About two o'clock came a second attack, preceded by a frightful cannonade upon the British left and centre. Four massive columns, led by Ney, poured steadily forward straight for the ridge, sweeping upon and around the farm-stead of La Haye Sainte, but met at every point by the sabres and bayonets of the British lines. Nearly 24,000 men took part in this great movement, the struggle lasting more than an hour before the French staggered back in repulse. Then from the French lines came a stupendous cavalry charge, the massive columns composed of no less than forty squadrons of cuirassiers and dragoons, filling almost all the space between Hougoumont and La Haye Sainte as they poured like a torrent upon the British lines. Torn by artillery, rent by musketry; checked, reformed; charging again, and again driven back; they expended their strength and their lives on the infantry squares that held their ground with the grimmest obstinacy. Once more, now strengthened by the cavalry of the Imperial Guard, they came on to carnage and death, shattering themselves against those unyielding squares, and in the end repulsed with frightful loss. [=Blücher's Prussians and the Charge of Napoleon's Old Guard=] The day was now well advanced, it being half-past four in the afternoon; the British had been fearfully shaken by the furious efforts of the French; when, emerging from the woods at St. Lambert, appeared the head of a column of fresh troops. Who were they? Blücher's Prussians, or Grouchy's pursuing French? On the answer to this question depended the issue of that terrible day. The question was soon decided; they were the Prussians; no sign appeared of the French; the hearts of the British beat high with hope and those of the French sank low in despair, for these fresh troops could not fail to decide the fate of that mighty field of battle. Soon the final struggle came. Napoleon, driven to desperation, launched his grand reserve corps, the far-famed Imperial Guard, upon his enemies. On they come, with Ney at their head; on them pours a terrible torrent of flame; from a distance the front ranks appear stationary, but only because they meet a death-line as they come, and fall in bleeding rows. Then on them, in a wild charge, rush the British Foot Guards, take them in flank, and soon all is over. "The Guard dies, but never surrenders," says their commander. Die they do, few of them surviving to take part in that mad flight which swept Napoleon from the field and closed the fatal day of Waterloo. England has won the great struggle, now twenty years old, and Wellington from that day of victory takes rank with the greatest of British heroes. CHAPTER VI.
