The defending army took no prisoners when they stopped the attack. They did take the cocks and balls of the every invader. Captured warriors were allowed a final orgasm. They were given the choice between a sword to the heart or to the belly, and were dispatched as they shot their final wad. Cheers always went up from the crowd of bystanders as each prisoner met his fate.
The right hand, helmet, soldier holding a set of cut cock and balls behind his back is impressive. It's rewarding that his own cock is spurting. Meanwhile, the central, bound, figure enjoys the blade cutting off his spurting cock and balls. It's reassuring that these cut cocks and balls bring good fortune to households.
It's likely that the defeated warriors experienced the most desperate and intense orgasms of their lives in the instant before their manhood was hacked off. Repurposed as good-luck charms in the households of their enemy, the cocks of the doomed studs were still flowing with deathcum at the time they were harvested.
