Though it was mid-winter, General Halleck was pushing his preparations most vigorously, and surely he brought order out of chaos in St. Louis with commendable energy. I remember, one night, sitting in his room, on the second floor of the Planters’ House, with him and General Cullum, his chief of staff, talking of things generally, and the subject then was of the much-talked-of “advance,” as soon as the season would permit. Most people urged the movement down the Mississippi River; but Generals Polk and Pillow had a large rebel force, with heavy guns in a very strong position, at Columbus, Kentucky, about eighteen miles below Cairo. Commodore Foote had his gunboat fleet at Cairo; and General U. S. Grant, who commanded the district, was collecting a large force at Paducah, Cairo, and Bird’s Point. General Halleck had a map on his table, with a large pencil in his hand, and asked, “where is the rebel line?” Cullum drew the pencil through Bowling Green, Forts Donelson and Henry, and Columbus, Kentucky. “That is their line,” said Halleck. “Now, where is the proper place to break it?” And either Cullum or I said, “Naturally the centre.” Halleck drew a line perpendicular to the other, near its middle, and it coincided nearly with the general course of the Tennessee River; and he said, “That’s the true line of operations.” This occurred more than a month before General Grant began the movement, and, as he was subject to General Halleck’s orders, I have always given Halleck the full credit for that movement, which was skillful, successful, and extremely rich in military results; indeed, it was the first real success on our side in the civil war. The movement up the Tennessee began about the 1st of February, and Fort Henry was captured by the joint action of the navy under Commodore Foote, and the land forces under General Grant, on the 6th of February, 1862. About the same time, General S. R. Curtis had moved forward from Rolls, and, on the 8th of March, defeated the rebels under McCulloch, Van Dom, and Price, at Pea Ridge.
As soon as Fort Henry fell, General Grant marched straight across to Fort Donelson, on the Cumberland River, invested the place, and, as soon as the gunboats had come round from the Tennessee, and had bombarded the water-front, he assaulted; whereupon Buckner surrendered the garrison of twelve thousand men; Pillow and ex-Secretary of War General Floyd having personally escaped across the river at night, occasioning a good deal of fun and criticism at their expense.
