Overview
The 72nd Pennsylvania Infantry (Three Years’ Service), also known as the “Fire Zouave” regiment, was an infantry unit raised in Philadelphia, Pennsylvania, for Union service during the American Civil War. Organized in August 1861, the regiment served in the Army of the Potomac and was noted for its distinctive Zouave uniforms and its participation in many major campaigns of the Eastern Theater.
The regiment was mustered into United States service on August 10, 1861, and was initially composed of fifteen companies, numbering 1,487 men. The 72nd Pennsylvania Infantry was attached to the Philadelphia Brigade and saw action in numerous significant battles, including Antietam, Fredericksburg, Gettysburg, and the Overland Campaign.
Organization & Service
The 72nd Pennsylvania Infantry (Three Years’ Service) was organized in Philadelphia between August 3 and August 10, 1861, under the command of Colonel DeWitt Clinton Baxter. Many of its members had previously served with Baxter in the 19th Pennsylvania. After mustering in, the regiment moved to Washington, D.C., and was soon ordered across the Potomac to Virginia. On September 18, 1861, it was assigned to the Philadelphia Brigade under Colonel E. D. Baker. Shortly after, the regiment moved to Poolesville, Maryland, where it performed guard duty as part of General Stone’s division.
In the spring of 1862, the 72nd participated in the Peninsular Campaign as part of Sedgwick’s division, Sumner’s corps. The regiment suffered from sickness during the siege of Yorktown due to poor camp conditions and exposure. It saw action at Fair Oaks and was among the last to withdraw from the Chickahominy during the Seven Days’ Battles, suffering losses at Savage Station. The regiment was also present at Charles City Cross Roads and Malvern Hill.
Following the Peninsula Campaign, the 72nd moved with Sumner’s corps to support General Pope and then entered the Maryland Campaign. Under General Howard, the regiment fought at Antietam, incurring significant casualties. At Fredericksburg, under General Owen, the regiment again suffered losses. During the Chancellorsville Campaign, the 72nd was detached to assist engineers at Banks’ Ford and did not participate in the main battle. The regiment remained at Falmouth on guard and picket duty until June 1863.
During the Gettysburg Campaign, the 72nd was engaged at Thoroughfare Gap and Haymarket before arriving at Gettysburg on July 1, 1863. The regiment took position on the left center of the Union line and was heavily engaged during Pickett’s Charge on July 3, suffering severe losses. The regiment continued to serve in the fall campaigns of 1863, including actions at Bristoe Station and Robertson’s Tavern, and was present at Mine Run, though the planned assault was canceled.
In the winter of 1863–1864, the regiment was stationed near Stoneboro, performing guard duty along the Orange & Alexandria Railroad. The 72nd was active in the Overland Campaign, fighting at the Wilderness, Po River, Spotsylvania, and Cold Harbor. It crossed the James River in June 1864 and participated in the initial assaults on Petersburg and the advance on the Weldon Railroad. In August 1864, as the original members’ terms expired, veterans and recruits were transferred to the 183rd Pennsylvania Infantry. The remaining men were mustered out at Philadelphia on August 24, 1864.
