I was disappointed that Hardee had escaped with his army, but on the whole we had reason to be content with the substantial fruits of victory. The Savannah River was found to be badly obstructed by torpedoes, and by log piers stretched across the channel below the city, which piers were filled with the cobble stones that formerly paved the streets. Admiral Dahlgren was extremely active, visited me repeatedly in the city, while his fleet still watched Charleston, and all the avenues, for the blockade-runners that infested the coast, which were notoriously owned and managed by Englishmen, who used the island of New Providence (Nassau) as a sort of entrepot. One of these small blockade-runners came into Savannah after we were in full possession, and the master did not discover his mistake till he came ashore to visit the custom-house. Of coarse his vessel fell a prize to the navy. A heavy force was at once set to work to remove the torpedoes and obstructions in the main channel of the river, and, from that time forth, Savannah became the great depot of supply for the troops operating in that quarter.
Meantime, on the 15th and 16th of December, were fought, in front of Nashville, the great battles in which General Thomas so nobly fulfilled his promise to ruin Hood, the details of which are fully given in his own official reports, long-since published. Rumors of these great victories reached us at Savannah by piecemeal, but his official report came on the 24th of December, with a letter from General Grant, giving in general terms the events up to the 18th, and I wrote at once through my chief of staff, General Webster, to General Thomas, complimenting him in the highest terms. His brilliant victory at Nashville was necessary to mine at Savannah to make a complete whole, and this fact was perfectly comprehended by Mr. Lincoln, who recognized it fully in his personal letter of December 26th, hereinbefore quoted at length, and which is also claimed at the time, in my Special Field Order No. 6, of January 8, 1865, here given:
