The almost total annihilation of the Prussian army at the battle of Jena, opened the gates of Berlin to Napoleon. On the 25th of October, 1806, he was at Potsdam, and visited the royal castle, Sans Souci. The Prussian Court had abandoned Potsdam and Berlin so precipitately, that nothing had been removed from the king’s palace. Napoleon made his solemn entry into Berlin on the 27th.

The war with Prussia was thus ended. Of the 150,000 men who formed the main body of the Prussian army, seven-eighths had been killed or made prisoners; and the army of Frederic-William now consisted of only 20,000 men, infantry and cavalry. The king, the queen, and some of the Prussian generals who had sought refuge in Koenigsberg, were reduced to so deplorable a situation that they were obliged to throw themselves on the generosity of the conqueror, and sue for peace. This was granted.

The French Senate complimented the Emperor on his success; and received from him the ensigns won from the enemy in that splendid campaign. Three hundred and forty banners and standards taken at Jena, as well as the sword, scarf, collar, and ribbon of Frederic the Great, were sent to the deputies to be placed under their care in the Hotel des Invalides.
