The convoys were not meant as humanitarian aid, but as an attempt to support the local working class: In the middle of the war, the people in Tuzla refused to be incited against each other along their ethnicity.
Tuzla lies in a mining area with a long history of workers' resistance, reaching as far back as the miners' strike of 1922. During the Yugoslavian war this region was besieged from all sides in the attempt to destroy the multi-ethnic society of the region.
In 1984/85 the miners in the Tuzla region had donated one day's wage per month to the striking British miners. In 1992 there was a call for the British miners to return this solidarity. Thus began the story of the aid convoys to Tusla.
