May 29 1863. It is beginning to look like we will not be reinforced by Gen. Banks as he has launched an assault on Port Hudson. I wrote Gen. Halleck,
NEAR Vicksburg, May 29, 1863.
Major General H. W. HALLECK,
The enemy under Johnston is collecting in large force to attack me and rescue the garrison of Vicksburg. I have had my cavalry and six brigades of infantry out looking after them, and they confirm the report of a large force being collected at Canton.
The number is reported to be 45,000, but may not be so large. If Banks does not come to my assistance, I must be re-enforced from elsewhere. I will avoid surprise, and do the best I can with all the means at hand.
