In his letters, Charles-Joseph, 7th Prince of Ligne, wrote to his friend Louis Philippe, comte de Ségur while serving with the army at the 1788 Siege of Ochakov. He described "a Frenchman of three ages - the chivalry of one, the grace of another, and the gayety of the present day". The Prince continued, "He is as giddy as a bumblebee in the midst of the liveliest cannonading". He noted a weakness, "Always French in soul, and it may be, a trifle vain." De Ligne concluded with, "Amiable, beloved by all, and what one calls a charming fellow, a brave fellow, a seigneur of the good tone of the Court of France - that is what Roger Damas is". Damas served with Archduke Charles, Duke of Teschen at the Siege of Izmail in 1791.
