Gulf. The Mississippi levee cuts the supply of water off from these
bayous or channels, but all the rainfall behind the levee, at these
points, is carried through these same channels to the river below. In
case of a crevasse in this vicinity, the water escaping would find its
outlet through the same channels. The dredges and laborers from the
canal having been driven out by overflow and the enemy's batteries, I
determined to open these other channels, if possible. If successful the
effort would afford a route, away from the enemy's batteries, for our
transports. There was a good road back of the levees, along these
bayous, to carry the troops, artillery and wagon trains over whenever
the water receded a little, and after a few days of dry weather.
Accordingly, with the abandonment of all the other plans for reaching a
base heretofore described, this new one was undertaken.

As early as the 4th of February I had written to Halleck about this
route, stating that I thought it much more practicable than the other
undertaking (the Lake Providence route), and that it would have been
accomplished with much less labor if commenced before the water had got
all over the country.

The upper end of these bayous being cut off from a water supply, further
than the rainfall back of the levees, was grown up with dense timber for
a distance of several miles from their source. It was necessary,
therefore, to clear this out before letting in the water from the river.
This work was continued until the waters of the river began to recede
and the road to Richmond, Louisiana, emerged from the water. One small
steamer and some barges were got through this channel, but no further
use could be made of it because of the fall in the river. Beyond this it
was no more successful than the other experiments with which the winter
was whiled away. All these failures would have been very discouraging
if I had expected much from the efforts; but I had not. From the first
the most I hoped to accomplish was the passage of transports, to be used
below Vicksburg, without exposure to the long line of batteries
defending that city.

This long, dreary and, for heavy and continuous rains and high water,
unprecedented winter was one of great hardship to all engaged about
Vicksburg. The river was higher than its natural banks from December,
1862, to the following April. The war had suspended peaceful pursuits
in the South, further than the producti
