Before we give the result of Lauriston's mission, it is proper to trace the movements of the Russian grand army, since their melancholy march through the city of Moscow. They left the city by the route of Kolomna, and marched for two days in that direction; and having thus imposed on the enemy a belief, that they were bent in securing a retreat to the south-east, leaving at once the eastern and southern provinces undefended, Koutousoff executed one of the most dexterous movements of the Russian army during the campaign. The observation of the Petersburgh road was intrusted to Winzengerode, with a small flying army. Koutousoff himself, turning to the southward, performed a circular march, of which Moscow was the centre, so as to transfer the grand army to the route towards Kalouga. They marched in stern dejection; for the wind, great as the distance was, showered among their ranks the ashes of their burning capital, and in the darkness, the flames were seen to rage like a huge ocean of fire. The movement was a bold one also, for, although performed at a respectful distance from the French army, yet the march was for three days a flank march, and consequently of a very delicate character. The Russians manœuvred, however, with such precision, that they performed their movements in perfect safety; and while the French troops, who had been sent in their pursuit, were amusing themselves with pursuing two regiments of horse, which had been left on the Kolomna road, they were astonished to find that the grand Russian army had assumed a position on the south-eastern side of Moscow, from which they could operate upon and harass, nay, intercept at pleasure, Napoleon's line of communication with Smolensk and with Poland, and at the same time cover the town of Kalouga, where great magazines had been assembled, and that of Toula, famed for the fabrication of arms and artillery.[171]
