Walnut Hills, near Vicksburg Mississippi
Lauman’s pickets arrested a party of men this morning making their way to Vicksburg. The spies had letters from Joe Johnston upon their persons, together with 200,000 percussion caps. They represent Johnston as being at Jackson in force. On my end of the line, there is no room for spies or messengers to sneak through. On the South end, McClernand does not stretch his troops all the way to the Mississippi and spies can sneak around the end of his line past the patrols.
