The heads of this extraordinary system were the Committee of Public Safety in Paris and the Representatives on Mission in the Departments. They were the men who created the Terror, and on them the chief responsibility rests. The Committee of Public Safety contained several different groups. Three of its most conspicuous members, who acted closely and consistently together, were Robespierre, Couthon and St. Just. These men were the idealists of the Committee, all fanatical disciples of Rousseau, all aiming at the regeneration of society and determined to secure the triumph of their principles by any means. Robespierre's wide popularity with the Jacobins, his character for respectability and virtue, and his position as the typical exponent of the party creed, made him an indispensable ally, although the more practical among his colleagues regarded his administrative capacities with contempt. Couthon, with his sweet voice and crippled body, and St. Just, with his handsome face and stern demeanour, supported Robespierre's schemes, with the same singular mixture of cruelty and sentiment, of shallow pedantry and deep conviction. But though the triumvirate afterwards grasped at power, and though they all took part in shaping the principles and policy of the Terror, their influence at first was by no means predominant, but was surpassed by that of many of their colleagues. Allied with them in the political work of the Committee, but more effective than they in securing its triumph, were Billaud-Varennes and Collot d'Herbois, the real organisers of the Terror, and among the fiercest of the ruthless men whom that system raised to power. Beside them stood the impressionable Barère, in some respects the most important member of the Government, who represented the Committee in the Convention, where his fluent tongue and easy temper made him popular, and Hérault de Séchelles the least important of the twelve, pre-eminent in courtliness and breeding, but most pre-eminent in society and love. The other five members of the Committee were men whose names with one exception are little known to-day, Lindet and Prieur of the Marne, charged with the work of provisioning the country, Jean Bon St. André, the reorganiser of the navy, and Carnot and Prieur of the Côte-d'Or, the organisers of the great campaigns, which did so much to save the Committee's reputation, and which in the eyes of many Frenchmen have half excused its faults.
