As with its leadership and organisation, the aims and objectives of SOE changed throughout the war, although they revolved around sabotaging and subverting the Axis war machines through indirect methods. SOE occasionally carried out operations with direct military objectives, such as Operation Harling, originally designed to cut one of the Axis supply lines to their troops fighting in North Africa. They also carried out some high-profile operations aimed mainly at the morale both of the Axis and occupied nations, such as Operation Anthropoid, the assassination in Prague of Reinhard Heydrich. In general also, SOE's objectives were to foment mutual hatred between the population of Axis-occupied countries and the occupiers, and to force the Axis to expend manpower and resources on maintaining their control of subjugated populations.
