The third day after the battle, the Hanoverian army had received no news of the Bavarian army, and was surrounded by 30,000 men.
Towards midday, a lieutenant-colonel came with a flag of truce, from General Manteuffel, to propose that the king should surrender.
The king replied that he knew perfectly well that he was hemmed in on all sides, but that he, his son, his major-general, his officers, and soldiers, from the highest to the lowest, preferred to die, unless an honourable capitulation were offered them.
At the same time he called a council of war which declared unanimously for a capitulation, as long as it was honourable. There was, indeed, no choice. The army had only three hundred shells left, and rations for one night and day. The whole court, the king included, had dined on a piece of boiled beef and potatoes; the soup was given to the wounded. Every man was allowed but one glass of bad beer.
Each article of the capitulation was discussed, so as to spin out the delay as long as possible. The speedy arrival of the Bavarians was still hoped for.
At length, during the night, the following conditions were drawn up, between General Manteuffel for the King of Prussia, and General von Arentschild for the King of Hanover.
The Hanoverian army was to be disbanded and the soldiers sent back to their homes. All the officers and non-commissioned officers were to go free. They were to retain their arms and equipments. The King of Prussia was to guarantee their pay. The king, the prince, and their suite were to be free to go wherever they wished. The king's private fortune was to be intact and inviolable.
The capitulation being signed, General Manteuffel went to the king's quarters. Entering his cabinet he said to him:
"I am sorry, sire, to present myself before Your Majesty in such sad circumstances. We understand all that Your Majesty suffers, we Prussians who have known Jena. I beg Your Majesty to tell me to what place you wish to retire, and to give me my orders. It shall be my duty to see that you suffer no inconvenience on your journey."
"Sir," replied the king coldly, "I do not know where I shall await the finding of the congress which has to decide whether I shall remain king, or become once more a simple English prince. Probably with my father-in-law, the Duke of Saxe-Altenburg, or with His Majesty the Emperor of Austria. In either case I have no need of your protection, for which I thank you."
