But La Fayette was determined not to relinquish the constitution he had formed, and, in spite of the unpopularity of the royal dignity, rendered more so by this frustrated attempt to escape, he was resolved to uphold it; and was joined in this purpose by Barnave and others, who did not always share his sentiments, but who thought it shame, apparently, to show to the world, that a constitution, framed for immortality upon the best political principles of the most accomplished statesmen in France, was so slightly built, as to part and go asunder at the first shock. The purpose of the commandant of Paris, however, was not to be accomplished without a victory over the united strength of the Republican and Jacobinical parties, who on their part might be expected to put in motion on the occasion their many-handed revolutionary engine, an insurrection of the people. Such was the state of political opinions, when the unfortunate Louis was brought back to Paris.[152] He was, with his wife and children, covered with dust, dejected with sorrow, and exhausted with fatigue. The faithful gardes du corps who had accompanied their flight, sate bound like felons on the driving seat of the carriage. His progress was at first silent and unhonoured. The guard did not present arms--the people remained covered--no man said God bless him. At another part of the route, a number of the rabble precipitated themselves on the carriage, and it was with the utmost difficulty that the national guards and some deputies, could assure it a safe passage.[153] Under such auspices were the royal family committed once more to their old prison of the Tuileries. Meantime the crisis of the King's fate seemed to be approaching. It was not long ere the political parties had an opportunity of trying their respective force. A meeting was held, upon the motion of the Republican and Jacobinical leaders, in the Champ de Mars, [July 17,] to subscribe a petition[154] for the dethronement of the King, couched in the boldest and broadest terms. There was in this plain a wooden edifice raised on scaffolding, called the Altar of the Country, which had been erected for the ceremony of the Federation of 14th July, 1790, when the assembled representatives of the various departments of France took their oath to observe the constitution. On this altar the petition was displayed for signature; but each revolutionary act required a preliminary libation of blood, and the victims on this occasion were two wretched invalids, whom the rabble found at breakfast under the scaffolding which supported the revolutionary altar, and accused of a design to blow up the patriots. To accuse was to condemn. They were murdered without mercy, and their heads paraded on pikes, became as usual the standards of the insurgent citizens.[155] [Sidenote: REVOLT IN THE CHAMP DE MARS.]
