Five years later, the armies of the Czechs and Germans allied against the Magyars in the victorious Battle of Lechfeld on 10 August 955. After the battle, the remainder of the huge Magyar army turned to Bohemia, where it was crushed by Boleslaus. Shortly afterwards, in October, he also helped Otto to crush an uprising of Slavic tribes led by the Obotrite princes Nakon and Stojgněv on the Lower Elbe river in the Battle on the Raxa.
