“ With far less ability than his father for their execution, Cambyses conceived even vaster projects of conquest and dominion. Asia had hitherto usually afforded a sufficient field for the ambition of Oriental despots. Cambyses determined to add the country of Africa to the vast inheritance received from his father. Upon some slight pretext, he invaded Egypt, captured Memphis, and ascended the Nile to Thebes. From here he sent an army of fifty thousand men to subdue the oasis of Ammon, in the Libyan desert. Of the vast host not a man returned from the expedition. ”
