Well, I didn't exactly specify which guerilla war I was talking about, so it's partially my fault, but you should probably have inferred which one it was, based on my comment of Korea failing to remain independent. I meant that a significant amount of Joseon soldiers, whether they were originally peasants or had already been to begin with, would continue to resist the Qing soon after it took over the peninsula. For comparison, Goryeo resisted the Mongols for almost 40 years, and even after the ruler capitulated, the Sambyeolcho Rebellion lasted for three years afterward. As Joseon had recently repelled the Japanese by harassing the navy under Yi Sun-shin's leadership, and eventually stalled the army through guerilla warfare, it's very possible for Joseon to attempt to do the same a few decades later. However, this would also come at a terrible cost, as the population would be devastated, as I stated earlier.
