Their adversaries skilfully turned this circumstance to advantage. They secretly circulated a report which could not but compromise the Girondists; it was, that they wished to remove the republic to the south, and give up the rest of the empire. Then commenced that reproach of federalism, which afterwards became so fatal. The Girondists disdained it because they did not see the consequences; but it necessarily gained credit in proportion as they became weak and their enemies became daring. What had given rise to the report was the project of defending themselves behind the Loire, and removing the government to the south, if the north should be invaded and Paris taken, and the predilection they manifested for the provinces, and their indignation against the agitators of the capital. Nothing is more easy than to change the appearance of a measure by changing the period in which the measure was adopted, and discover in the disapprobation expressed at the irregular acts of a city, an intention to form the other cities of the state into a league against it. Accordingly, the Girondists were pointed out to the multitude as federalists. While they denounced the commune, and accused Robespierre and Marat, the Mountain decreed _the unity and indivisibility of the republic_. This was a way of attacking them and bringing them into suspicion, although they themselves adhered so eagerly to these propositions that they seemed to regret not having made them.
But a circumstance, apparently unconnected with the disputes of these two parties, served still better the cause of the Mountain. Already emboldened by the unsuccessful attempts which had been directed against them, they only waited for an opportunity to become assailants in their turn. The convention was fatigued by these long discussions. Those members who were not interested in them, and even those of the two parties who were not in the first rank, felt the need of concord, and wished to see men occupy themselves with the republic. There was an apparent truce, and the attention of the assembly was directed for a moment to the new constitution, which the Mountain caused it to abandon, in order to decide on the fate of the fallen prince. The leaders of the extreme Left were driven to this course by several motives: they did not want the Girondists, and the moderate members of the Plain, who directed the committee of the constitution, the former by Pétion, Condorcet, Brissot, Vergniaud, Gensonné, the others by Barrère, Sieyès, and Thomas Paine, to organize the republic. They would have established the system of the bourgeoisie, rendering it a little more democratic than that of 1791, while they themselves aspired at constituting the people. But they could only accomplish their end by power, and they could only obtain power by protracting the revolutionary state in France. Besides the necessity of preventing the establishment of legal order by a terrible coup d'état, such as the condemnation of Louis XVI., which would arouse all passions, rally round them the violent parties, by proving them to be the inflexible guardians of the republic, they hoped to expose the sentiments of the Girondists, who did not conceal their desire to save Louis XVI., and thus ruin them in the estimation of the multitude. There were, without a doubt, in this conjuncture, a great number of the Mountain, who, on this occasion, acted with the greatest sincerity and only as republicans, in whose eyes Louis XVI. appeared guilty with respect to the revolution; and a dethroned king was dangerous to a young democracy. But this party would have been more clement, had it not had to ruin the Gironde at the same time with Louis XVI.
