There is a story that a detachment of the army of Mardonios wished to return at Thebes

"There is a story that a detachment of the army of Mardonios, having over run Megaris, wished to return to Mardonios at Thebes, but that by the will of Artemis night came on them as they marched, and missing their way they turned into the hilly region. Trying to find out whether there was a hostile force near they shot some missiles. The rock near groaned when struck, and they shot again with greater eagerness, until at last they used up all their arrows thinking that they were shooting at the enemy. When the day broke, the Megarians attacked, and being men in armour fighting against men without armour who no longer had even a supply of missiles, they killed the greater number of their opponents. For this reason they had an image made of Artemis Soteria (Saviour)."
