Napoleon is now ready to order his planned attack on Eilsben. But first he orders 13th Polish corps to attack 4th Prussian corps. His intention is to distract Blucher and hopefully prompt him to reinforce his left from his centre.
The Poles lose 2300 casualties to the Prussian 2000 casualties. In addition they lose their cavalry, gunners and an infantry brigade in rout. Decouz orders them to retreat and abandon Helmstedt.
