Rarely, if ever in human history, has any coherent, organized army been able to permanently put down a sustained, well-supplied and locally supported partisan movement. Armies can defeat armies, but they simply cannot keep fighting a war with what we, today, refer to as insurgents. It becomes too costly, and, unlike the American revolutionaries, the British had no viable way of producing loyal soldiers in the colonies, much less fanatics that did not play by the rules of 18th century combat. The war could well have gone on and on and on, taxing both sides and turning the colonies into a wasteland, but, in the end, it would simply have proven unsustainable for the British, no matter how great their technological superiority.
