Thursday, 1st—A heavy fog this morning. Our division crossed the Ogeechee river early this morning, the other two divisions of the corps having crossed last night. We crossed near Benton Station on the Savannah railroad. Our brigade destroyed the railroad this forenoon all the way from Benton Station north to Sebastopol on the road running to Augusta. Our entire corps destroyed about fifteen miles of railroad. We left Sebastopol about noon, and after marching eight miles through swamps, went into bivouac at dark. All is quiet.
