Louis's expedition counted to some 40,000 troops, including those of Amadeus VI of Savoy, and had the financial support of Antipope Clement VII and Bernabò Visconti of Milan. Charles, who counted on the mercenary companies under John Hawkwood and Bartolomeo d'Alviano, for a total of some 14,000 men, was able to divert the French from Naples to other regions of the kingdom and to harass them with guerrilla tactics. Amadeus fell ill and died in Molise on 1 March 1383, and his troops abandoned the field. Louis asked for help to his king in France, who sent him an army under Enguerrand VII, Lord of Coucy. The latter was able to conquer Arezzo and then invade the Kingdom of Naples, but midway was reached by the news that Louis had suddenly died at Bisceglie on 20 September 1384.
