Napoleon has won the Salzwedel campaign
Blucher has suffered a crushing defeat at Salzwedel, and has no alternative but to order a general retreat.
2nd corps and the reserve are in rout and he has no control over them
1st corps has won a convincing victory at Dahre and his left flank is secure. But with the loss of his centre they must also retreat to avoid being cut off.
3rd corps could hold its own at Kladen, but is not strong enough to attack to raise the siege. Again they must retreat to avoid being cut off.
Napoleon occupies Salzwedel with 1st corps, and by doing so has won the campaign.
The French reserve are out of supply, and will suffer attrition casualties. But despite this he orders them to advance with 1st corps. This is just in case Blucher attempts to retake the city with 1st and 3rd corps.
3rd French corps are battered and will need a few days to recover from their defeat a Dahre. They are ordered to rally and resupply at Gifhorn.
