The night was unusually bright, and we expected to find the gunboat within a mile or so; but, after pulling down the river fully three miles, and not seeing the gunboat, I began to think she had turned and gone back to the sound; but we kept on, following the bends of the river, and about six miles below McAllister we saw her light, and soon were hailed by the vessel at anchor.  Pulling alongside, we announced ourselves, and were received with great warmth and enthusiasm on deck by half a dozen naval officers, among them Captain Williamson, United States Navy.  She proved to be the Dandelion, a tender of the regular gunboat Flag, posted at the mouth of the Ogeechee.  All sorts of questions were made and answered, and we learned that Captain Duncan had safely reached the squadron, had communicated the good news of our approach, and they had been expecting us for some days.  They explained that Admiral Dahlgren commanded the South-Atlantic Squadron, which was then engaged in blockading the coast from Charleston south, and was on his flag-ship, the Harvest Moon, lying in Wassaw Sound; that General J. G. Foster was in command of the Department of the South, with his headquarters at Hilton Head; and that several ships loaded with stores for the army were lying in Tybee Roads and in Port Royal Sound.  From these officers I also learned that General Grant was still besieging Petersburg and Richmond, and that matters and things generally remained pretty much the same as when we had left Atlanta.  All thoughts seemed to have been turned to us in Georgia, cut off from all communication with our friends; and the rebel papers had reported us to be harassed, defeated, starving, and fleeing for safety to the coast.  I then asked for pen and paper, and wrote several hasty notes to General Foster, Admiral Dahlgren, General Grant, and the Secretary of War, giving in general terms the actual state of affairs, the fact of the capture of Fort McAllister, and of my desire that means should be taken to establish a line of supply from the vessels in port up the Ogeechee to the rear of the army.  As a sample, I give one of these notes, addressed to the Secretary of War, intended for publication to relieve the anxiety of our friends at the North generally: 

ON BOARD DANDELION, OSSABAW SOUND, December 13, 1864—­11.50 p.m.

To Hon. E. M. STANTON, Secretary of War, Washington, D. C.: 

To-day, at 6 p. m., General Hazen’s division of the Fifteenth Corps carried Fort McAllister by assault, capturing its entire garrison and stores.  This opened to us Ossabaw Sound, and I pushed down to this gunboat to communicate with the fleet.  Before opening communication we had completely destroyed all the railroads leading into Savannah, and invested the city.  The left of the army is on the Savannah River three miles above the city, and the right on the Ogeechee, at King’s Bridge.  The army is in splendid order, and equal to any thing.  The weather has been fine, and supplies were abundant.  Our march was most agreeable, and we were not at all molested by guerrillas.
