The captain thought he had a valid point. If this was the box, it was better for it to reach the crown prince earlier to avoid unnecessary trouble.
"You will take the box and ride to the military camp of lowe. Then seek an audience with the crown prince," the captain said.
The guard assigned to the task got up and bowed. "I will obey the captain's order." Just as he moved to pick up the box, the captain stopped him.
"You, go," the captain said, pointing at his deputy. He would have delivered the box himself, but he felt he still had to manage the situation within the camp. Moreover, the deputy was better with words and should be able to explain the situation to the crown prince better than a guard.
The deputy saluted, picked up the box, and obeyed the command. He then requested that one of the men who found the box accompany him. If the box was indeed the one that should be in the crown princess's care, they might need to explain to the prince where they found it.
