Pennsylvania Governor Andrew Curtin ordered local workers to erect a series of forts and earthworks to protect the city, which then had a population of 13,000 residents.
In response, Union Maj. Gen. Darius N. Couch, commanding the Department of the Susquehanna, dispatched troops to the present day borough of Camp Hill, located in the Cumberland Valley approximately two miles west of Harrisburg.
Brigadier General William F. Smith, commanding the 1st Division of the Department of the Susquehanna, sent two militia infantry regiments and a cavalry company to locate the Confederates.

The State Museum of Pennsylvania in downtown Harrisburg has a modest, but historically significant collection of artifacts, paintings, and war relics.
