Departures by flag-of-truce.
--Four hundred and twenty-five wounded Yankee soldiers, nurses, &c., left this city yesterday morning in the steamer Schultz
, whence they will take the flag-of- truce boat North
in exchange for an equal number of Confederates now confined in Yankee prisons.
Among the number were sent from Castle Thunder the notorious Miss Doctor Mary E. Walker
of the Fifty-second Ohio regiment, Dr. Culbertson
, from Chambersburg, Pennsylvania
, and Captain Samuel Stears
, who was formerly a Yankee Custom-House
When Miss Dr. Walker
emerged from the confines of the Castle
she gave vent to an audible huzzah, and raising her hat from her head made an obeisance to the officers of the prison, which plainly indicated that she had no regrets in leaving there, and would remember them in her communications which would be made after her arrival home.
