The plan was perfectly successful. The men passed into Persia without any suspicion. They delivered the hare to Cyrus, with their message. He opened the hare, and found the letter. It was in substance as follows:
"It is plain, Cyrus, that you are a favorite of Heaven, and that you are destined to a great and glorious career. You could not otherwise have escaped, in so miraculous a manner, the snares set for you in your infancy. Astyages meditated your death, and he took such measures to effect it as would seem to have made your destruction sure. You were saved by the special interposition of Heaven. Yon are aware by what extraordinary incidents you were preserved and discovered, and what great and unusual prosperity has since attended you. You know, too, what cruel punishments Astyages inflicted upon me, for my humanity in saving you. The time has now come for retribution. From this time the authority and the dominions of Astyages may be yours. Persuade the Persians to revolt. Put yourself at the head of an army, and march into Media. I shall probably myself be appointed to command the army sent out to oppose you. If so, we will join our forces when we meet, and I will enter your service. I have conferred with the leading nobles in Media, and they are all ready to espouse your cause. You may rely upon finding every thing thus prepared for you here; come, therefore, without any delay."
Cyrus was thrown into a fever of excitement and agitation on reading this letter. He determined to accede to Harpagus's proposal. He revolved in his mind for some time the measures by which he could raise the necessary force. Of course he could not openly announce his plan and enlist an army to effect it, for any avowed and public movement of that kind would be immediately made known to Astyages, who, by being thus forewarned of his enemies' designs, might take effectual measures to circumvent them. He determined to resort to deceit, or, as he called it, stratagem; nor did he probably have any distinct perception of the wrongfulness of such a mode of proceeding. The demon of war upholds and justifies falsehood and treachery, in all its forms, on the part of his votaries. He always applauds a forgery, a false pretense, or a lie: he calls it a stratagem.
