The fortifications at Centerville (distinguished by the letters of the alaphabet), have the number of embrasures, and wooden guns pointing terrifically through them, as stated below:
Batteries Embrasures Wooden Guns
A 7 7
B 7 6
C 3 1
D 7 3
E 5 -
F 9 9
G 6 7
H 5 5
I 4
Number of embrasures 54
Number of wooden guns 31
The guns were pine logs, charred black with muzzles delineated with chalk, and properly protruded from the embrasures. No real guns had ever been mounted. This was the representation made by the Negroes, and the appearance inside of the work proves this representation to be correct. A Negro, who had been kept at work for months by the Confederates, reports them as having said that these pine logs would answer just as well to "skeer the enemy."
Here black confederates did not fire a shot in battle because they didn't have to.
