What unknowable mercy has spared us this day? What clemency of the divine has turned the enemy's spear one handbreadth from our throat and driven it fatally into the breast of the beloved comrade at our side? Why are we still here above the earth, we who are no better, no braver, who reverenced heaven no more than these our brothers whom the gods have dispatched to hell?"

In this speech from Steven Pressfield's gripping, well-researched re-telling of the Battle of Thermopylae (Gates of Fire), the Spartan King Leonidas addresses his troops after a victory. He is reflecting on the fact that when you do battle in chaos, Lady Fortuna and skill have an equal say in the outcome. Pressfield explains this dynamic in his equally worthwhile non-fiction work, The Warrior Ethos:

"In the era before gunpowder, all killing was of necessity done hand to hand. For a Greek or Roman warrior to slay his enemy, he had to get so close that there was an equal chance that the enemy's sword or spear would kill him. This produced an ideal of manly virtue – andreia, in Greek – that prized valor and honor as highly as victory."
