Consider the following: The United States is engaged in what some political and media leaders call an immoral war, a war that did not have to be fought. After a relatively easy initial conquest, the US Army finds itself faced with armed resistance to US occupation. US strategic goals have changed since the war began; domestic political opposition increases as insurgent activities prolong the war. Insurgent leaders monitor US domestic politics and adjust their strategy accordingly. US Army Soldiers adapt to the uncertainty and employ novel techniques to complex military and nonmilitary problems in a land where they are strangers and about which they have little understanding. Does this sound familiar? It should, but this description does not depict events from 2003 to 2007 in the Middle East-it describes events from 1898 to 1902 in the Philippines. Combat Studies Institute (CSI) is pleased to publish its 24th Long War Series Occasional Paper, Savage Wars of Peace: Case Studies of Pacification in the Philippines, 1900-1902, by CSI historian Robert Ramsey. In it he analyzes case studies from two key Philippine military districts and highlights several themes that are relevant to today's ongoing operations in the Long War. Between 1899 and 1902 the US Army was successful in defeating Filipino resistance to American occupation using what military leaders at the time called a combination of attraction and coercion. However, success came only after initial setbacks, disappointments, and significant changes in leadership, military strategy, and political adaptation. In the two regions of the Luzon Island analyzed in this occasional paper, Army leaders employed a mix of political and economic incentives, combined with military actions and strict martial law to subdue the resistance. The geographic isolation of the insurrectos on the Philippine archipelago was also an advantage for US forces. The capture of key insurrecto leaders provided critical intelligence, and their post-capture pledge of support for the new government helped break the resistance by 1902. This work highlights, among many other themes, the importance of perseverance, adaptability, and cultural understanding. Written at the request of the Command and General Staff College for use in their curriculum, we believe this occasional paper will be a valuable addition to the professional development of all Army leaders.
