Every one now knows, that at nightfall between seven and eight o'clock the Emperor, having discovered that the column which had been signalled in our rear was the corps of General d'Erlon, which had missed its route between the battle of Ney with the English at Quatre-Bras and ours here at Ligny, had ordered the Old Guard to support us at once. The lieutenant who was with us said, "This is the grand attack. Attention!" The whole of the Prussian cavalry was swarming between the two villages. We felt that there was a grand movement behind us, though we did not see it. The lieutenant repeated, "Attention to orders! Let no one stay behind after the order to march! Here is the attack!" We all opened our eyes. The farther the night advanced the redder the sky grew over St. Amand. We were so absorbed in listening to the cannonade that, we no longer thought of anything else. At each discharge you would have said the heavens were on fire. The tumult behind us was increasing. Suddenly the broad street running along the brook was full of troops, from the bridge quite to the end of Ligny. On the left in the distance the Prussians were shooting from the windows again, while we did not reply. The shout rose--"The Guard! the Guard!" I do not know how that mass of men passed the muddy ditch, probably by means of plank thrown across, but in a moment they were on the left bank in force. The batteries of the Prussians at the top of the ravine between the two villages, cut gaps through our columns, but they closed up immediately, and moved steadily up the hill. What remained of our division ran across the bridge, followed by the artillerymen and their pieces with the horses at a gallop. Then we went down to the street, but we had not reached the bridge when the cuirassiers began to file over it, followed by the dragoons and the mounted grenadiers of the guard. They were passing everywhere, across and around the village. It was like a new and innumerable army. The slaughter began again on the hill, this time the battle was in the open fields, and we could trace the outlines of the Prussian squares on the hill-side at every discharge of musketry. We rushed on over the dead and wounded, and when we were clear of the village we could see that there was an engagement between the cavalry, though we could only distinguish the white cuirasses as they pierced the lines of the Uhlans; then they would be indiscriminately mingled and the cuirassiers would re-form and set off again like a solid wall.
