvania and organized at Camp Curtin in Harrisburg, Pennsylvania, during August and September 1861. It was mustered into federal service there, by detachments, in mid-September. Many members of the regiment had seen prior service in at least three Pennsylvania units which had seen service as 'three-month term of enlistment' organizations - the 6th, 14th, and 25th Pennsylvania Infantry regiments. A large number of men in the regiment had been miners prior to the war.[1]
Initially equipped with smoothbore muskets which had been converted from flintlock to percussion, the regiment was then re-equipped with Enfield rifles in May 1862.
On September 17, 1862, at Antietam, the 48th Pennsylvania's brigade assisted in carrying Burnside's Bridge, and crossed it soon after 1:00 PM. After the repulse of three divisions later in the day, two brigades advanced to the crest of the ridge to check Confederate pursuit. The 48th Pennsylvania supported and relieved the 51st Pennsylvania, engaging the Confederates posted on the line and behind the stone walls right and left of that point. The engagement continued into the night, and the regiment and brigade bivouacked on the ground on which they had fought.[1]
Following Antietam, the 48th Pennsylvania camped at Pleasant Valley, Maryland, until October 27. The unit moved to Falmouth, Virginia, October 27 – November 17, and on to Corbin's Cross Roads near Amissville on November 10. The Battle of Fredericksburg followed from December 12 to 15, and then an aborted campaign on January 20–24, 1863, known as the Mud March.[2]

The 48th Pennsylvania then played an integral role in what would become known as the Battle of the Crater on July 30, 1864. In mid-1864, Grant wanted to defeat Lee's army at Petersburg without resorting to a lengthy siege—his experience in the Siege of Vicksburg told him that such affairs were expensive and difficult on the morale of his men. Lieutenant Colonel Henry Pleasants, commanding the 48th Pennsylvania Infantry of Major General Ambrose Burnside's IX Corps, offered a novel proposal to solve Grant's problem. Pleasants, a mining engineer from Pennsylvania in civilian life, proposed digging a long mine shaft underneath the Confederate lines and planting explosive charges directly underneath a fort (Elliott's Salient) in the middle of the Confederate First Corps line. If successful, Union troops could drive through the resulting gap in the line into the Confederate rear area. Digging began in late June, creating a mine in a "T" shape with an approach shaft 511 feet (156m) long. At its end, a perpendicular gallery of 75 feet (23m) extended in both directions. The gallery was filled with 8,000 pounds of gunpowder, buried 20 feet (6.1m) underneath the Confederate works.[4]
Result of the explosion
At 4:44a.m. on July 30, the charges exploded in a massive shower of earth, men, and guns. A crater (still visible today) was created, 170 feet (52m) long, 60 to 80 feet (24m) wide, and 30 feet (9.1m) deep. The blast destroyed the Confederate fortifications in the immediate vicinity, and instantly killed between 250 and 350 Confederate soldiers.
The 48th Pennsylvania participated in several further battles of the Petersburg campaign in 1864: Globe Tavern (August 18–21), Peebles's Farm (September 29–October 2), and Boydton Plank Road (October 27–28).[2] At the Third Battle of Petersburg on April 2, 1865, regimental Surgeon William R. D. Blackwood removed wounded comrades from the battlefield under heavy fire, for which he was later awarded the Medal of Honor.[5] After occupying the city of Petersburg, the unit marched to Farmville, Virginia, on April 3–9. The 48th Pennsylvania returned to the Petersburg and City Point area on April 20–24, then moved on to Alexandria, Virginia, on April 26–28.[2]
Following the end of the war, the regiment took part in the Grand Review of the Armies in Washington, D.C., on May 23. The unit served at Washington and Alexandria until being mustered out on July 17, 1865.[2] A monument was erected by the Commonwealth of Pennsylvania in Branch Avenue, Antietam Battlefield, MD to commemorate the services of the 48th Regiment, Pennsylvania Veteran volunteers and it was dedicated on September 17, 1904. Survivors of the 48th Regiment attended the dedication. Another monument was built and paid for by the 48th Regiment Pennsylvania Veteran Association and given to the state of Virginia. The monument was dedicated on June 20, 1907, in Richmond, Virginia.[Story of the Forty-Eighth by Joseph Gould]
