John D. Billings, Hardtack and Coffee: The Unwritten Story of Army Life

After arriving before Fort McAllister, General Sherman sent General Hazen down the right bank of the Ogeechee to take the fort by assault, and himself rode down the left bank to a rice plantation, where General Howard had established a signal station to overlook the river and watch for vessels. The station was built on the top of a rice-mill. From this point the fort was visible, three miles away. In due time a commotion in the fort indicated the approach of Hazen's troops, and the signal officer discovered a signal flag about three miles above the fort, which he found was Hazen's, the latter inquiring if Sherman was there. He was answered affirmatively, and informed that Sherman expected the fort to be carried before night. Finally Hazen signalled that he was ready, and was told to go ahead.

“Is Fort McAllister taken?”

“ Not yet; but it will-be in a minute.”

And in a few minutes it was taken, and the fact signalled to the naval officers on the boat, who were not in sight of the fort.

At that moment, however, General Warren of the Fifth Corps appeared, and ordered them to keep their signals waving as if a host were immediately behind them, which they did.
