T. A. Henderson, Provost-Marshal of the district of Florida, issued the following circular from his headquarters at Jacksonville:
All refugees from the rebel lines, and deserters from the rebel armies, and all persons desiring to become such, are hereby informed that they will not, under any circumstances, be compelled to serve in the United States army against the rebels. This assurance is fully given in General Orders Number Sixty-four, of date February eighteenth, 1864, from the War Department. All such refugees and deserters, who are honest in their intentions of for ever deserting the rebel cause, will be allowed every opportunity of engaging in their usual avocations; or, if they desire employment from the United States, will, as far as expedient, be employed on the government works, receiving proper compensation for their services. All refugees or deserters who may bring horses or mules into the Union lines will be paid their full value.
