While this battle was going on, another was in progress near Auerstadt, where Marshal Davout had encountered the forces of the Duke of Brunswick, with whom was Frederick William, the king. Bernadotte, ordered by the emperor to occupy Hamburg, had withdrawn his troops, leaving Davout much outnumbered by the foe. But heedless of this, he threw himself across their road in the defile of Koesen, and sustained alone the furious attack made upon him by the duke. Throwing his regiments into squares, he poured a murderous fire on the charging troops, hurling them back from his immovable lines. The old duke fell with a mortal wound. The king and his son led their troops to a second, but equally fruitless, attack. Davout, taking advantage of their repulse, advanced and seized the heights of Eckartsberga, where he defended himself with his artillery. Frederick William, discouraged by this vigorous resistance, retired towards Weimar with the purpose of joining his forces with those of the Prince of Hohenlohe and renewing the attack. Davout's men were too exhausted to pursue, but Bernadotte was encountered and barred the way, and the disaster at Jena was soon made evident by the panic-stricken mass of fugitives, whose flying multitude, hotly pursued by the French, sought safety in the ranks of the king's corps, which they threw into confusion by their impact. It was apparent that the battle was irretrievably lost. Night was approaching. The king marched hastily away, the disorder in his ranks increasing as the darkness fell. In that one fatal day he had lost his army and placed his kingdom itself in jeopardy. "They can do nothing but gather up the _débris_," said Napoleon. [=The Demoralization of the Prussian Forces=] The French lost no time in following up the defeated army, which had broken into several divisions in its retreat. On the 17th, Duke Eugene of Wurtemberg and the reserves under his command were scattered in defeat. On the 28th, the Prince of Hohenlohe, with the 12,000 men whom he still held together, was forced to surrender. Blucher, who had seized the free city of Lübeck, was obliged to follow his example. On all sides the scattered _débris_ of the army was destroyed, and on October 27th Napoleon entered in triumph the city of Berlin, his first entry into an enemy's capital. [=Napoleon Divides the Spoils of Victory=] The battle ended, the country occupied, the work of revenge of the victor began. The Elector of Hesse was driven from his throne and his country stricken from the list of the powers of Europe. Hanover and the Hanseatic towns were occupied by the French. The English merchandise found in ports and warehouses was seized and confiscated. A heavy war contribution was laid upon the defeated state. Severe taxes were laid upon Hamburg, Bremen and Leipzig, and from all the leading cities the treasures of art and science were carried away to enrich the museums and galleries of France.
