For several months the insurgency fought against the Ethiopian army, swelling from just 300 to an estimated 3,000 to 12,000 insurgents (estimates greatly vary) and eventually forming a "liberation government". Many neutral Ogaden Somalis had been alienated by the loss of relatives, herds and homes in Ethiopian reprisal raids on their border villages, inflaming the resistance. and
Ethiopian-Somalia border The insurgencies surprising early success is attributed to the terrain advantage the
Ogaden offered, ideal for traditional
guerrilla hit-and-run tactics, placing the
mechanized troops at a large disadvantage. In response these centers were reinforced and deployed motor patrols, which were repeatedly ambushed by rebels seeking to obtain arms. The Ethiopian army's lackluster performance against the insurgents bolstered their confidence, encouraging them to expand their activities. However, their
hit-and-run tactics ultimately proved insufficient to weaken the strategic control of the
Ethiopian Empire. According to the
Central Intelligence Agency, Ethiopian Defense Minister General
Merid Mengesha would come under fire for the poor showing of the military against the Ogaden rebels. The Ethiopian government argued that the conflict was a result of armed bandits being sent across the border by Somalia to harass the country into ceding a large slice of Ethiopian territory, to which the Somali government repeatedly denied that the it either inspired or fomented the troubles in Ogaden. Despite the Ethiopian government's allegations, it was widely recognized that the Somali government could assert no real control over the Ogaden insurgents, as the rebels had made it clear that they were not willing to take orders from Mogadishu, despite desiring its recognition. A CIA report submitted to U.S.
President Lyndon B. Johnson would conclude, "Somali authorities show no ability to control the tribesmen whose depredations so infuriate the Ethiopians."
Suppression of insurgency and first border clashes In August 1963 Ethiopian forces regrouped and the 3rd Division of the Imperial Army swept back through the Ogaden with relative ease, aided an eight-week-long air campaign against Somali targets on both sides of the border and the inexperience of the guerrillas. Despite regaining control of large portions of the region the 3rd Division was unable to stamp out the insurgency. By September 1963 the insurgents were reported to have some 3000 members. The rebels were severely hampered by the lack of an integrated command structure and weaponry needed to combat the 3rd Division. That fall insurgents were noted to be active in

Kelafo, where they overran police stations and ambushed army convoys. == 1964 Border War and decline ==
