Prussian main army at Auerstädt, out of jealousy, and Napoleon, if reminiscences from St. Helena may be believed, once intended to put Bernadotte before a court-martial. In fact, he did what he had been ordered to do, and more fundamental responsibility for his absence rests upon the ambiguous and indirect orders issued by Berthier and Napoleon's unawareness of the Prussian position. Documentary evidence supports Bernadotte's assertion that he was ordered to Dornberg as no orders from Napoleon to Bernadotte to march with Davout were ever found in French Imperial Archives while Berthier's order of 14 October were confirmed. After the Battle of Jena, Bernadotte crushed the Prussian Reserve Army, all fresh troops fortified behind a marsh and the River Saale, under Duke Eugen of Württemberg at Halle (17 October 1806), though Imperial Headquarters did not much appreciate this victory. When visiting Halle after the battle, and commenting on the degree of difficulty of storming a fortified position accessible only by a single bridge, Napoleon enigmatically commented "Bernadotte stops at nothing. Someday the Gascon will get caught." Subsequently, Bernadotte pursued, conjointly with Soult and Murat (known as the "Pursuit of the Three Marshals"), Prussian general Blücher's Corps to Lübeck, where his troops stormed the Prussian defenses, taking the city and forcing Blücher's capitulation at Radkow (7 November 1806). When the French forced their way into Lübeck, the city became the target of large-scale looting and rampage by the French soldiers. Bernadotte, struggling desperately to prevent his men from sacking the city, was given six horses from the Council of Lübeck as a token of their appreciation. He also treated with courtesy 1600 Swedish prisoners, under the command of Colonel Count Gustave Mörner, and allowed them to return to their home country. The impressed Swedes went home with a tale of Bernadotte's fairness in maintaining order within the city. Count Mörner would later play a prominent role in the election of Bernadotte as Crown Prince of Sweden. Thereafter he marched to Poland in command of the French Left Wing, composed of his I Corps and Ney's VI Corps. Left unsupported by Ney's unexpected movement toward Königsberg, the Russians under Levin August von Bennigsen, passed over to the offensive and attempted to destroy Bernadotte's and Ney's isolated Corps. Napoleon, having received word of the Russian offensive, gave word to Bernadotte to retreat West as to draw the Russians toward him so that Napoleon
