The battle of Kulm was lost by the French through the negligence of Vandamme, who omitted to occupy the defiles in his rear--an extraordinary blunder, for which a far younger soldier might well be blamed. The triumph was complete, and, in conjunction with those at the Katzbach and Gross-Beeren, greatly raised the spirits of the Allies. At Kulm, the French fought, as usual, most gallantly, but for once they were outmanoeuvred. A brilliant exploit of three or four hundred chasseurs, belonging to Corbineau's light cavalry division, is worthy of mention. Sabre in hand, they cut their way completely through Kleist's corps, and did immense injury to the Allies, especially to the artillery. Of themselves, few, if any, escaped alive. "Not only," says Baron Von Rahden, "did they ride down several battalions at the lower end of the defile, and cut to pieces and scatter to the winds the staff and escort of the general, which were halted upon the road, but they totally annihilated our artillery for the time, inasmuch as they threw the guns into the ditches, and killed nearly all the men and horses. By this example one sees what resolute men on horseback, with good swords in their hands, and bold hearts in their bosoms, are able to accomplish." In a letter of Prince Augustus of Prussia, we find that "the artillery suffered so great a loss at Kulm, that there are still (this was written in the middle of September, fifteen days after the action) eighteen officers, eighty non-commissioned officers, one hundred and twenty-six bombardiers, seven hundred and eighteen gunners, besides bandsmen and surgeons, wanting to complete the strength." In both days' fight the present King of the Belgians greatly distinguished himself. He was then in the Russian service, and, on the 29th, fought bravely at the head of his cavalry division. On the 30th, the Emperor Alexander sent him to bring up the Austrian cavalry reserves, and the judgment with which he performed this duty was productive of the happiest results.
