were regions that became depopulated in 1349, and the demand for work force increased in the subsequent years. Louis proposed to renounce the Kingdom of Naples if Clement dethroned Joanna. After the pope refused, Louis departed for his second Neapolitan campaign in April 1350. He suppressed a mutiny that occurred among his mercenaries while he and his troops were waiting for the arrival of further troops in Barletta. While marching towards Naples, he faced resistance at many towns because his vanguards, which were under the command of Stephen Lackfi, had become notorious for their cruelty. During the campaign, Louis personally led assaults and climbed city walls together with his soldiers, endangering his own life.

The two monarchs agreed that Halych and Lodomeria would be integrated into the Kingdom of Hungary after Casimir's death. Casimir also authorized Louis to redeem the two realms for 100,000 florins if Casimir fathered a son. Louis led his army to Cracow in June 1351. Because Casimir fell ill, Louis became the sole commander of the united
