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.
