At the Battle of Leuthen in 1757, Frederick's nascent mobile artillery kept pace with the rapidly-moving infantry and laid devastating barrages upon the Austrian lines. Officially, Frederick's first horse artillery detachment, created through a Cabinet Order in April 1759, included six 6–pound guns, referred to as "light" guns. The types of guns might include 6–pound guns, a 7–pound howitzer, and 3–pound guns. The horse artillery was lost at Kunersdorf, replaced quickly, and then lost again at Maxen.
