August 10, AD 955

Battle of Lechfeld (955)

Otto I defeats the Magyar army near Augsburg at the Battle of Lechfeld

The Magyars got behind Otto before the decisive clash, seized his baggage and sent three rear divisions running.

10 August 955, outside Augsburg

The Magyar army had been besieging Augsburg, where Bishop Ulrich with his knights and the city's inhabitants held out on 8 and 9 August 955. News that Otto I's relief army was approaching made the besiegers break off the siege and seek battle.

On the generally accepted chronology the armies met near Augsburg on 10 August. Thietmar dates it to St Lawrence's Day; Ruotger gives 9 August.

The battlefield has never been identified archaeologically, so Lechfeld should not be treated as a securely located spot.

The rear collapses, then recovers

Widukind reports that the Magyars crossed the Lech, struck Otto's rear, seized the baggage and routed successive rear divisions.

Duke Conrad the Red's Franconian division recovered the prisoners and booty and broke up the attackers; the main engagement then ended in a decisive defeat and eastward flight of the Magyar army.

Conrad was among Otto's dead.

The days after

Otto reached Augsburg by late afternoon. River crossings farther east were guarded, turning the pursuit over the following days into a wider destruction of the retreating forces.

Bulcsú, Lél and Súr were captured and transported to Regensburg, where they were hanged — not at Augsburg.

Widukind alone reports an imperial acclamation on the battlefield; the Augsburg historical project warns that it is uncorroborated and that Otto did not begin styling himself emperor afterwards.

Date disputed. Sources disagree about when this happened.

What the sources leave uncertain

Thietmar dates the battle to St Lawrence's Day, 10 August, but Ruotger gives 9 August. Ten August remains the conventional date.
The precise battlefield has not been identified archaeologically; 'Lechfeld' should not be treated as a securely located spot south of Augsburg.
No trustworthy total exists for either army. Widukind's eight legiones cannot safely be converted into the article's 7,000–9,000 men.
The detailed reconstruction of the battle and pursuit depends chiefly on two partisan near-contemporary narratives, Widukind and Gerhard.
