Overview: The two Russian Western Armies are trying to join up to mount a defense against Napoleon's invasion of Russia. But the speed of the French advance, particularly Marshal Davout and Marshal Murat, are putting pressure on the Russians. And so late July sees a series of battles at Mogilev/Saltanovka and Vitebsk/Ostrovno. Meanwhile the Russian 3rd Observation Army is dangerously close to the border of the Duchy of Warsaw - the Austrians under Schwarzenberg and Reynier's Corps need to stand and fight around Kobryn.
