To Mary Todd Lincoln 
Mrs. Lincoln: At 4:30 p.m. to-day General Grant telegraphs that he has Petersburg completely enveloped from river below to river above, and has captured, since he started last Wednesday, about 12,000 prisoners and 50 guns. He suggests that I shall go out and see him in the morning, which I think I will do. Tad and I are both well, and will be glad to see you and your party here at the time you name. A. LINCOLN.
