THE YANKEE PRISONERS. - Between four hundred and five hundred of the Yankee wounded arrived in the city on Saturday, and over two hundred were sent to Belle Isle, in the James river, where they are cared for. Opposite the island are the quarters of the officers, called Crenshaw's Mills, where all the officers are confined. There are among the prisoners about a dozen surgeons, who are allowed to visit them under certain restrictions.
On Saturday two thousand letter were received from the prisoners, and examined in the Libby prison by Lieutenant Cook, aided by several assistants.
All of the letters breathe the same spirit - that of resignation to their fate. "All are treated well," so they say. All the letters commence with the remark, "I take my pen in hand," &c., "and hope this will find you the same," &c. About three hundred were received on Friday and two hundred on Saturday. A large number, about six hundred, has been sent to Belle Isle, in the James river. Others will follow them.
