Sunday, 4th—Rain last night. The First and Third Divisions and the First Brigade of the Fourth Division destroyed the railroad this forenoon for a distance of ten miles. The Iowa Brigade acted as train guard. We covered fifteen miles today and went into bivouac near Cameron Station. For the last two or three days, we marched through fine country, though in some places it is very sandy and the land is heavily timbered with pine. The soil is very sandy, but the higher land is well improved and thickly settled. Good crops were raised the past season, the work having been done by old men and negro women. Most of the citizens have left their homes.
