At five in the morning Davout marched from Raigern, and about nine joined Legrand to engage the enemy's left. Meantime, at a quarter to eight, Soult began to climb the Pratzen slopes with the divisions of Vandamme and Saint-Hilaire. In about twenty minutes--the exact time in which he had declared he could do so--he had made good his position, and was fiercely engaged with the column of Kollowrath, which formed the enemy's center, and with which Kutusoff was present in person. The latter, realizing for the first time what the loss of Pratzen would mean, endeavored to concentrate toward the right; but his efforts were unavailing: he could only stand and fight. The two Austro-Russian columns on his left swooped down to the Goldbach, and seized both Telnitz and Sokolnitz. Simultaneously with Soult's advance, Bernadotte and Murat moved forward, encountering between Girzikowitz and Blasowitz the enemy's cavalry under Prince Lichtenstein, and the Russian imperial guard under the Grand Duke Constantine. (p.~387) Napoleon advanced to observe the conflict, and a little before eleven, at the critical moment, when the regiment of his brother Joseph was on the verge of being engulfed and lost, he threw in the cavalry of his own guard, under Bessières and Rapp, upon the Russian guard, turned the scale against them, and with his own eyes saw Constantine withdraw. The Russian vanguard under Bagration had meantime come in from Bosenitz, and was hotly engaged with a portion of the French left. The entire cavalry mass of Lichtenstein and Murat was commingled in bitter conflict. With the retreat of Constantine began the rout of the whole Austro-Russian right wing. Lannes, supported by the Santon redoubt, had stood like a rock until then; at once he precipitated himself, with the divisions of Suchet and Caffarelli, upon Bagration, and drove him back. Lichtenstein, who, up to that moment, had at least held his own,--if, indeed, he had not shown himself the stronger,--could no longer stand, and late in the afternoon he too began to yield.
