30th. Started at 2am and struck the Petersburg and Norfolk
RR, marched up in the rear of the 9th Army Corps and layed
down on the tracks at dawn. We were all startled by a terrific explosion
and convulsive heaving of the Earth and, on looking over to the Enemy's
position, we beheld one of the Enemy forts blown into the air. The
sight was horrid; men, cannon and sticks of timber shooting in the
air in all directions and these descending again to the earth. The
shock was so terrific that it rolled our men off the bank of the RR
down on the tracks [at] a distance of 3/4 of a mile from the mine.
Immediately after the explosion our forces charged the enemy's position
and all of the Artillery on both sides was opened. The noise was so
great that you could not hear a man by your side speak. The fight
lasted until noon when our forces withdrew from the contest and we
returned to our camp.
