General B. R. Johnson led the Rebel column, and Colonel Baldwin's brigade the advance. It was composed of the First and Fourteenth Mississippi and the Twenty-sixth Tennessee regiments. The next brigade was Colonel Wharton's. It was composed of the Fiftieth and Fifty-first Virginia. McCousland's brigade was composed of the Thirty-sixth and Fifty-sixth Virginia; Davidson's brigade was composed of the Seventh Texas, Eighth Kentucky, and Third Mississippi; Colonel Drake's brigade was composed of the Fourth and Twentieth Mississippi, Garven's battalion of riflemen, Fifteenth Arkansas, and a Tennessee regiment. Hieman's brigade was composed of the Tenth, Thirtieth, and Forty-eighth Tennessee, and the Twenty-seventh Alabama. There were about thirty pieces of artillery, and twelve thousand men in this column. McArthur's brigade of McClernand's division was on the extreme right, and a short distance in rear of Oglesby. The Rebels moved down the Union Ferry road, which leads southwest towards Clarksville, which brought them nearly south of Oglesby and McArthur. Oglesby's regiments stood, the Eighth Illinois on the right, then the Twenty-ninth, Thirtieth, and Thirty-first, counting towards the left. Schwartz's battery was on the right and Dresser's on the left. Wallace's brigade was formed with the Thirty-first Illinois on the right, close to Oglesby's left flank regiment, then the Twentieth, Forty-eighth, Forty-fifth, Forty-ninth, and Seventeenth Illinois. McAllister's battery was between the Eleventh and Twentieth, and Taylor's between the Seventeenth and Forty-ninth. Colonel Dickey's cavalry was in rear, his horses picketed in the woods and eating corn. North of the Fort Henry road was Colonel Cruft's brigade of General Lewis Wallace's division, the Twenty-fifth Kentucky having the right, then the Thirty-first Indiana, the Seventeenth Kentucky, the Forty-fourth Indiana, with Wood's battery. These are all the regiments which took part in the terrible fight of Saturday forenoon. They were unprepared for the assault. The soldiers had not risen from their snowy beds. The reveille was just sounding when the sharp crack of the rifles was heard in the thickets on the extreme right. Then the artillery opened. Schwartz's, Dresser's, McAllister's, and Taylor's men sprang from their blankets to their guns. It was hardly light enough to see the enemy. They could only distinguish the flashes of the guns and the wreaths of smoke through the branches of the trees; but they aimed at the flashes, and sent their shells upon the advancing columns. The Rebel batteries replied, and the wild uproar of the terrible day began.
