The French have moved east and occupied Warburg
Due to poor staff work there is a bottle neck at Willingen
6th corps was unable to complete their march to C06 due to difficult terrain
This prevented 2nd corps marching towards Kassel.
The Russians have concentrated in the centre to take Kassel
In doing so they have left their depots at Gottingen and Kaufungen isolated
Both are a days march from the nearest corps
If the French push on to take either, they will also capture the stores held in the depots.
