Battery E. — Capts., Joseph M. Knap, Charles A. Atwell, James D. McGill, James A. Dunlevy, Thomas S. Sloan. This battery was recruited at Pittsburg and mustered into the U. S. service for a three years term, at Point of Rocks, Md., where it was attached to the 28th regiment. Ordered to Washington for equipment, it remained there until Nov. 24, when it returned to Point of Rocks and in March 1862, it was posted at Salem and Front Royal on the Manassas Gap railroad. The detachment at Front Royal was attacked in May and forced to retire to Winchester. At Cedar mountain the battery was closely engaged and finally forced from its exposed position by the enemy's guns. At Antietam, it was active but did not reach the field at Fredericksburg in time to share in the battle. Winter quarters were established at Acquia creek and in the Chancellorsville campaign in the spring of 1863, the battery did effective service. At Gettysburg, attached to the 12th corps, it was actively engaged and then proceeded with the 11th and 12th corps to join the Army of the Cumberland at Chattanooga, Tenn., where it arrived on Oct. 29. It was attacked at Wauhatchie Junction, where it was encamped, and suffered heavily. It participated in the battles of Lookout mountain and Missionary ridge and went into winter quarters at Wauhatchie. In Jan., 1864, a large number of its members reenlisted and the battery continued in the field as a veteran organization. The 20th corps, which succeeded the 11th and 12th, was part of Gen. Sherman's army and with it the battery participated in the battles on the way to Atlanta, attached to Gen. Geary's division. It accompanied the 20th corps to Atlanta, then on the march to the sea, and at Raleigh, N. C., was detached and sent to Washington. On June 14, 1865, at Pittsburg, Battery E was mustered out after long and varied duty.
