felt a respectful sympathy for their ecclesiastical neighbours, and foresaw that in a system of annexation their own turn would come next. The principle of secularisation was accepted by the Congress without much difficulty, all the energy of debate being reserved for the discussion of details: arrangements which were to transfer a few miles of ground and half a dozen custom-houses from some bankrupt ecclesiastic to some French-bought duke excited more interest in Germany than the loss of the Rhenish Provinces, and the subjection of a tenth part of the German nation to a foreign rule. [Austria determines on war, 1798.] One more question was unexpectedly presented to the Congress. After proclaiming for six years that the Rhine was the natural boundary of France, the French Government discovered that a river cannot be a military frontier at all. Of what service, urged the French plenipotentiaries, were Strasburg and Mainz, so long as they were commanded by the guns on the opposite bank? If the Rhine was to be of any use to France, France must be put in possession of the fortresses of Kehl and Castel upon the German side. Outrageous as such a demand appears, it found supporters among the venal politicians of the smaller Courts, and furnished the Committee with material for arguments that extended over four months. But the policy of Austria was now taking a direction that rendered the resolutions of the Congress of very little importance. It had become clear that France was inclining to an alliance with Prussia, and that the Bavarian annexations promised to Austria by the secret articles of Campo Formio were to be withheld. Once convinced, by the failure of a private negotiation in Alsace, that the French would neither be content with their gains of 1797, nor permit Austria to extend its territory in Italy, Thugut determined upon a renewal of the war. [63] In spite of a powerful opposition at Court, Thugut's stubborn will still controlled the fortune of Austria: and the aggressions of the French Republic in Switzerland and the Papal States, at the moment when it was dictating terms of peace to the Empire, gave only too much cause for the formation of a new European league.
