had only seventeen pieces of artillery; and at the battle of Ivry the French had only four pieces of cannon, and two culverins: the army of the League had also only four pieces.

At the battle of Moncontour the opposing armies had but eight pieces each.
Gustavus Adolphus of Sweden not only improved the character of artillery, but also gave to it great development as an arm of service.
At the battle of Breetenfield he had one hundred pieces of artillery, great and small, and at the camp of Nuremberg he numbered about three hundred.

This king also made a more skilful use of his cannon by uniting them more in mass than had been done by his predecessors; his system was nevertheless very imperfect.

In the disposition of this arm on the field of battle, a vast improvement was made by Conde, Turenne, and Prince Eugene of Savoy.

Frederick the Great also made great use of this arm, and was the first to introduce horse artillery.
