The Russians were the assailants, making a combined movement on Ney's division, which was stationed at Gutstadt, and in the vicinity. They pursued him as far as Deppen, where there was some fighting; but upon the 8th of June, Napoleon advanced in person to extricate his marshal, and Bennigsen was obliged to retreat in his turn. He was hardly pressed on the rear by the Grand Army of France. But even in this moment of peril, Platow, with his Cossacks, made a charge, or, in their phrase, a hourra, upon the French, with such success, that they not only dispersed the skirmishers of the French vanguard, and the advanced troops destined to support them, but compelled the infantry to form squares, endangered the personal safety of Napoleon, and occupied the attention of the whole French cavalry, who bore down on them at full speed. Musketry and artillery were all turned on them at once, but to little or no purpose; for, having once gained the purpose of checking the advance, which was all they aimed at, the cloud of Cossacks dispersed over the field, like mist before the sun, and united behind the battalions whom their demonstration had protected. By this means Platow and his followers had got before the retreating division of the Russian army under Bagration, which they were expected to support, and had reached first a bridge over the Aller. The Cossacks were alarmed by the immense display of force demonstrated against them, and showed a disposition to throw themselves confusedly on the bridge, which must certainly have been attended with the most disastrous consequences to the rear-guard, who would thus have been impeded in their retreat by the very troops appointed to support them. The courage and devotion of Platow prevented that great misfortune. He threw himself from his horse. "Let the Cossack that is base enough," he exclaimed, "desert his Hettman!" The children of the wilderness halted around him, and he disposed them in perfect order to protect the retreat of Bagration and the rear-guard, and afterwards achieved his own retreat with trifling loss.[274] [Sidenote: ACTION OF HEILSBERG.]
