The victory of Jemappes, the first pitched battle won by the Republic, excited an outburst of revolutionary fervour in the Convention which deeply affected the relations of France to Great Britain, hitherto a neutral spectator of the war. A manifesto was published declaring that the French nation offered its alliance to all peoples who wished to recover their freedom, and charging the generals of the Republic to give their protection to all persons who might suffer in the cause of liberty (Nov. 19). A week later Savoy and Nice were annexed to France, the population of Savoy having declared in favour of France and Sardinia. On the 15th of December the Convention proclaimed that social and political revolution was henceforth to accompany every movement of its armies on foreign soil. "In every country that shall be occupied by the armies of the French Republic"--such was the substance of the Decree of December 15th--"the generals shall announce the abolition of all existing authorities; of nobility, of serfage, of every feudal right and every monopoly; they shall proclaim the sovereignty of the people, and convoke the inhabitants in assemblies to form a provisional Government, to which no officer of a former Government, no noble, nor any member of the former privileged corporations shall be eligible. They shall place under the charge of the French Republic all property belonging to the Sovereign or his adherents, and the property of every civil or religious corporation. The French nation will treat as enemies any people which, refusing liberty and equality, desires to preserve its prince and privileged castes, or to make any accommodation with them."
