The French artillery was the military arm least affected by the chaos accompanying the French Revolution. By the Napoleonic Wars, the French realized that artillery had become one of the three main combat arms, together with infantry and cavalry. On a number of battlefields, the artillery won the day. As early as the Battle of Wattignies in 1793 a Coalition observer remarked that the "immense artillery" of the French was the decisive factor. French armies employed approximately two artillery pieces per 1,000 soldiers in 1800. Napoleon aimed for a ratio of five guns per 1,000, but this goal was never reached. As the quality of foot soldiers fell, the ratio was increased so that there were three guns per 1,000 men at the Battle of Leipzig in 1813. The 6-inch howitzers were commonly found in the divisional and army artillery reserves. The ideal battery was made up of eight field pieces, with six cannons and two howitzers. Batteries with four cannons and two howitzers were also seen frequently. In 1805 there were 8,320 howitzers of all types available for military use.
