In addition to the above two anti-colonial armed forces, the anti-colonial armed forces led by the National Union for the Total Independence of Angola (UNITA) appeared in March 1966. The chairman of UNITA is Jonas Savimbi. UNITA established guerrilla bases in the eastern region and established the Angolan Liberation Army. Although the three armed forces dealt a heavy blow to the colonial government, they scattered their forces, dealt a weak blow to the enemy and planted the seeds of discord.
From the second half of 1960s to the first half of 1970s, the anti-colonial armed struggles in Guinea-Bissau, Angola and Mozambique continued to develop, patriotic forces further expanded in the struggle, guerrilla base areas were further expanded and consolidated, and attacks on colonial military police were more frequent and larger.
In Angola, the armed struggle led by three nationalist organizations has been strengthened. During the period of 1968, the guerrilla warfare of the People's Liberation Army in the eastern region has expanded to Lunda and Bie provinces. By the early 1970s, its armed forces had reached five military regions: Danbos, Kabunda, Moxico and Kuandokubango, Lunda, Malange and Bie. The guerrilla activities of ANLF also extended to Zarea, Uige, Kwanza Norte, Luanda, Kabunda, Malange, Lunda and Moxico provinces. The armed struggle of UNITA also gradually developed from moxico province to parts of Lunda, Malange, Bie and Kuando Kubango provinces, and then extended to parts of Vera province in May 1969.
In order to destroy Angola's anti-colonial patriotic forces, the Portuguese colonial authorities ignored human nature and imitated all the means used by the United States in Vietnam. At the end of 1967, the colonists forced Angolan farmers who had been scattered to live in designated places. Some settlements are surrounded by barbed wire and other obstacles. Colonists believed that this could prevent guerrilla infiltration, cut off the contact between local residents and guerrillas, and isolate, weaken and destroy patriotic armed forces. However, the life in the concentration camp made the people more dissatisfied with the colonial authorities and more sympathetic and supportive of the guerrillas' anti-colonial struggle. 1970, the colonists also launched a biological war, spraying chemicals over the fields with airplanes, resulting in large-scale death of crops.
With the support and cover of the broad masses in the base areas and enemy-occupied areas, the Angolan patriotic armed forces launched guerrilla warfare with the enemy by taking advantage of the favorable environment with high mountains and dense forests in the territory. They set up roadblocks, laid mines in blow up bridges, cut off power lines and telephone lines, lured the enemy into ambush circles, resisted the enemy's sweeping, annihilated the effective forces of the colonial military police, and often attacked the enemy's military strongholds and patrols, burning down colonial plantations, making the enemy exhausted. 1On July 25th, 974, the National Liberation Army wiped out a Portuguese post in the northernmost part of Angola, annihilated nearly 100 defenders, and created a famous war example. According to incomplete statistics, by 1974, the anti-colonial armed forces led by three nationalist parties in Angola had grown to 15000, liberating two-thirds of the country and more than1000 people. .
1In the second half of the 1960s, the patriotic armed forces of Guinea-Bissau continued to smash the enemy's attacks. 1May 1968 to1February 1969, when two battalions of colonial troops invaded the southern border area in an attempt to cut off the transportation line in the liberated areas, patriotic armed forces finally defeated the enemy with circuitous tactics after nine months of fighting, thus preserving this important transportation line. In late February, patriotic armed forces won another great victory in Moles Liberated Area. Thousands of people were killed or injured in the colonial army, and the commander was forced to commit suicide. By the early 1970s, the patriotic armed forces had grown to more than 6,543.8+million, controlling more than two-thirds of Guinea-Bissau's territory and more than half of its population, and their activities expanded to the periphery of Bissau, the center of colonial rule.
In the second half of 1960s, Mozambique's anti-colonial armed forces established relatively stable base areas in Cape delgado and Nyasa, also carried out guerrilla activities in Mozambique and Zambezi River, and opened up a new battlefield in Tete. 1970 in may, the colonial authorities assembled 35,000 troops, used15,000 tons of military supplies, and also dispatched the navy, air force and special forces to launch large-scale attacks on the liberated areas such as Cape delgado, Niassa and Tete. After more than three months of bloody fighting, Mozambican patriotic soldiers and civilians wiped out more than 400 enemy troops, blew up dozens of enemy vehicles and shot down four enemy planes, which not only shattered the enemy's attack and consolidated the liberated areas, but also took advantage of the emptiness behind the enemy lines to push southward and further expanded the liberated areas.
1970 In the second half of the year, the Mozambican Patriotic Armed Forces continued to attack the Portuguese colonial army. 1970, 1 1-1971,1/years, patriotic armed forces carried out guerrilla warfare hundreds of times, killing and injuring more than 2,000 enemies. 1in July, 972, guerrillas opened a new front in Manica-Sofala. 1972-1September 1973, patriotic armed forces annihilated more than 2,300 enemy troops, shot down and destroyed 49 enemy planes, sank ships 1 1 and destroyed military vehicles. By 1974, the armed forces of MOLF had also grown to tens of thousands, controlling more than14 of the country, with a population of more than10 million.
