The next day Lasalle and his hussars marched to the fortress of Stettin, arriving well ahead of the main French force.
He prepared to attack but decided to try a bluff instead.
Pretending that the entire army had arrived, he demanded that Stettin surrender.
General Romberg's reply was predictable:. "
Tell your master that the town of Stettin was entrusted to my safeguard and that I shall defend it to my last man".
Lasalle then resorted to threats: "If, by 8 a.m. you have not surrendered, the town will be bombarded by our artillery, stormed by 50,000 men, the garrison will be put to the sword and the town will be plundered during twenty-four hours".
 Convinced that he was faced with 50,000 French soldiers, Romberg entered into negotiations and capitulated on the evening of 29–30 October.
Over 5,000 men and 281 guns were surrendered, and Lasalle became a national hero.
Napoleon wrote to Murat, "If your Light Cavalry captures fortified towns, I’ll have to discharge my Engineer Corps and have my heavy artillery melted down".

In spite of their victory, Lasalle's troops were exhausted.
He later wrote: "Who could recognize the brilliant hussars from Kronach fourteen months ago, those of the 5th Regiment with their white pelisses with lemon-yellow braids and their sky-blue breeches, those of the 7th Regiment with their green pelisses with daffodil-yellow braids and their scarlet breeches?
Today the whole brigade, men and horses adorned alike in mud, have neither form nor color.
Their uniform is misery".
