Jan 29 1863. Arriving at Vicksburg, I gave an update to Gen. Halleck on the condition of the canal project.
January 29, 1863-5 p. m.
Major General H. W. HALLECK,
Water in the canal is 5 feet deep, and river rising. There is no wash, however, and no signs of its enlarging. I will let the water in from the Yazoo up, and try the effect. I have ordered troops from Helena, escorted by a gunboat, the whole in charge of Colonel Wilson, topographical engineer, to cut the levee across Yazoo Pass, and to explore through to the Coldwater, if possible.
