In 1858, Queen Victoria asked Churchill to accompany her eldest daughter Princess Victoria to Berlin, upon her marriage to Prince Frederick of Prussia. The historian Helen Rappaport attributes this newly assigned role to the Queen "no doubt impress[ed with Churchill's discretion and dependability". The Queen wished that Churchill help Vicky acclimatise to life in the Kronprinzenpalais, and to send back her observations of even the smallest details of life there. Churchill stayed with the princess for several weeks, reporting back to the queen on conditions. One source of displeasure was the hot temperature of the rooms, which Churchill described as "dreadful".
