nine o'clock
`` Ah , I will silence this seditious rabble and make their faces mild and modest ! '' cried the general , in a threatening voice . `` Let all the public places in the city be occupied by troops , and field-pieces be placed on the bridges of the Inn . Let patrols march through the streets all night , and every citizen who is found in the street after nine o'clock , or keeps his house lighted up after that hour , shall be shot . Make haste , gentlemen , and carry my orders literally into execution . Have the patrols call upon all citizens to keep quiet and not appear in the streets after nine o'clock . Sentence of death will be passed upon those who violate this order . ''
