Greater Poland Uprising (1806) - Aftermath

Aftermath

The Pomeranian Campaign was ended by the capitulation of Königsberg on 15 June 1807, the later treaties of Tilsit and the recognition of the Duchy of Warsaw by the Kingdom of Prussia.

However, there was a more immediate effect. By the time of the uprising, the Prussian army, previously thought invincible, had been fought to almost the point of total liquidation. Napoleon had destroyed the majority of the Prussian army only months after the declaration of war, and the only significant force loyal to the Prussian regime left was garrisoning Prussian Poland. These troops were expected to reinforce the Russians and continue fighting the French. With this Polish uprising supported by French military operations, this was no longer possible for the simple reason that outside a handful of Prussian units who managed to escape and join the Russians, the Prussian army had been completely and systematically wiped out. Russia would face France alone.
