Portuguese Mozambique was the last territory to start the war of liberation. Its nationalist movement was led by the Marxist-Leninist Liberation Front of Mozambique (FRELIMO), which carried out the first attack against Portuguese targets on September 24, 1964, in Chai, province of Cabo Delgado. The fighting later spread to Niassa, Tete at the centre of the country. A report from Battalion No. 558 of the Portuguese army makes references to violent actions, also in Cabo Delgado, on August 21, 1964. On November 16 of the same year, the Portuguese troops suffered their first losses fighting in the north of the country, in the region of Xilama. By this time, the size of the guerrilla movement had substantially increased; this, along with the low numbers of Portuguese troops and colonists, allowed a steady increase in FRELIMO's strength. It quickly started moving south in the direction of Meponda and Mandimba, linking to Tete with the aid of Malawi.
