Charles Armand Tuffin, marquis de la Rouërie[1] (13 April 1751 – 30 January 1793) was a French military officer and nobleman who served during the American Revolutionary War.

La Rouërie is less-remembered than Gilbert du Motier, Marquis de Lafayette and other Frenchmen in writings on France in the American Revolutionary War.

Destined for a military career from his earliest years, La Rouërie had an impetuous temperament that soon brought him to the public eye.

Promoted to a General on 25 June 1778, La Rouërie took part in the battles of New York, Monmouth, Short Hills, Brandywine, Whitemarsh, the Campaign in Virginia, and the Siege of Yorktown.

[2] In the time leading to the French Revolution, La Rouërie declared himself a champion of the nobility and parliament of Brittany, which was struggling against the central court at Versailles.

[2] In 1788 he gave up his military career when he rejected a command offered by Louis XVI, out of opposition to the king's suppression of liberties which the kingdom of France had accorded Brittany on their union, and was imprisoned as a result in the Bastille on 14 July that year.

Excited to resistance, he provoked a refusal to send representatives to the Estates General, saying that he did not want those of the ancient nobility to bend over themselves to become a double representation of the people.

[14] La Rouërie found support among the population of Brittany, who were very disappointed with the results of the Revolution, after having first been in favor, and then strongly opposed to the Civil Constitution of the Clergy, which sought to destroy the independence of the Catholic Church in France from control by the State.

La Rouërie, a non practicing Catholic[15] criticized the Civil Constitution of the Clergy, and prepared the manifesto of the Breton Association.

[18] After a raid by French Revolutionary Army dragoons upon the Marquis's castle, La Rouërie moved to Launay-Villiers, which was located close to the hideout of Jean Chouan and his men.

Alerted by a neighbor, La Guyomar hid the marquis in a farm, located a hundred meters from the castle.

La Rouërie, however, asked to read the newspaper for news of the kings trial as he sensed his servant Saint Pierre.

[23] In a crisis of delirium, La Rouërie jumped out of bed, dressed, with the intent to leave the castle, but collapsed in a fit of weakness.
