Salimbene from Parma and the bishop of Crema also report apud Legnanum. The contemporary chronicles of the imperial part, on the other hand, do not specify the places of the conflict but merely describe the events; among the Teutonic documents, the most important are the annals of Cologne, the writings of Otto of Freising and the chronicles of Godfrey of Viterbo. The most important contemporary ecclesiastical sources are the writings of the Archbishop of Salerno and the Life of Alexander III drafted by Boso Breakspeare, with the first not referring to the indication of the places, and the second that report the crippled toponym of Barranum. Among the sources after the battle, Bonvesin da la Riva, who wrote about a century after the fight, stated that the battle had taken place "inter Brossanum et Legnanum", while Goffredo da Bussero, a contemporary of Bonvesin de la Riva, reported that "imperator victus a Mediolanensisbus inter Legnanum et Borsanum". The first phase of the battle, which is connected to the initial clash between the two armies, seems to have taken place between Borsano and Busto Arsizio. This thesis is supported, among other things, by the document of the two anonymous chroniclers, where it is said that: As for the final stages of the battle, which are connected to the defense of the Carroccio and the subsequent and resolute clashes between the two armies, the Life of Alexander III of Boso Breakspeare, contemporary with the battle, provides an important indication: in this text we indicate the toponyms, evidently crippled by the copyists, of Barranum and Brixianum, which could indicate Legnano and Borsano or Busto Arsizio and Borsano, and the precise distance between the site of the last phases of the battle and Milan, 15 miles (about 22 km), which is the exact distance between Legnano and the Lombard capital. This distance of 15 miles was then used to refer to Legnano also in subsequent documents. In fact, in the Life of Alexander III we read that: The same source also mentions the distance of 3 miles (about 4.5 km) from Legnano in reference to the first contact of the two armies, confirming the hypothesis that this phase of the clash took place between Borsano and Busto Arsizio. The same document states that: Regarding the identification of the place where the troops of the Lombard League on the run met the remaining part of the
