The Battle of Lechfeld, also known as the Second Battle of Lechfeld, was a series of military engagements over the course of three days from 10–12 August 955 in which the Kingdom of Germany, led by King Otto I the Great, defeated the Hungarian army led by Harka Bulcsú and the chieftains Lél and Súr. With the German victory, further major invasions by the Magyars into Western Europe were ended. The Hungarians invaded the Duchy of Bavaria in late June or early July 955 with 8,000–10,000 horse archers, infantry, and siege engines, intending to draw the main German army, under Otto I, into battle in the open field and destroy it.
