Departure and arrival of prisoners.
--Eight hundred and fifteen Abolition prisoners of war were sent from Richmond to City Point at 4 o'clock yesterday morning, and four hundred more will be gotten ready for exit this morning. The boat that conveyed away these followers of old Abe brought to City Point 215 Southern citizens, who had been, in the last eight months, seized by the minions of Lincoln in various places, and confined in dungeons. On being brought to Petersburg on Monday they were carried to the Model Farm barracks, and from thence many of them, on yesterday, made their way to this city. It is said that among these prisoners is Rev. Dr. Wilmer, an Episcopalian clergyman, who was taken prisoner while on his way to Europe from the South on a religious mission.Notice was given yesterday evening of the arrival of another flag of-truce boat at City Point containing 164 prisoners, only twenty of whom were citizen prisoners. Eleven Abolition prisoners arrived at the Libby on yesterday--eight from Weldon, N. C., and three from Staunton. The latter belonged to the 8th N. Y. cavalry, and were captured at Dumiries on the 30th March. The departure of this morning will leave only 437 Yankees of all grades in the Libby prison.
