== The Source == 

 It should be mentioned that the only surviving source for Ljudevit are Einhardt's annals, and since Einhard always glorified the Franks successes and usually didnt mention their defeats, the view on the entire event is pro-Frankish. An example is the fact that Einhard never mentions Franksih defeat, instead saying things like "they returned leaving their work mostly undone". Another is the amount of casualties Ljudevit suffers - 3000 men would be crippling casualties for a small early medieval state.
