Plataea

And, after Laches changes his mind and admits that the Scythians, and cavalry units in general, made use of it, he reminds him also that, at the battle of Plataea, when the Spartan infantry, famous for standing its ground, found itself unable to open up the Persian phalanx, it decided to withdraw and walk back, feigning a retreat, and thus let this mass break and disperse as it pursued them, by which means they earned their victory.
