Yankee Prisoners. – Thirty odd Yankee prisoners, captured at Deep Bottom yesterday, have been brought to this city and committed to the Libby prison. They were from the 20th Massachusetts regiment, and among them was 1st Lient. A. G. Sedgwick, Adjutant to the regiment. Fifteen were Germans, and from them we learn that there were three hundred foreigners in the 20th Massachusetts who were regularly enlisted in the Yankee service before leaving Germany for the United States.
