For want of a nail

This horse can go no further. This messenger is almost finished

FOR WANT OF A NAIL

For want of a nail, a shoe was lost
For want of a shoe, a horse was lost
For want of a horse, a rider was lost
For want of a rider, a message was lost
For want of a message, a battle was lost
For want of a battle, a war was lost
And all for the want of a nail…
