He said he was in full communication with his department and was receiving supplies constantly.
Hardee, however, was cut off entirely from all communication with the west side of the river, and by the river itself to the north and south.
On the South Carolina side the country was all rice fields, through which it would have been impossible to bring supplies so that Hardee had no possible communication with the outside world except by a dilapidated plank road starting from the west bank of the river.

Sherman, receiving this reply, proceeded in person to a point on the coast, where General Foster had troops stationed under General Hatch, for the purpose of making arrangements with the latter officer to go through by one of the numerous channels running inland along that part of the coast of South Carolina, to the plank road which General Hardee still possessed, and thus to cut him off from the last means he had of getting supplies, if not of communication.
While arranging for this movement, and before the attempt to execute the plan had been commenced, Sherman received information through one of his staff officers that the enemy had evacuated Savannah the night before.
This was the night of the 21st of December.

Before evacuating the place Hardee had blown up the navy yard.

Some iron-clads had been destroyed, as well as other property that might have been valuable to us; but he left an immense amount of stores untouched, consisting of cotton, railroad cars, workshops, numerous pieces of artillery, and several thousand stands of small arms.
A little incident occurred, soon after the fall of Savannah, which Sherman relates in his Memoirs, and which is worthy of repetition.
Savannah was one of the points where blockade runners entered.

Shortly after the city fell into our possession, a blockade runner came sailing up serenely, not doubting but the Confederates were still in possession.
It was not molested, and the captain did not find out his mistake until he had tied up and gone to the Custom House, where he found a new occupant of the building, and made a less profitable disposition of his vessel and cargo than he had expected.
As there was some discussion as to the authorship of Sherman's march to the sea, by critics of his book when it appeared before the public, I want to state here that no question upon that subject was ever raised between General Sherman and myself.
