ORAC, that is what the Chinese used to do thousands of years ago, to surround a city and leave an avenue of escape. The hope was that the city would fall easily, and with no bloodshed for either the attackers or for the defenders..
Great read and all-time world classic if anyone has the time and inclination, and if you have already finished with Shakespeare, etc. Takes some getting into because of all the names, but it made me realize that the Chinese are still living this history as if it never grew old.
