[Illustration: THE FIRST BATTLE OF POLOTSK Gained by General St. Cyr (in succession to Marshal Oudinot wounded) on 18th August, 1812] For some reason which is not very apparent the infantry attack did not take place immediately. Possibly St. Cyr hoped that the fire of his 130 guns or thereabouts would soon demoralise the Russians, but he was deceived. Wittgenstein’s troops fell quickly into their places in the line, and their artillery stoutly responded to the greatly superior mass of Franco-Bavarian batteries. After a cannonade of about an hour’s duration, Wrede moved forward, threatening to turn the Russian left, while Deroy marched straight against Prizmenitza. Legrand’s division, however, moved forward rather slowly, and Verdier’s division (temporarily commanded by General of Brigade Valentin) was still farther to the rear. The result was that the Russian resistance was by no means crushed by the impetus of a combined charge. As the Bavarians advanced they screened the fire of their guns, and the Russian artillery was able to play heavily upon the infantry. Deroy, a venerable officer respected by all, was mortally wounded as he directed his division, and the Bavarians, shaken by their losses, began to give way. Legrand, now in line on their left, carried Prizmenitza, but was driven out again by Hamen with seven battalions of Sazonov’s division. St. Cyr himself hastened to the front and directed a fresh advance of Legrand against Prizmenitza, supported by Sieben’s brigade of Deroy’s division. Wrede was directed to assume the command of the whole 6th Corps, and himself rallied and led on Deroy’s shaken troops. The four French and Bavarian infantry divisions, now supported by Merle on the left rear, moved forward together, breaking down the obstinate resistance of the Russians and forcing them back into the woods. The Russian cavalry charged repeatedly and brilliantly to cover the retreat of their infantry, and the combined Guard regiment created a panic in Corbineau’s brigade, and rode almost up to the walls of Polotsk. St. Cyr himself, who had been slightly wounded on the 17th and was obliged to use a carriage, was nearly captured, and the daring horsemen were only checked by the fire of the reserve artillery. They were fired into from all sides, and charged by one of Doumerc’s Cuirassier regiments, but the survivors regained the Russian line, sorely diminished in numbers, but covered with glory. The Russian army, badly defeated but by no means routed, made good its retreat during the night to Sivokhino, where it halted. St. Cyr did not pursue. He was not strong in light cavalry, and Corbineau’s brigade was obviously demoralised. Still it seems that more use might have been made of Merle’s Swiss regiments, which had scarcely fired a shot; several of Verdier’s and Wrede’s regiments also had not been heavily engaged.
