It was not eight o’clock. The guns, which were thundering more fiercely than ever in the direction of Bazeilles, now also began to make themselves heard at the eastward, in the valley of la Givonne, which was hid from view; it was the army of the Crown Prince of Saxony, debouching from the Chevalier wood and attacking the 1st corps, in front of Daigny village; and now that the XIth Prussian corps, moving on Floing, had opened fire on General Douay’s troops, the investment was complete at every point of the great periphery of several leagues’ extent, and the action was general all along the line. Maurice suddenly perceived the enormity of their blunder in not retreating on Mézières during the night; but as yet the consequences were not clear to him; he could not foresee all the disaster that was to result from that fatal error of judgment. Moved by some indefinable instinct of danger, he looked with apprehension on the adjacent heights that commanded the plateau de l’Algérie. If time had not been allowed them to make good their retreat, why had they not backed up against the frontier and occupied those heights of Illy and Saint-Menges, whence, if they could not maintain their position, they would at least have been free to cross over into Belgium? There were two points that appeared to him especially threatening, the _mamelon_ of Hattoy, to the north of Floing on the left, and the Calvary of Illy, a stone cross with a linden tree on either side, the highest bit of ground in the surrounding country, to the right. General Douay was keenly alive to the importance of these eminences, and the day before had sent two battalions to occupy Hattoy; but the men, feeling that they were “in the air” and too remote from support, had fallen back early that morning. It was understood that the left wing of the 1st corps was to take care of the Calvary of Illy. The wide expanse of naked country between Sedan and the Ardennes forest was intersected by deep ravines, and the key of the position was manifestly there, in the shadow of that cross and the two lindens, whence their guns might sweep the fields in every direction for a long distance. Two more cannon shots rang out, quickly succeeded by a salvo; they detected the bluish smoke rising from the underbrush of a low hill to the left of Saint-Menges. “Our turn is coming now,” said Jean.
