Robert Parker, who fought against the Jacobites at Aughrim, described Saint-Ruhe as "a gallant, brave man, and a good officer". The soldier and diplomat Saint-Simon, in his "Memoirs", painted a less flattering portrait. This should be treated with some caution as he was only sixteen when Saint-Ruhe died, though he did apparently meet him. He described him as a "gentleman in a small way", tall and well built but exceptionally ugly; a gallant soldier but notorious for domestic cruelty. According to Saint-Simon, Saint-Ruhe's treatment of his wife became so brutal that she eventually asked the King to intervene. Louis treated her with great sympathy and ordered her husband to stop, but when the ill-treatment continued the King began sending him on unnecessary missions to free his wife of his company.
