Repeating rifles that could shoot up to seven times faster than the standard muzzleloading guns of the American Civil War might have given Northerners the victory in the first year of the four-year war. Even though they were a Union monopoly that had been patented before the war, few were deployed until the final year of fighting. Manufacturers could not understand the bureaucratic resistance and historians have argued over it ever since.

Southerners operated clandestinely to cause the Union Army Ordnance Bureau Chief to dismiss the weapons as unreliable "new fangled gimcracks." Firepower tells unravels the mystery of why the US Ordnance Bureau only slowly adopted them.
