Abstract EN:

In 1791, Calonne, disappointed fy foreign powers, favoured the creation of armed forces. One of them, formed of émigrés and mercenaries in order to invade France on its eastern frontier, consisted of three armies in 1791-1792, under the orders of Mirabeau-Tonneau, Condé and the Princes. Another one, which was to be the result of the coalition of the marquis de la Roue͏̈rie, was supposed to be a legion of more than 4000 men, raised in Brittany, who would be equipped and paid. The task of this legion would be, on the one hand, to stifle any sign of civil war in the province when the invasion of the émigré army took place and, on the other hand, to create a powerful diversion in western France so as to second the offensive of the latter. Prussia went to war, which considerably reinforced the eastern front. But La Roue͏̈rie failed in his attempt to set up a legion, which became obvious to all those who attented the meeting held on May 27th 1792 in order to assess the strength of their forces. Nevertheless, until October 11th, he obstinately maintained his intention to mobilize his partisans. The coalition of La Roue͏̈rie is the subject-matter of this work. At the beginning, it deals with La Roue͏̈rie's plan and its result, and the causes of its failure are touched upon. After May 27th, it is only a matter of factual history which is not however entirely devoid of interest as it must be taken into account when studying Valmy and as it throws some light on the attitude of Danton before August 10th 1792 and then until his negociation with Brunswyck after September 20th.
