During the Seven Years' War he was taken prisoner and exchanged at the Battle of Rossbach in 1757, and fought against Prussia in Corbach and Kassel. On September 7, 1759, the Marquis signed a military treaty known later as the \"Convention of Brandebourg\". This agreement, concluded with the representative of the Prussian armies, General Major Baron Buddenbrock, stipulated that the hospitals, wounded soldiers and lazarets as well as the medical personnel would not be considered as fighting units. A century later Henry Dunant, founder of the Red Cross, described this as the first \"Red Cross treaty\" when he requested funds from the Emperor Napoleon III. The Marquis was struck down in 1761 at the Battle of Villinghausen, where he was fatally wounded. The Marquess of Granby, in a letter, reported that the Marquis de Roug\u00E9 was talking with his cousin, the Duc de Croy d\u2019Havr\u00E9e (of the House of Cro\u00FF), his brother-in-law Lieutenant General the Marquis de Verac, and his cousin Lieutenant General Count de Roug\u00E9 (the Duke de Croy d'Havr\u00E9's son-in-law) when a cannonball struck the group, killing three of them and taking off the leg of the Marquis de Roug\u00E9. His portrait is in the Galerie des Batailles at Versailles."@en . . . . . . . . . . . "1707"^^ . . . "Pierre-Fran\u00E7ois, Marquess of Roug\u00E9"@en .
