In the East an excessive importance is attached to this proof of success; and there were reasons which made Crassus particularly obnoxious to his antagonists.

He was believed to have originated, and not merely conducted, the war, incited thereto by simple greed of gold.

If he escaped, he would be bound at some future time to repeat his attempt; if he were made prisoner, his fate would be a terrible warning to others.

The highlands of Armenia would be gained by the fugitives during the night, and further pursuit of them would be hopeless.
