In 1390, Jean claimed the Kingdom of Majorca, but was overcome by the troops of John I of Aragon in a battle near Navata. John consequently led military actions in Roussillon.

In 1391, he had to leave for Italy in order to go to the assistance of Charles Visconti, Lord of Parma and husband of his sister, Beatrice of Armagnac. Visconti was in conflict with his acquisitive cousin Gian Galeazzo Visconti, later the duke of Milan, whose ambition was to control the whole of northern Italy.

His army was attacked and decisively beaten by that of Gian Galeazzo Visconti as it passed through Alessandria in Piedmont.^[2] John was killed in the battle.^[2][3]
