Note 192 — Chapter III

Yet "the Carduchian mountains," observes Rennell, "in effect presented an asylum to the Greeks, who could no other way have escaped, at least, the reiterated attacks of such a host of enemies, whose numbers also were augmenting instead of diminishing. But as a Persian army could not subsist, or their cavalry act, within the wide range of these mountains, the Greeks, by ascending them, got rid of their dreaded enemy. And although, in the mean time, they had to contend with an enemy much more brave and persevering, their numbers were fewer, and they might reasonably expect an earlier escape from them than from the Persians. Had they known that the Tigris was fordable under the Zaco hills, and passed into Mesopotamia, they would still have had the Euphrates to cross, a yet more difficult river, in the line which they must have pursued. Therefore, according to our limited view of things, it appears that nothing less than such a barrier as these mountains presented, could have saved the Greeks from eventual destruction, from the attacks of the Persians."
