In 1832 Marshal Bourmont took part in the rising of Caroline Ferdinande Louise, duchesse de Berry and on its failure fled to Portugal. He commanded the army of the absolutist monarch King Miguel during the Liberal Wars and after the victory of the constitutional party he retired to Rome. At the amnesty of 1840 he returned to France, where he died on 27 October 1846 at Freigné in Maine-et-Loire.
