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