On May 16, 1423 Charles VII charged de Brosse with ensuring his safety. Then on July 14, 1426, de Brosse was made a Marshal of France. He fought the English and their allies at the side of La Hire, Jean de Dunois, Jean Poton de Xaintrailles, and Arthur de Richemont. He soon began growing short of money, however, due to work on the castle of Boussac and the cost of his army. The French government was unable to compensate de Brosse for his service, being short on money themselves. He resorted to selling off his crockery, silver, and his wife’s jewelry. He also freed the inhabitants of Boussac from his rule, in exchange for money.
