They were assured that it was only a family affair , a demonstration such as had been made three days before under the windows of Count von Bismarck -- only it was the other way about ! Now the Hanoverian police was an excellent body , which highly approved of family fêtes and patriotic demonstrations . Therefore , instead of objecting to this one they encouraged it with all their power , thanks to which all passed off in perfect order . At midnight , Benedict was at length allowed to retire , but his admirers organized a serenade beneath his windows which lasted till two o'clock in the morning . At nine Kaulbach entered his room . The Crown Prince invited Benedict to breakfast at the Palace of Herrenhausen , and requested him to bring his sketches . Kaulbach was commissioned to bring him back .
