The French Revolution's reign of terror

Melvyn Bragg and guests discuss the reign of terror during the French Revolution. On Monday September 10th 1792 The Times of London carried a story covering events in revolutionary France:
"The streets of Paris, strewed with the carcases of the mangled victims, are become so familiar to the sight, that they are passed by and trod on without any particular notice. The mob think no more of killing a fellow-creature, who is not even an object of suspicion, than wanton boys would of killing a cat or a dog".
These were the infamous September Massacres when Parisian mobs killed thousands of suspected royalists and set the scene for the events to come, when Madame La Guillotine took centre stage and The Terror ruled in France.

But how did the French Revolution descend into such extremes of violence? Who or what drove The Terror? And was it really an aberration of the revolutionary cause or the moment when it truly expressed itself?
