Emily Davison
In 1909, she was sentenced to a month's hard labour in Strangeways Prison in Manchester after throwing rocks at the carriage of chancellor David Lloyd George. She attempted to starve herself, and resisted force-feeding. A prison guard, angered by Davison's blockading herself in her cell, forced a hose into the room and nearly filled it with water.  She sued the wardens of Strangeways, and was awarded 40 shillings.
