Michael von Kienmayer was an Austrian general. Kienmayer joined the army of the Habsburg monarchy and fought against the Kingdom of Prussia and Ottoman Turkey. During the French Revolutionary Wars, he continued to make his reputation in the cavalry and became a general officer. In the War of the Second Coalition and the Napoleonic Wars he commanded both divisions and corps. He was appointed Proprietor (Inhaber) of an Austrian cavalry regiment in 1802 and held this honor until his death. Later he was the governor of Galicia, Transylvania, and Moravia.

The Battle of Ebelsberg, known in French accounts as the Battle of Ebersberg, was fought on 3 May 1809 during the War of the Fifth Coalition, part of the Napoleonic Wars. The Austrian left wing under the command of Johann von Hiller took up positions at Ebersberg on the Traun river. The French under André Masséna attacked, crossing a heavily defended 550-meter-long bridge and subsequently conquering the local castle, thus forcing Hiller to withdraw. Ebelsberg is now a southern suburb of Linz, situated on the south bank of the Traun, a short distance above the place where that stream flows into the Danube River.
