The Krupp C64 (sometimes C/64) steel, breech loaded field gun (8 cm caliber, 4 pound projectile) was one of the main artillery pieces of the Prussians in the 1870-1871 war with France. It was superior to the French counterparts in every way: accuracy, rate of fire and range. The C64 was the sole gun of the horse artillery units. Each unit comprised three batteries, each battery was equipped with six C64 guns, for a total of eighteen guns per unit. The foot artillery units had an equal mixture of C64 and the heavier C67 (six pounder gun).
