Military Exemption Form

Though exemption forms, certificates and letters are mentioned now and again, the form below is the only one I have run across. It was created by the Richmond & Petersburg RR, so each railroad's form would be different. The number of exemptions each railroad could have was strictly controlled and reports (sometimes monthly) were required to show which employees were using the exemptions.
Office Richmond & Petersburg R. R. Co.
Richmond, Va. Oct 27, 1862
   I hereby verify that the bearer J. H. Woodcock is "in the active service and employment" of the Richmond and Petersburg Rail Road Company as Station Agent, and is therefore exempted from Military duty by the Military Exemption Act; as passed by both houses of Congress of the Confederate States, October, 1862.
