Prior to making war on Persia Croesus had invested heavily in a prophecy from the Oracle at Delphi. But more of that later.
Before the game I looked up the battle in my 1930 edition of Heredotus and was entertained to see that Croesus was warned by a wise Lydian by the name of Sandanis about attacking the Persians: "Thou art about oh! king, to make war against men who wear leathern trousers, and have all their other garments of leather..." Not the image of Persians that I had!
The Lydian right - with actual heavy cavalry!
Back in 547BC the battle was bloody but indecisive so Croesus marched off back to Sardis, his capital and there paid off his army all the time thinking "I'll have another go next year." What he hadn't reckoned with was that Cyrus would follow him home. The rotter.
And the Delphic prophecy? "If King Croesus should cross the Halys River, a great empire will fall." One did. Sadly his own.
