This essay examines the reciprocal contest of wills as mediated through the use of political violence from roughly 1773 to the end of the war in 1783. In other terms, it covers the escalating application of violence and how that led to outright war in April 1775, as well as the war itself. In both periods, violence was used to influence the will of one’s opponent and the political preferences of the undecided—but sometimes its political intent was exceeded, with escalatory effects. Three broad categories of violence are considered here. The first, “intimidative and catalytic” was primarily associated with the period from 1773 to 1776, in which violence was used by both sides, mostly publicly, to force political opponents to accede or step aside. Some of those efforts at intimidation catalyzed further violence, leading ultimately to armed military confrontation. Once the war had begun, the strong conventions associated with “war” shaped military behavior by both sides’ regular forces, although not always successfully, and always subject to logistical requirements. These behaviors form the second category of “Regular and Logistical.” The third category, “Retaliatory” was primarily associated with peripheral militia forces, which were much less restrained by the customs and usages of war, and often instead indulged in escalating retaliation.
