The old Russian general, when he learned the French Emperor's plan of retiring by Gjatz and Wiazma, instantly turning his own retreat into a movement to the left, arrived by cross-roads from Malo-Yarowslavetz. The Russians now reached the point of action at daybreak, pushed through Prince Eugene's line of march, and insulated his vanguard, while the Cossacks rode like a whirlwind among the host of stragglers and followers of the army, and drove them along the plain at the lance's point. The viceroy was succoured by a regiment which Ney, though himself hardly pressed, despatched to his aid from Wiazma, and his rear-guard was disengaged by the exertions of Davoust, who marched hastily forward to extricate them. The Russian artillery, which is superior in calibre, and carries farther than the French, manœuvred with rapidity, and kept up a tremendous cannonade, to which the French had no adequate means of replying. Eugene and Davoust made a most gallant defence; yet they would not have been able to maintain their ground, had Koutousoff, as was to have been expected, either come up in person, or sent a strong detachment to support his vanguard. The battle lasted from seven in the morning till towards evening, when Eugene and Davoust pushed through Wiazma with the remains of their divisions, pursued by and almost mingled with the Russians, whose army marched into the town at the charging step, with drums beating, and all the indications of victory. The French divisions, under cover of the night, and having passed the river (which, like the town, is called Wiazma,) established themselves in obscurity and comparative safety upon the left bank. The day had been disastrous to the French arms, though their honour remained unsullied. They had lost about 4000 men, their regiments were mouldered down to battalions, their battalions to companies, their companies to weak picquets.[199]
