Intoxicated with these victories, the Convention abandoned itself to the fervour of propaganda and conquest. The river Scheldt had been closed to commerce by various treaties to which England and Holland, neutral powers, were parties. Without a pretence of negotiation the French government declared on the 16th of November that the Scheldt was thenceforwards open. On the 19th a decree of the Convention offered the aid of France to all nations which were striving after freedom--in other words, to the malcontents in every neighbouring state. Not long afterwards the Convention annexed Savoy, with the consent, it should be added, of many Savoyards. On the 15th of December the Convention decreed that all peoples freed by its assistance should carry out a revolution like that which had been made in France on pain of being treated as enemies. Towards Great Britain the executive council and the Convention behaved with singular folly. There, in spite of a growing antipathy to the Revolution, Pitt earnestly desired to maintain peace. The conquest of the Netherlands and the symptoms of a wish to annex that country made his task most difficult. But the French government underrated the strength of Great Britain, imagining that all Englishmen who desired parliamentary reform desired revolution, and that a few democratic societies represented the nation. When Monge announced the intention of attacking Great Britain on behalf of the English republicans, the British government and nation were thoroughly alarmed and roused; and when the news of the execution of Louis XVI. was received, Chauvelin, the French envoy, was ordered to quit England. France declared war against England and Holland on the 1st of February and soon afterwards against Spain. In the course of the year 1793 the Empire, the kings of Portugal and Naples and the grand-duke of Tuscany declared war against France. Thus was formed the first coalition.
