The Prince waited til mourning to have his men gather lumber. He assist a few as lookouts to prevent a repeat. It have taken all day to gather enough for one siege weapon. Prince Charlien then assigned at least two dozen to lookout for trouble.

During the night, none of the lookouts notice that they have one too many. This extra one allowed the archer to sneak in. The archer notices a prime opportunity to sabotage. The archer places one of her unlit fire arrows. And then places an explosive charge.

When she is far enough from the placed bomb. She then lit an arrow and shot the placed fire arrow. She ran from it. And the light draws some of the lookouts. The fire reaches the explosive.

The splinter shot everywhere. Luckily for the lookouts, they ducked. Prince Charlien wakes among the new fire. He orders the lookouts to find the saboteur. And all others to put the fire out. He couldn't figure out how.

The extra lookout follows the other from the rear. And then quickly disappears from sight. It is easy to say that Prince Charlien's frustration is heard. And where did the spy go? Hidden among the background, the extra lookout hiding prone with debris on him.
