Innovation in Intelligence: An Analysis of U.S. Marine Corps Intelligence Modernization during the Occupation of Haiti, 1915-1934

Increasing modernization in military technology and methodology occurred during the beginning of the twentieth century. These changes had a direct effect on how U.S. Marines practiced military intelligence during the occupation of Haiti from 1915- 1934. The use of military intelligence had an impact on the outcome on the occupation but was not the only factor that contributed to U.S. military victories. My thesis explains that the improvement of intelligence methods used by Marines in Haiti occurred as a result of outside influence, changing circumstance in Haiti, and individual agency. Major failures had occurred that allowed resistance to grow unchecked in the Haitian countryside. With the introduction of full-time military intelligence officers and improved data documentation, the intelligence collected became more useful to Marine Corps leadership. The staff officers that assumed the roles of intelligence personnel created new forms for recording intelligence reports and made past intelligence more accessible to military command. Individual ingenuity led to the assassination of Charlemagne Peralte, the central leader of the caco revolt. This thesis discusses the intelligence innovation that occurred during the occupation of Haiti from 1915 to 1935
