JANUARY 3RD, 1865: Rear Admiral Dahlgren returned to Savannah after a brief visit to Charleston where he had gone because of the threat of a breakout of the Confederate ironclads at that place. He had been there to help check any attempt to breakout and then probably attack on Savannah and to insure "the perfect security of General Sherman's base."
After stationing a force of seven monitors at Charleston, sufficient to meet a breakout attempt, "and not perceiving any sign of the expected raid, I returned to Savannah to keep in communication with General Sherman and be ready to render any assistance that might be desired.
"General Sherman has fully informed me of his plans, and so far as my means permit, they shall not lack assistance by water....
"The general route of the army shall be northward, but the exact direction must be decided more or less by circumstances which it may not be possible to foresee."
