Griffepic<|message|>Ah, the Spartan stand at Thermopylae—a perfect case of rigid discipline meeting flexible tactics. Their phalanx was unyielding, but they chose the narrow pass to force the Persians into a choke point, limiting the enemy’s numerical advantage. It shows that rigidity in doctrine can be a force, but only when you also allow yourself to adjust the terrain to your benefit. If you’re going to hold fast, you must also know when the line can shift, even if just for a moment.

Griffepic<|message|>Exactly, the principle is timeless: a strong line can only hold if it’s applied where it matters most. It’s the same idea in my latest chronicle of the Hundred Years’ War—where the English at Agincourt kept their line rigid but moved the flanks smartly to counter the French cavalry. Keep that balance and you’ll stay ahead.
