The following text is from Edward Rowland Sill's poem "Opportunity."

This I beheld, or dreamed it in a dream:— 

There spread a cloud of dust along a plain; 

And underneath the cloud, or in it, raged 

A furious battle, and men yelled, and swords 

Shocked upon swords and shields. A prince's banner 

Wavered, then staggered backward, hemmed by foes. 

A craven hung along the battle's edge, 

And thought, "Had I a sword of keener steel— 

That blue blade that the king's son bears,—but this 

Blunt thing—!" He snapt and flung it from his hand, 

And lowering crept away and left the field. 

Then came the king's son, wounded, sore bestead, 

And weaponless, and saw the broken sword,

Hilt-buried in the dry and trodden sand, 

And ran and snatched it, and with battle-shout 

Lifted afresh, he hewed his enemy down, 

And saved a great cause that heroic day.
