The human soldiers that were sieging Thenitsa at this time were led by Commander Armstrong.
Four days ago, Ahab sneaked out of Themisphylae fort and went to Thesewal. When he arrived, he found out that the border town had almost no enemy.
The third war chief who was maintaining a façade in front of Themisphylae fort received a report about enemies suddenly appearing near their captured town. He hurriedly tried to go back to prevent the border town from being retaken, but Duchess Isabelle came out and forced him to stay.
At the same time, Ahab sent a part of his force to halt the army under that war chief and also had Fierce Flame send a message to her friend who was with Commander Armstrong inside the fort in Slaughterer Plains. Commander Armstrong immediately brought his force out of the fort once he received the message. Together with Ahab, they retook Thesewal.
