Over the 20 years that Fort Knox was under construction, plans for the fort changed and parts of it had to be rebuilt. Such changes occurred in Battery B. This battery, built in 1845 for 15 guns, was the first place ready for cannons. Even though the battery was essentially complete, no cannons arrived.

Fort Knox's Battery B and Battery A (530 feet to the south), still had no cannons when the Civil War began in 1861.

The cannon emplacements in Batteries A and B had been made originally for 32-pounder cannons.
