midnight
An hour before the arrival of Frederic and the so-called agent , the four sails of the windmill had fallen , bringing down in their fall the balustrade which surrounded it . So that to day one must conclude that there are no longer judges in Berlin , as there is no longer a mill at Sans-Souci . On their return to Potsdam , Frederic and his companion found a table ready laid for two . They dined alone together , played five games of chess out of which the agent won three , and it was only at midnight that they separated , when on the agent wishing Frederic a good night , the latter replied with a deep bow : `` Sire , may God grant Your Majesty a good night . '' The next day the fiction was abandoned . The king breakfasted with Frederic , gave him the Order of the Red Eagle , and with much pressing induced him to hand in his resignation and join the army . A week later he received his commission as lieutenant of the line , and came to pay his respects in his new character to the king , who undertook that the king would ever remember him whom the prince had promised not to forget .
