From Bastille, violence spread throughout the French countryside. Rumors were spread that the feudal lords had hired robbers to murder peasants. This rumor was not true, but it flamed fear that led to the peasants rising up against their local lords.
Peasants broke into manor houses, killed many of the nobles, and took possession of their properties. This wave of violence is known as the Great Fear.
Some folks never exaggerate--they just remember big.
