Apr 27 1862, Wrote Gen. Halleck, “Some of the Cavalry from Gen. McClernand’s Division have just returned from a little beyond the pickets having captured two negroes found skulking about. One of them reports having heard his master state that the enemy at Corinth intended making an attack on our forces today.
“This of course, it will be impossible to do, but it may foreshadow an intention of attacking.
“Shall I send for the negroes and forward them to you? I give all here that has been reported to me, officially, by Gen. McClernand.”
