"They tell us that we are weak - unable to cope with so formidable an adversary. But when shall we be stronger? Will it be when we are totally disarmed, and when a British guard shall be stationed in every house? Three million people, armed in the holy cause of liberty, are invincible by any force which our enemy can send against us." - Patrick Henry
