This fort was situated on a high bluff, which descended precipitately to the river's edge, the side of the bluff on the river side being covered with trees, bushes, and fallen timber. Extending back from the river, on either side of the fort, was a ravine or hollow--the one below the fort containing several private stores and some dwellings, constituting what was called the town. At the mouth of that ravine, and on the river bank, were some government buildings containing commissary and quartermaster's stores. The ravine above the fort was known as Cold Creek ravine, the sides being covered with trees and bushes. To the right, or below and a little to the front of the fort, was a level piece of ground, not quite so elevated as the fort itself, on which had been erected some log huts or shanties, which were occupied by the white troops, and also used for hospital and other purposes. Within the fort tents had been erected, with board floors, for the use of the colored troops. There were six pieces of artillery in the fort, consisting of two 6-pounders, two 12-pounder howitzers, and two 10-pounder Parrotts. The rebels continued their attack, but, up to two or three o'clock in the afternoon, they had not gained any decisive success. Our troops, both white and black, fought most bravely, and were in good spirits. The gunboat No. 7, (New Era,) Captain Marshall, took part in the conflict, shelling the enemy as opportunity offered. Signals had been agreed upon by which the officers in the fort could indicate where the guns of the boat could be most effective. There being but one gunboat there, no permanent impression appears to have been produced upon the enemy; for as they were shelled out of one ravine, they would make their appearance in the other. They would thus appear and retire as the gunboat moved from one point to the other. About one o'clock the fire on both sides slackened somewhat, and the gunboat moved out in the river, to cool and clean its guns, having fired 282 rounds of shell, shrapnell, and canister, which nearly exhausted its supply of ammunition. The rebels having thus far failed in their attack, now resorted to their customary use of flags of truce. The first flag of truce conveyed a demand from Forrest for the unconditional surrender of the fort. To this Major Bradford replied, asking to be allowed one hour to consult with his officers and the officers of the gunboat. In a short time a second flag of truce appeared, with a communication from Forrest, that he would allow Major Bradford twenty minutes in which to move his troops out of the fort, and if it was not done within that time an assault would be ordered. To this Major Bradford returned the reply that he would not surrender.
