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 Kœnigsberg, 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_.

This honor was the recompense for the glorious part which these brave troops had taken in the battle of Jena. A favor so simple, rivalling in that respect the oak leaf chaplet of the Romans, intoxicated the soldiers who received it, and they swore to be to the Emperor, what the Tenth Legion was to Cæsar. He visited the vault where the remains of Frederic were deposited in a coffin of cedar-wood, encased in another of brass, without ornament or pompous inscription. Napoleon forbade the passage of the colors, eagles and cannon taken from the Prussians, over the place where the ashes of the illustrious monarch reposed lest it might distress his shade, or seem an insult to his tomb. The memorable spoils of which we have spoken in giving an account of Napoleon’s visit to Frederic’s grave, were received in Paris with wild delight, and deposited with much pomp in the _Hotel des Invalides_, under guard of the veterans. Amongst these were yet alive 900 who had borne arms against Frederic, and they received with gratitude, presents which in their old age renewed remembrances of the army and its immortal chief. Like the warriors of Sparta, they were proud of being surpassed by their children. [Illustration: THE SWORD OF FREDERICK THE GREAT.] THE BATTLE OF JENA. Napoleon arrived at Jena on the 18th of October, 1806, and soon divined that it was the intention of the Prussians to fight on the morrow. Giving orders to Davoust and Bernadotte, and not waiting for the guard, which were thirty hours’ march away, he determined on beginning the attack himself. Lannes ranged his corps on a plateau in front of Jena, which the Prussians had unwisely neglected to occupy. Lefebvre and the Imperial Guard formed in a square upon the summit, and Napoleon bivouaced in the midst of his troops.
