I have received intelligence that Confederate President Davis may attempt to cross the Mississippi at Vicksburg on his way presumably to Mexico. I wrote Gen. Dana,
WASHINGTON, April 30, 1865 – 1 p. m.
Station troops at Rodney or that vicinity at once, with cavalry to patrol the river and prevent all rebels from crossing it. It is probable Davis and his cabinet will try to cross. If they do it will be between the mouth of Big Black and Natchez. Call upon the navy for co-operation, and make every preparation to intercept him if he should. Notify commander at Baton Rouge to the same effect and communicate your action.
