Par Ung Seul Clou Perd On Ung Bon Cheval

For want of a nail the shoe was lost.

For want of a shoe the horse was lost.

For want of a horse the rider was lost.

For want of a rider the battle was lost.

For want of a battle the kingdom was lost.

And all for the want of a horseshoe nail.

-Proverbial Rhyme, 'For Want of a Nail'
