The 9th New Jersey Infantry Regiment (also called Jersey Muskrats) was an American Civil War infantry regiment from New Jersey that served from October 1861 through July 1865 in the Union Army.[1][2] The regiment got its nickname, Jersey Muskrats, during the Battle of Roanoke Island when they successfully "sloshed through shoe sucking mud into waist deep water in "division" formation",[3] giving the regiment a two-company front flanking the enemy.[3] The regiment was the last to leave the state in 1861 but the first to see battle.[2]
The 9th took part in the Burnside Expedition into North Carolina. The regiment remained in North Carolina with the occupation force until early 1864 when the first enlistment was up. In January 1864 the regiment went back to New Jersey where more than 50% of those whose three-year term was about to expire reenlisted. This allowed the regiment to add "Veteran" to the name, a mark of distinction for the men. Those who reenlisted for three more years were given a 30-day veteran furlough. The regiment then moved into Virginia leading to the Siege of Petersburg. The 9th was then transferred back to North Carolina for garrison duty for the remainder of the war.
