In spite of all the interruptions, I was able to speak for about an hour and a half and I felt as if I were master of the situation. Even the ringleaders of the disturbers appeared to be convinced of this; for they steadily became more uneasy, often left the hall, returned and spoke to their men in an obviously nervous way.

A small psychological error which I committed in replying to an interruption, and the mistake of which I myself was conscious the moment the words had left my mouth, gave the sign for the outbreak.

There were a few furious outbursts and all in a moment a man jumped on a seat and shouted "Liberty". At that signal the champions of liberty began their work.
