Wainhouse. The men received a prompt reply from "Dr." Donald Belford, a former British Army medic who had volunteered for a humanitarian aid group in Africa some years before. While there, he had treated several Angolan fighters wounded in the struggle against the Portuguese, earning their friendship and trust. One of his friends was Holden Roberto, leader of the FNLA. After independence, Belford became Roberto's official emissary in the United Kingdom. Georgiou in Angola Georgiou was now using the nom de guerre "Colonel Tony Cullen" – the surname of a former army friend and not, as mistakenly alleged by some journalists, inspired by the TV espionage series Callan. He went to Angola to work as an unpaid medical orderly, in advance of his three colleagues. It was while he was working in this position that he took part in the decisive action that brought him to the notice of the FNLA leadership. When FNLA soldiers fled the advance of a MPLA force, which threatened to capture the hospital to which he was assigned, Georgiou, and longtime Irish colleague Lyndon Sheehan, led a handful of Portuguese FNLA soldiers in an offensive defence, stopping the MPLA force in its tracks. The general trend of the war for the FNLA at that time was one of a steady string of defeats, ensuring that the defeat of the MPLA column attracted immediate attention from Holden Roberto who, to Georgiou's surprise, appointed him head of the FNLA army, with the rank of Colonel (still unpaid). His three friends including Charlie Christodoulou arrived from Britain shortly afterwards. Within 48 hours of his arrival in Angola, Georgiou had already led his men in disarming and massacring a group of FNLA fighters (his supposed allies), who he killed just for the "fun" of it all.

This, combined with the foreign origin of most of the core leadership, (Georgiou, Christodoulou and the Portuguese), created a deep gulf between the officers and the British other ranks – to say nothing of the native Angolans recruited as infantry and support troops. Most of these had no military experience and many knew
