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 to 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. The Hungarians laid siege to Augsburg on the river Lech. Otto I advanced to relieve the city with an army of 8,000 heavy cavalry and infantry, divided into eight legions. As Otto I approached Augsburg on 10 August, a Hungarian surprise attack destroyed the Duchy of Bohemia rearguard legion. The Hungarian force stopped to plunder the German camp and Conrad, Duke of Lorraine led a counter-attack with heavy cavalry, dispersing the Hungarians. Otto I then brought his army into battle against the main Hungarian army that barred his way to Augsburg.
