[Picture: Persian soldier] After this answer, Mardonius marched again into Attica, and took possession of it; but as the Athenians were now all safe in Salamis, or among their friends, he could not do them much harm; and while he was finishing the ruin he had begun ten months before, the Spartans had raised their army, under the command of their king, Pausanias, nephew to Leonidas, and all the best soldiers from the other Greek cities.  They came up with the Persians near the city of Platæa. Though a Spartan, Pausanias had rather not have fought; but when at last the battle began, it was a grand victory, and was gained in a wonderfully short time.  The Spartans killed Mardonius, and put the best Persian troops, called the Immortals, to flight; and the Athenians, under Aristides, fought with the Thebans, who had joined the Persian army.  The whole Persian camp was sacked.  The Helots were sent to collect the spoil, and put it all together.  They stole a good deal of the gold, which they took for brass, and sold it as such.  Waggon-loads of silver and gold vessels were to be seen; collars, bracelets, and rich armour; and the manger of Xerxes’ horses, which he had left behind, and which was of finely-worked brass.  Pausanias bade the slaves of Mardonius to prepare such a feast as their master was used to, and then called his friends to see how useless were all the carpets, cushions, curtains, gold and silver, and the dainties upon them, and how absurd it was to set out on a conquering expedition thus encumbered.
