The success of guerrilla warfare during the Civil War in Oklahoma, or any other region, would depend on various factors such as terrain, local support, leadership, and the strategies employed. Guerrilla tactics can be effective in certain circumstances, but predicting their success in a specific historical context is complex and speculative. In Oklahoma during the Civil War, factors like the presence of Union and Confederate forces, the loyalty of the local population, and the ability to sustain guerrilla operations would have played crucial roles in determining their success.
