but this was reversed in 1313. The Riga lawsuit was finally decided in the Teutonic Order's favor by Clement's successor John XXII after a hearing in Avignon in 1319. Under Władysław Łokietek and his successor Casimir III the Great an additional two lawsuits were filed against the order at the curia, both aiming at the return of Pomerelia. The sites of investigation were Inowrocław and Brześć Kujawski in 1320/21 and Warsaw in 1339. The judges were Domarat, bishop of Poznań, Janisław, archbishop of Gniezno and, Nikolaus (Mikolaj), abbot of Mogilno in the first case and Galhard of Chartres and Peter (Pierre) of Gervais in the second case. Witness and eyewitness reports collected during these cases include mentions of killings during the takeover of Danzig, referred to e.g. as strage magna or maxima (great (est) murder/bloodbath), while the Teutonic Order admitted the killing of 15 to 16 Pomerelian knights. The testimonies from the lawsuits and the order's responses are the primary sources used by historians to reconstruct the events. The lawsuits did not have any practical effect on the order, who won both cases by appeal. In the 15th century, era of the Polish-Teutonic Wars, medieval Polish chronicler Jan Długosz in epic prose described the event as a slaughter of Polish nationals, regardless of condition, age or sex. Modern sources are divided as to the actual extent of the massacre though they all agree that mass killings did take place. Historian Matthew Kuefler states: "German and Polish historians in the twentieth century tended to have diverging [views] both on the question of whether Pomerelia really "belonged" to Poland and also on the degree of ferocity of the order's conquest". The city of Gdańsk states that "The Teutonic Knights, having captured the castle in 1308 butchered the population. Since then the event is known as the Gdańsk slaughter". In many Polish works, the takeover is referred to as "Gdańsk slaughter" (rzeź Gdańska). Norman Davies in his extensive history of Poland, while not insisting on the number of 10,000 dead, says that the knights "drove Waldemar from the city, and calmly slaughtered its inhabitants", similar descriptions are presented also in some other English books with sections on Polish history. Jerzy Lukowski in "A concise history of Poland" says that the knights massacred "Lokietek's men". Błażej Śliwiński says that there was a bloodbath which cost an abundance of lives, though not 10,000, and that
