Service
1862
Once mustered, the regiment was immediately sent to Harrisburg, Pennsylvania on September 2, receiving their armaments before arriving at Washington, D.C., on September 3. Due to the dead not being buried in the aftermath of the Second Battle of Bull Run, the regiment was tasked to bury the dead for three days.[3]
After burying the dead on the field of Second Battle of Bull Run, the regiment was present on the Battle of Antietam but wasn't engaged, on the following day, the regiment moved towards the Potomac River, and engaged against the Confederates in a skirmish near Williamsport.[2]
The regiment was attached to Howe's Brigade of Couch's Division of the IV Corps of the Army of the Potomac where it replaced De Trobriand's 55th New York "Gardes Lafayette" on September 11, 1862. The composition of this brigade remained unchanged from this point until the war's end and included the 62d NY, 93d PVI, 98th PVI and the 102d PVI.[2]
1863
The 139th was transferred in October 1862 to the VI Corps. In the Battle of Fredericksburg, it suffered minor casualties from artillery fire, but didn't get a chance to fight. Five months later, however, it did participate in the 2nd Battle of Fredericksburg. At the Battle of Gettysburg in July, it helped defend the left flank of the Union army.[2]
1864
Throughout the spring and into early summer of 1864, the 139th fought in Grant's Overland Campaign and the early stages of the Siege of Petersburg. In July, it was transferred to Washington, D.C., with the rest of the VI Corps to defeat Lt. Gen. Jubal Early's attack on the city. Then they fought under Philip Sheridan in the Shenandoah Valley to ensure that no more Confederate armies would invade again. (See the article on the campaign). By December 1864, they were sent back to the siege lines of Petersburg.[2]
Later service
The 139th supported Sheridan in the Appomattox Campaign and fought in the Battle of Sailor's Creek. After the surrender of Lee and his army at Appomattox Courthouse, it was ordered to the North Carolina border to support William T. Sherman, but the Confederate surrender there made further support unnecessary. The regiment was mustered out June 21, 1865.[2]
