Early this morning cannonading was begun in front of the Fifteenth Corps, followed by some lively skirmishing, and the rebels were routed from their works and driven across the Congaree river. The Fifteenth Corps then marched up along the south bank of the river above the city of Columbia, to the forks, where the Saluda and Broad rivers form the Congaree, and crossed the Saluda on the pontoons. In the meantime our regiment was behind on train guard and did not come into action. We moved forward and with our corps went into camp for the night on the south bank of the Congaree, just opposite Columbia, the state capital.
