"To say that the morale of the Istrion Army was at an all-time low would have been a severe understatement. Rumour flew with the speed of wings, and everyone at field headquarters knew that the Semaskans had destroyed every fort and camp from there to the border. And now they were heading for the Istrion field headquarters, where the bulk of the remaining army waited for them."
