I’ve seen the first programme now. Sobering stuff. I think it’s the tentacles of slavery that astounded me the most. I wanted to find out more and Googled it. We used to live in an area of Scotland that was well-known for having had many cotton and linen works. The cotton came via Glasgow from the colonies and the linen was made into Osnaburg cloth, a coarse material used to clothe slaves. Even so, the clothes still belonged to the owner and could be removed as punishment, forcing the slave to be humiliated by having to work naked.
When I lived in West Africa I visited a former slave trading post. It had a melancholic air to it, with its wall and a gate with something like ‘the point of no return‘ inscribed above it. We heard that the captives were given a drink, presumably alcohol, and told it would make them forget about their former lives, which enabled the traders to herd them through the surf and onto the ships waiting on the other side of the lagoon.
