What if Wilburforce passed his law prohibiting neutral flags immediatly at the beginning of the nepolianic war? would there be a benefit to slavery ended slightly earlier?
It allowed privateers to board and seize from ships flying a neutral flag.
It was described as a way to stop French shipping as they often flew the American flag to avoid seizure. However, a huge amount of british slavers also flew the American flag. Since privateers wouldn't care where they were getting they're money they also raided the British slavers.
Seems a good way to start a war. Perhaps this starts an earlier 1812 style war? Or maybe it just behooves the US to start building a navy sooner to defend ships flying its flag.
