Yankee prisoners.
--Forty-five Abolition prisoners, who were captured at Kelley's ford on the 29th of April, arrived at the Libby prison on Saturday. They were mostly foreigners, and represented forty regiments, each man nearly belonging to a different one.--Speaking of Yankee prisoners reminds us to say that all the Yankee officers, (including the two Generals,) in number exceeding two hundred, and the privates and sailors, will be sent North under flag of truce on to-morrow, Judge Ould having arranged satisfactory terms with Col. Ludlow, the Federal Commissioner.The Central cars arrived last night, bringing 59 Yankees captured on Saturday in Spotsylvania county. They were lodged at the Libby prison.
