Being so resolved and having composed their quarrels, they first sent three men as spies into Asia (continent)Asia. These came to Sardis [28.0167,38.475] (Perseus) Sardis and took note of the king's army. They were discovered, however, and after examination by the generals of the land army, they were led away for execution.

They were condemned to die, but when Xerxes heard of it, he blamed the judgment of his generals and sent some of his guards, charging them to bring the spies before him if they should be found alive.

They were found still living and brought into the king's presence; then Xerxes, having inquired of them the purpose of their coming, ordered his guards to lead them around and show them his whole army. When the spies had seen all to their heart's content, they were to send them away unharmed to whatever country they pleased.
