Flight to Varennes
Tronchet had an interesting relationship with Louis XVI. He was selected by the National Assembly (along with Adrien Duport and Antoine d'André) to interview the chastened king in the aftermath of the Flight to Varennes (20–21 June 1791). Eighteen months later, Tronchet was chosen by King Louis XVI as his defense counsel at his trial, and performed this difficult and dangerous task with ability and courage.
