Among the ways the Spartans differ from other peoples is this. When an ally in distress applies to them for aid, they alone dispatch neither troops nor treasure but a solitary commander, a general. This officer alone, assuming charge of the beleagured forces, is sufficiant, they feel, to turn affairs about and produce victory. This as the world knows is what happened at Syracuse.
