In the third place, while Ney was thus anxiously waiting for Erlon, and seeing the forces in front of him swelling to be more and more superior to his own, there came yet another message from Napoleon telling Ney how matters stood in the great action that was proceeding five miles away, urging him again with the utmost energy to have done at Quatre Bras, to come back over eastward upon the flank of the Prussians at Ligny, and so to destroy their army utterly and "to save France." To have done with the action of Quatre Bras! But there were already superior forces before Ney! And they were increasing! If he dreamt of turning, it would be annihilation for his troops, or at the least the catching of his army's and Napoleon's between two fires. He _might_ just manage when Erlon came up--and surely Erlon must appear from one moment to another--he _might_ just manage to overthrow the enemy in front of him so rapidly as to have time to turn and appear at Ligny before darkness should fall, from three to four hours later. It all hung on Erlon:--He _might_! and at that precise moment, with his impatience strained to breaking-point, and all his expectation turned on Frasnes, whence the head of Erlon's column should appear, there rode up to Ney a general officer, Delcambre by name. He came with a message. It was from Erlon.... Erlon had abandoned the road to Quatre Bras; had understood that he was not to join Ney after all, but to go east and help Napoleon! He had turned off eastward to the right two and a half miles back, and was by this time far off in the direction which would lead him to take part in the battle of Ligny! Under the staggering blow of this news Ney broke into a fury. It meant possibly the annihilation of his body, certainly its defeat. He did two things, both unwise from the point of view of his own battle, and one fatal from the point of view of the whole campaign. First, he launched his reserve cavalry, grossly insufficient in numbers for such a mad attempt, right at the English line, in a despairing effort to pierce such superior numbers by one desperate charge. Secondly, he sent Delcambre back--not calculating distance or time--with peremptory orders to Erlon, as his subordinate, to come back at once to the battlefield of Quatre Bras. There was, as commander to lead that cavalry charge, Kellerman. He had but one brigade of cuirassiers: two regiments of horse against 25,000 men! It was an amazing ride, but it could accomplish nothing of purport. It thundered down the slope, breaking through the advancing English troops (confused by a mistaken order, and not yet formed in square), cut to pieces the gunners of a battery, broke a regiment of Brunswickers near the top of the hill, and reached at last the cross-roads of Quatre Bras. Five hundred men still sat their horses as the summit of the slope was reached. The brigade had cut a lane right through the mass of the defence; it had not pierced it altogether.
