Only the Prussians continue to resist French domination of all the Germanies.  We are hotly engaged with their main forces west of Berlin, and expect victory before much longer.  However, it has come to the Emperor's attention that the Russians are beginning to mobilize.  We suspect that they will try to grab Prussian territory while the Prussians are occupied fighting us.  Your task, General, is to prevent this if possible.  An attack on the southern front is being prepared to allow you to break through into the Prussian rear areas.  Berlin is not an objective in this mission, avoid its powerful defences.  You must overrun the local garrisons and take up a position on the Oder.  If the Russians move, we want the new border to be on the river, not to the west.  Be aware that you will be operating beyond the range of our aircraft until you can capture an airfield.
