The Magyars had followed up their victory…

The Magyars had followed up their victory at the battle of Pressburg by occupying lands up to the Enns River in the west and beginning punitive expeditions, usually one per year, against the German principalities, sometimes crossing the Rhine to harass Alsace and eastern France, Burgundy in particular.

Louis himself has tried to take some military control as he has grown older, but he has little success against the Magyars, who had raided Bavaria in 909, had been defeated, and return again in 910 to defeat a Bavarian army at Ennsburg (Lorch).
