The Jena campaign was arguably Napoleon's best. It 'featured' the destruction of the Prussian army and state in three weeks and exposed the Prussian civilian population with no will to resist and to be subservient.
It also featured the most relentless pursuit of a beaten enemy during the period. The Prussians were given no time to reorganize and make a stand. Lasalle was not the only French cavalry commander involved in the pursuit, and his bluffing the fortress of Stettin was an outstanding feat just as his thumping error (along with Klein) of allowing Blucher and Kalkreuth to escape after being intercepted on 16 October because they claimed that an armistice had been signed. Murat commanded the Cavalry Reserve during the pursuit, no Lasalle.
Blucher was forced to the northeast, took possession of Lubeck, was cornered and surrendered on 7 November. None of his operations had forced the French to stop the pursuit nor shift any substantial forces to face Blucher and his 'rear guard.' Blucher's surrender was forced because the French were pursuing any of the Prussian army they could get their hands on. In three weeks the French had captured 140,000 prisoners, 800 field pieces, and 250 flags and that doesn't count the Prussian dead and wounded at Jena and Auerstadt.
