We reached Savannah three days ago, but, owing to Fort McAllister, could not communicate; but, now that we have McAllister, we can go ahead.

We have already captured two boats on the Savannah river and prevented their gunboats from coming down.

I estimate the population of Savannah at twenty-five thousand, and the garrison at fifteen thousand.  General Hardee commands.

We have not lost a wagon on the trip; but have gathered a large supply of negroes, mules, horses, etc., and our teams are in far better condition than when we started.

My first duty will be to clear the army of surplus negroes, mules, and horses.  We have utterly destroyed over two hundred miles of rails, and consumed stores and provisions that were essential to Lee’s and Hood’s armies.

The quick work made with McAllister, the opening of communication with our fleet, and our consequent independence as to supplies, dissipate all their boasted threats to head us off and starve the army.

I regard Savannah as already gained. 
Yours truly,

W. T. SHERMAN, Major-General.

By this time the night was well advanced, and the tide was running ebb-strong; so I asked.  Captain Williamson to tow us up as near Fort McAllister as he would venture for the torpedoes, of which the navy-officers had a wholesome dread.  The Dandelion steamed up some three or four miles, till the lights of Fort McAllister could be seen, when she anchored, and we pulled to the fort in our own boat.  General Howard and I then walked up to the McAllister House, where we found General Hazen and his officers asleep on the floor of one of the rooms.  Lying down on the floor, I was soon fast asleep, but shortly became conscious that some one in the room was inquiring for me among the sleepers.  Calling out, I was told that an officer of General Fosters staff had just arrived from a steamboat anchored below McAllister; that the general was extremely anxious to see me on important business, but that he was lame from an old Mexican-War wound, and could not possibly come to me.  I was extremely weary from the incessant labor of the day and night before, but got up, and again walked down the sandy road to McAllister, where I found a boat awaiting us, which carried us some three miles down the river, to the steamer W. W. Coit (I think), on board of which we found General Foster.  He had just come from Port Royal, expecting to find Admiral Dahlgren in Ossabaw Sound, and, hearing of the capture of Fort McAllister, he had come up to see me.  He described fully the condition of affairs with his own command in South Carolina.  He had made several serious efforts to effect a lodgment on the railroad which connects Savannah with Charleston near Pocotaligo, but had not succeeded in reaching the railroad itself, though he had a full division of troops, strongly intrenched, near Broad River, within cannon-range of the railroad.  He explained,
