Recent work by Professor Clare Anderson has established the extent of the horrors: in just one year, 1856-57, and on one route, Kolkata to Trinidad, the percentage of deaths of indentured labour on the transportee ships reached appalling levels: 12.3 per cent of all males, 18.5 per cent of the females, 28 per cent of the boys and 36 per cent of the girls perished, as did a tragic 55 per cent of all infants. To make an admittedly invidious comparison, the deaths of slaves on the notorious ‘Middle Passage’ was estimated at around 12.5 per cent.
