Question: Besides the Army of Conde, what were the other emigre field armies during the French Revolutionary War? Passage:The Army of Conde () was a French field army during the French Revolutionary Wars. One of several emigre field armies, it was the only one to survive the War of the First Coalition; others had been formed by the Comte d'Artois (brother of King Louis XVI) and Mirabeau-Tonneau. The emigre armies were formed by aristocrats and nobles who had fled from the violence in France after the August Decrees. The army was commanded by Louis Joseph de Bourbon, Prince de Conde, the cousin of Louis XVI of France. Among its members were Conde's grandson, the Duc d'Enghien and the two sons of Louis XVI's younger brother, the Comte d'Artois, and so the army was sometimes also called the Princes' Army.
