On the 30th of January, the day after my arrival at the front, I ordered
General McPherson, stationed with his corps at Lake Providence, to cut
the levee at that point. If successful in opening a channel for
navigation by this route, it would carry us to the Mississippi River
through the mouth of the Red River, just above Port Hudson and four
hundred miles below Vicksburg by the river.

Lake Providence is a part of the old bed of the Mississippi, about a
mile from the present channel. It is six miles long and has its outlet
through Bayou Baxter, Bayou Macon, and the Tensas, Washita and Red
Rivers. The last three are navigable streams at all seasons. Bayous
Baxter and Macon are narrow and tortuous, and the banks are covered with
dense forests overhanging the channel. They were also filled with
fallen timber, the accumulation of years. The land along the
Mississippi River, from Memphis down, is in all instances highest next
to the river, except where the river washes the bluffs which form the
boundary of the valley through which it winds. Bayou Baxter, as it
reaches lower land, begins to spread out and disappears entirely in a
cypress swamp before it reaches the Macon. There was about two feet of
water in this swamp at the time. To get through it, even with vessels
of the lightest draft, it was necessary to clear off a belt of heavy
timber wide enough to make a passage way. As the trees would have to be
cut close to the bottom--under water--it was an undertaking of great
magnitude.

On the 4th of February I visited General McPherson, and remained with
him several days. The work had not progressed so far as to admit the
water from the river into the lake, but the troops had succeeded in
drawing a small steamer, of probably not over thirty tons' capacity,
