Since the states were responsible for Militia Pay Rolls during the Revolutionary War, and Camp Security was guarded by York County Militia during much of its existence, the Pennsylvania State Archives is the place to look for individual names.
Pennsylvania State Archives, RG-4, Records of the Comptroller General. Military Accounts, Militia, York County 1777-1794 contains hundreds of original discharges. Years after the end of their service at Camp Security, the soldiers were still seeking their full pay. Eventually, they were requested to show or turn in their discharge and “receive the interest and a new certificate for the full principal” to William Scott, the Lieutenant for York County Militia. I have been perusing those discharges on microfilm at the State Archives.
Since some soldiers had moved away, were ill, had sold their rights to the pay to others or authorized others to act as their agents, many have assignments accompanying the discharge or noted on the discharge themselves. Some are accompanied by formal Powers of Attorney, but most assignments are on a separate slip of paper or noted on the discharges themselves, usually signed by one witness. If the soldier served as a substitute, both are named.
The discharges themselves were handwritten, not many words on a small piece of paper, as you can see by the examples from the microfilm pictured and transcribed below. I have chosen several from December 1781 mentioning the stockade building precipitated by the new influx of British prisoners surrendered at Yorktown, Virginia. Note: Many of the Captains spelled tour as tower.
