Dennewitz (Campaign of Leipsic).
Fought September 6, 1813, between the French army of the north under Ney, and the allies under the Crown Prince of Sweden. Ney had detached Bertrand's division to mask Dennewitz, while his main body marched past the position on the road to Berlin, but Bertrand delayed so long before Dennewitz, that what was intended for a demonstration became a serious action, in which the full force of both sides was engaged. The French were defeated with a loss of 10,000 men and 43 guns.
