COREMO were a Chinese supported splinter group of FRELIMO formed in mid-1965 in Lusaka in Zambia (Abbott & Rodrigues, 1998; Morris, 1974). COREMO were big enough to put guerrilla forces into the field. Their bases were in Zambia; the main training base being Chipata. Their chosen area of operations was the Tete area and they had several staging posts along with Zambia-Mozambique border. They had 500 trained men of which 250-300 were in Mozambique at any one time.
