When the first person surrenders, then there's a good chance the rest will surrender as well—battles often unfold this way.
This battle had lasted less than five minutes from start to finish. By the time Gao Yuan swept his gaze across the battlefield, he found that most of the enemy had chosen to kneel and surrender. Their movements were skilled, methodical, and standard.
Of course, some refused to surrender. A standard squad stubbornly held out, and from their tactical maneuvers and fighting spirit, they appeared quite resilient. But the situation was no longer something that willpower alone could reverse, so this group of a dozen combatants was swiftly wiped out to the last man.
Then, when Sirte and Klaus finally arrived on the scene, what they saw were captives kneeling in a circle, being searched one by one.
"What happened..."
Bewilderment, incomprehension, extreme confusion.
