The study of insurgency and counterinsurgency over the years provides a valuable tool for analysis in the current Global War on Terrorism. Failure to take into account and accurately assess political and military actions in such environments can lead to unintended consequences (potential civil war) affecting the stability of a country. Accurate assessment of the political and military actions does not guarantee success or failure, as every insurgency is a unique case, which requires observation and analysis through the strategic implications particular to each circumstance. One historical example for analysis is the British Military Mission (BMM) to Greece in 1942-44, which begs the question 'did the policies utilized by the British in balancing the opposing political and military objectives of rival guerilla forces delay or help bring about the Greek Civil War?' This monograph explores the question by analyzing the historical documentation of actual events that transpired during the mission and whether they delayed or help bring about the Greek Civil War. The British Military Mission to Greece from 1942-44 originated for the purpose of disrupting German supply lines to North Africa in support of British operations aimed at defeating the Germans at El Alamein. This twelve-man mission inserted into Greece to organize, coordinate and direct Greek guerilla factions against occupying Axis forces and sever crucial supply lines feeding German forces in North Africa. The initial target consisted of a viaduct supporting the single rail line running through the country. The British members of the mission in coordination with two rival guerilla factions successfully destroyed the viaduct and halted German supply flow for several weeks. The mission demonstrated that guerilla forces in conjunction with Allied support could accomplish critical missions tied to Allied strategy and opened the door for more ambitious plans for coordinated guerilla warfare throughout Europe. The ensuing growth of coordination and support to guerilla factions by the British mission quickly revealed ulterior motives on the part of one guerilla faction dominated and controlled by the Greek Communist Party (KKE). This faction was determined to gain control of resistance operations throughout Greece and ultimately bring Greece under Communist control. The ensuing struggle to balance immediate military objectives for the overall war effort and political goals between the rival guerilla factions dominated the British mission from 1942 until Greece's liberation in 1944. The British whole-heartedly supported the King of Greece and the government-in-exile while at the same time lending funding and support to guerilla factions that vehemently opposed the return of the king after the war. The dichotomy between British policy and actions on the ground presented difficulties in achieving immediate military objectives and complicated long-term stability for Greece. In conclusion, the ingredients for civil war existed long before the introduction of the British mission. Events shaped through decisions by Greek leadership and policies in the years leading to World War II are largely responsible for creating rifts between monarchist and antimonarchist forces and the spark toward civil war. The early introduction of the British Military Mission interjected a small force effectively bringing together two rival guerilla factions and temporarily delaying an inevitable civil war. While elements of British policy complicated the process, the nature of the political situation combined with long existing fault lines within Greek Government presented a strategic situation in which the best the British could hope for was a temporary solution.
