:The 4th New Jersey Infantry was reorganized at Camp Olden in Trenton for three years service on August 19, 1861 under the command of Colonel James H. Simpson.
The regiment was attached to Kearney's Brigade, Division of the Potomac, to October 1861. Kearney's Brigade, Franklin's Division, Army of the Potomac, to March 1862. 1st Brigade, 1st Division, I Corps, Army of the Potomac, to April 1862. 1st Brigade, 1st Division, Department of the Rappahannock, to May 1862. 1st Brigade, 1st Division, VI Corps, Army of the Potomac and Army of the Shenandoah, to July 1865.
The regiment was surrounded at Gaines Mill and most of its men taken prisoner. After the Seven Days Battles, they were freed by the Confederate authorities in a prisoner exchange. The 4th New Jersey had been armed with M1861 Springfield rifles, however upon returning from captivity, the authorities in Washington had no rifled muskets to rearm the regiment with, thus they were given outdated .69 smoothbore muskets. The regiment was forced to use them until the Battle of South Mountain in September, when they rearmed themselves with Enfield rifles dropped by retreating Confederates.Information
