[100] The insurrectionists followed a decided and pre-conceived plan. The barricades, which intersected the streets of Paris in every direction, were arranged on a general system which showed considerable skill. Was this ensemble a conception of Cluseret? or a plan of Gaillard, or Eudes, or Rossel? No one now could say which, but at any rate we are able to deduce the plan from the facts and set it out as follows:— Within the line of the fortifications the insurgents had formed a second line of defence, which runs on the right bank of the river, by the Trocadero, the Triumphal Arch, the Boulevard de Courcelles, the Boulevard de Batignolles, and the Boulevard de Rochechouart; and on the left across the bridge of Iéna, the Avenue de la Bourdonnaye, the École Militaire, the Boulevard des Invalides, the Boulevard Montparnasse, and the Western Railway Station. Along the whole extent of this circuit the entrances of the streets were barricades, and the “Places” turned into redoubts. From this double _enceinte_ of fortifications the lines of defence converged along the great boulevards, the Rue Royale, by the Ministry of Marine, the terrace of the Tuileries Gardens, the Place de la Concorde, the Palace of the Corps Législatif, the Rue de Bourgogne, and the Rue de Varenne. This third _enceinte_ of defence was the pride of the insurgents; they were never tired of admiring their celebrated barricade of the Rue St. Florentin, and that which intercepted the quay at the corner of the Tuileries Gardens on the Place de la Concorde. This is not all. Supposing that the third line were forced, the insurgents would not even then be without resource. On the left bank of the Seine they fell back successively on the Rue de Grenelle, Rue Saint Dominique, and Rue de Lille, all three closed by barricades; on the right bank they could carry on the struggle by the Rue Neuve-des-Petits-Champs, the Rue de la Paix, and the Place Vendôme, and even when beaten back from these last retreats, they could still defend the Rue St. Honoré and operate a retreat by the Palace of the Tuileries, the Louvre, and the Hôtel de Ville.
