For the want of a nail, the horseshoe was lost; For the want of a horseshoe a horse was lost; For the want of a horse, the rider was lost; For the want of a rider, the message was lost; For the want of a message, the battle was lost; For the want of a battle, the war was lost; For the want of a war, the kingdom was lost; And all for the want of a horseshoe's nail.
