Meanwhile the army with its stores had been gathering on a fleet of boats between Fort Henry and the railroad bridge. To the three divisions of Fort Donelson, First, Second, and Third, commanded by C.F. Smith, McClernand, and Lewis Wallace, were added a fourth, commanded by Brigadier-General S.A. Hurlbut, and a fifth by Brigadier-General W. T. Sherman. While C.F. Smith commanded the expedition, his division was commanded by W.H.L. Wallace, who had been promoted to brigadier-general. The steamer Golden State, with one-half of the Fortieth Illinois, reached Savannah, on the right bank of the river, on March 5th. The Forty-sixth Ohio arrived the next day. Behind these was the fleet of more than eighty steamboats, carrying the five divisions and convoyed by three gunboats, a vast procession extending miles along the winding river, each boat with its pillar of smoke by day, and of fire by night. The fleet began arriving at Savannah on the 11th, and lined both shores of the river. Lewis Wallace's division sent a party to the railroad west of the river, striking it at Purdy, tearing up a portion, but doing no permanent injury, and returned. On the 14th, General Smith sent Sherman's division up the river to strike the railroad near Eastport. Rain fell in torrents, roads melted into mud, and small streams rose with dangerous rapidity. The expedition, arrested by an unfordable torrent, returned just in time to reach the landing by wading through water waist-deep. The boats left in the night of the 15th, and stopped at Pittsburg Landing, on the west bank of the river, about nine miles above Savannah. Hurlbut's division was already on boats at this landing, having been ordered thither by General C.F. Smith on the evening of the 14th.
