each other--where there was space enough between the lines to post
pickets--that the men could converse. On the 21st of June I was
informed, through this means, that Pemberton was preparing to escape, by
crossing to the Louisiana side under cover of night; that he had
employed workmen in making boats for that purpose; that the men had been
canvassed to ascertain if they would make an assault on the "Yankees" to
cut their way out; that they had refused, and almost mutinied, because
their commander would not surrender and relieve their sufferings, and
had only been pacified by the assurance that boats enough would be
finished in a week to carry them all over. The rebel pickets also said
that houses in the city had been pulled down to get material to build
these boats with. Afterwards this story was verified: on entering the
city we found a large number of very rudely constructed boats.

All necessary steps were at once taken to render such an attempt
abortive. Our pickets were doubled; Admiral Porter was notified, so
that the river might be more closely watched; material was collected on
the west bank of the river to be set on fire and light up the river if
the attempt was made; and batteries were established along the levee
crossing the peninsula on the Louisiana side. Had the attempt been made
the garrison of Vicksburg would have been drowned, or made prisoners on
the Louisiana side. General Richard Taylor was expected on the west
bank to co-operate in this movement, I believe, but he did not come, nor
could he have done so with a force sufficient to be of service. The
Mississippi was now in our possession from its source to its mouth,
except in the immediate front of Vicksburg and of Port Hudson. We had
nearly exhausted the country, along a line drawn from Lake Providence to
opposite Bruinsburg. The roads west were not of a character to draw
supplies over for any considerable force.
