Plutarch records a quote from the Spartan king when he first witnessed engines of war being used:

When he saw the missile shot by a catapult, which had been brought then for the first time from Sicily, he exclaimed, "Great Heavens! man's valour is no more!"

Observation: It's not inaccurate that being squashed by a distant catapult nullifies all your warrior training, but even that wasn't the end of man's valor.

"Adapt and overcome.”
