July 2. Late in the evening the Napoleons were placed in position about 400 yards eastward from this point.
July 3. The Napoleons participated actively in all the operations of the artillery during the day including the cannonade preceding Longstreet’s assault withdrawing afterward to a position near here. The Howitzers were kept in the rear and took no part in the battle but were held in readiness to resist any advance of the Union forces.
