How soon was his warning as to the instability of French Governments to be fulfilled! A revolution had broken out in Paris, the dethronement of the Emperor had been proclaimed, and a Provisional Government instituted.

They at once declared that they were a government of national defence, they would not rest till the invaders were driven from the land, they appealed to the memories of 1792.

They were indeed ready to make peace, for the war, they said, had been undertaken not against France but against the Emperor; the Emperor had fallen, a free France had arisen; they would make peace, but they would not yield an inch of their country or a stone of their fortresses.
