Louis sent small expeditions one after one to Italy at the beginning of his war against Joanna, because he did not want to harass the Italians who had suffered from a famine the previous year. His first troops departed under the command of Nicholas Vásári, Bishop of Nyitra (now Nitra in Slovakia), on 24 April 1347. Louis also hired German mercenaries. He departed from Visegrád on 11 November. After marching through Udine, Verona, Modena, Bologna, Urbino, and Perugia, he entered the Kingdom of Naples on 24 December near L'Aquila, which had yielded to him.
