After four days of fighting both armies are in disorder and most corps have casualties.
The Prussian Army has come off worse during the previous four battles, and there is a general movement to the east. In doing so they have broken contact with most of the French corps, some of whom are regrouping and preparing for an advance east.
Communications between CinC and the furthest corps has also suffered due to the upheaval of the past few days. It is taking up to four moves for some reports to reach both Blucher and Davout, and the same again for their orders to arrive. As a result those corps furthest from the CinC have been authorized to act on their own initiative.
