Thursday, 26th—We left our bivouac at 6 o’clock this morning and marched twelve miles. Within a few miles of Decatur we went into bivouac for the night. Advance brigades of our army were skirmishing with the rebels today and it is reported that the colonel of the Seventeenth New Jersey Regiment was killed. Our men captured a provision train and also took some prisoners. Our corps teams have been sent out for fodder.
