The French were equipped with bronze, rifled muzzle-loading artillery, while the Prussians used new steel breech-loading guns, which had a far longer range and a faster rate of fire. Prussian gunners strove for a high rate of fire, which was discouraged in the French army in the belief that it wasted ammunition. In addition, the Prussian artillery batteries had 30% more guns than their French counterparts. The Prussian guns typically opened fire at a range of 2–3 kilometres (1.2–1.9 mi), beyond the range of French artillery or the Chassepot rifle. The Prussian batteries could thus destroy French artillery with impunity, before being moved forward to directly support infantry attacks.
