Disapproving of how the Revolution was developing, he resigned as a deputy on 8 July 1791, emigrated and became a captain in the régiment de Dillon, a French Royalist unit fighting alongside the British. He returned to France under the First French Empire and remained in retirement at Belleau until his death.
