Despite the heavy shrinkage in the Grand Army caused by a remorseless rush through a country wellnigh stripped of supplies, the Emperor sought to force on a general engagement. He hoped to catch Barclay at Vitepsk. "The whole Russian army is at Vitepsk--we are on the eve of great events," he writes on July 25th. But the Russians skilfully withdrew by night from their position in front of that town, which he entered on July 28th. Chagrined and perplexed, the chief stays a fortnight to organize supplies and stores, while his vanguard presses on to envelop the Russians at Smolensk. Again his hopes revive when he hears that Barclay and Bagration are about to join near that city. In fact, those leaders there concluded that strategic movement to the rear which was absolutely necessary if they were not to be overwhelmed singly. They viewed the retreat in a very different light. To the cautious Barclay it portended a triumph long deferred, but sure: while the more impulsive Muscovite looked upon the constant falling back as a national disgrace. The feelings of the soldiery also forbade a spiritless abandonment of the holy city of the Upper Dnieper that stands as sentinel to Russia Proper. On these feelings Napoleon counted, and rightly. He was now in no haste to strike: the blow must be crushing and final. At last he hears that Davoust, the leader whose devotion and methodical persistence merit his complete trust, has bridged the River Dnieper below the city, and has built ovens for supplying the host with bread. And having now drawn up troops and supplies from the rear, he pushes on to end the campaign. Barclay was still for retreat; but religious sentiment and patriotism bade the defenders stand firm behind those crumbling walls, while Bagration secured the line of retreat. The French, ranged around on the low hills which ring it on the south, looked for an easy triumph, and Napoleon seems to have felt an excess of confidence. At any rate, his dispositions were far from masterly. He made no serious effort to threaten the Russian communications with Moscow, nor did he wait for his artillery to overwhelm the ramparts and their defenders. The corps of Ney, Davoust, and Poniatowski, with Murat's cavalry and the Imperial Guard posted in reserve, promised an easy victory, and the dense columns of foot moved eagerly to the assault. They were received with a terrific fire. Only after three hours' desperate fighting did they master the southern suburbs, and at nightfall the walls still defied their assaults. Yet in the meantime Napoleon's cannon had done their work. The wooden houses were everywhere on fire; a speedy retreat alone could save the garrison from ruin; and amidst a whirlwind of flame and smoke Barclay drew off his men to join Bagration on the road to Moscow (August 17th).
