"The rate of cannon-fire was very slow. The process of sponging-out and reloading was deliberate and complex. Powder was kept in small budge barrels near the guns, which were fired by the application of linstock to the touch-hole. The risk of premature explosions was very great, and it is doubtful whether it was possible to fire more than one round every three minutes. By the time of Waterloo it was possible, using grapeshot, to get off as many as three rounds a minute for short periods. With grape-shot the recoil was reduced and it was not necessary to run the guns up between rounds. But by 1815 all sorts of improvements had been made, with guns lightened and means of traction improved."
