just to stay around the wagon, the municipal infantry they organized themselves into a semicircle defensive system. The position of the lances within this formation, all facing outwards, was certainly another reason for the victorious resistance, given that it constituted a defensive bulwark that could not be easily overcome Furthermore, the municipal troops, grouped on a territorial basis, were linked by kinship or neighborhood relations, which contributed to further compacting the ranks. In addition to fighting for their fellow soldiers, the municipal soldiers also fought for the freedom of their city and to defend their possessions and this led to a further stimulus to resistance against the enemy. This battle is one of the first examples in which the medieval infantry could demonstrate its tactical potential towards the cavalry. The merit of the victory of the municipal troops must however also be shared with the light cavalry, which came later, which carried out the decisive charge against the imperials. Origins and places of battle At centuries of distance, given the scarcity of authentic information written by contemporary chroniclers at the events, it is difficult to establish precisely where the clashes took place. The chronicles of the epoch that deal with the battle of Legnano are in fact short writings formed by a number of words between one hundred and two hundred; the exception is the Life of Alexander III written by Boso Breakspeare, which reaches four hundred words. On some occasions there is the problem of the distortion of toponyms made by the copyists of the time, who did not know the geography of the area. The contemporary sources that deal with the battle of Legnano are divided into three categories: the chronicles written by the Milanese or by the federated cities in the Lombard League, those written by the imperials or their allies and the ecclesiastical documents of the papal party. The contemporary Milanese chronicles unanimously report that the battle was fought de, apud, iuxta, ad Lignanum or inter Legnanum et Ticinum. Among them stands a document compiled by two anonymous chroniclers (Gesta Federici I imperatoris in Lombardy. Trad. "The exploits of Emperor Frederick I in Lombardy"), whose two parts of the text, written by an unknown reporter between 1154 and 1167 and the other completed by another anonymous in 1177, they were copied in 1230 by Sire Raul.
