Jacques de GRAVEL, Abbot of Argentan, diplomat, extraordinary envoy to the Electors of Trier and Mainz. L.S., Würzburg, January 26, 1669, [to the Elector Palatine]; 2 folio pages (tab mark). Marshal de Créquy, believing himself to be near Heidelberg, decided to entrust the abbot “with the mission he assigns to me in a letter I have received from him […] or Your Electoral Highness will better understand his sentiments than through any expression I might have attempted on my own.” He offers his services to the Elector through the marshal, “having no doubt that Your Highness has shorter and more convenient channels than mine for making your wishes known to him”… [This concerns the demobilization of troops following the War of Devolution.]
