Dumouriez was forty-seven years of age when the revolution began; he had lived till then immersed in intrigue, and he retained his old habits too closely at an epoch when he should have employed small means only to aid great ones, instead of supplying their place. The first part of his political life was spent in seeking those by whom he might rise: the second, those by whom he might maintain his position. A courtier up to 1789, a constitutionalist under the first assembly, a Girondist under the second, a Jacobin under the republic, he was eminently a man of circumstances. But he had all the resources of great men; an enterprising character, indefatigable activity, a ready, sure, and extensive perception, impetuosity of action, and an extraordinary confidence of success; he was, moreover, open, easy, witty, daring; adapted alike for arms and for factions, full of expedients, wonderfully ready, and, in difficult positions, versed in the art of stooping to conquer. It is true that his great qualities were weakened by defects; he was rash, flighty, full of inconsistency of thought and action, owing to his continual thirst for movement and machination. But his great defect was the total absence of a political conviction. In times of revolution, nothing can be done for liberty or power by him who is not decidedly of one party or another, and when he is ambitious, unless he see further than the immediate objects of that party, and have a stronger will than his colleagues. This it was made Cromwell; this it was made Buonaparte; while Dumouriez, the employed of all parties, thought he could get the better of them all by intriguing. He wanted the passion of his time: that which completes a man, and alone enables him to sway.
Roland was the opposite of Dumouriez; his was a character which Liberty found ready formed, as if moulded by herself. Roland had simple manners, austere morals, tried opinions; enthusiastically attached to liberty, he was capable of disinterestedly devoting to her cause his whole life, or of perishing for her, without ostentation and without regret. A man worthy of being born in a republic, but out of place in a revolution, and ill adapted for the agitation and struggle of parties; his talents were not superior, his temper somewhat uncompliant; he was unskilled in the knowledge and management of men; and though laborious, well informed, and active, he would have produced little effect but for his wife. All he wanted she had for him; force, ability, elevation, foresight. Madame Roland was the soul of the Gironde; it was at her house that those brilliant and courageous men assembled to discuss the necessities and dangers of their country; it was she who stimulated to action those whom she saw were qualified for action, and who encouraged to the tribune those whom she knew to be eloquent.
