The purpose of this paper is to analyze the difference in our picture of three events on the early iron age battlefields depending on the material that is examined. This paper is basing the comparative analysis on historical texts and archaeological findings to analyze the three battles: battle of Alesia, battle of Teutoburg forest and battle of Harzhorn. The theoretical framework of this paper is built on battlefield archaeology, all three battlefields have been archaeologically excavated to different extents using this method.    The historical and archaeological material has presented both varying and the same picture of the battlefields. For the battle of Alesia, the historical materials depiction of the battle is more extensive than the archaeological. For the battle of Teutoburg forest the archaeological materials depiction is more extensive than the historical but the historical material explains the event with more simplicity. Lastly for the battle of Harzhorn the archaeological materials depiction is much more extensive than the historical material.
