This passage makes us think of the story of an African slave for several reasons:
First, the fact that the person was kidnapped ("two men and a woman got over our walls, and in a moment seized us both, and, without giving us time to cry out, or make resistance, they stopped our mouths, and ran off with us into the nearest wood"). While kidnappings occur all over the world in various circumstances, the slave trade used them systematically in order to separate families and capture people that could be sold as slaves.
Also, slaves were often forced to walk long distances after being captured ("The next morning we left the house, and continued travelling all the day") because they had to get from their native region to the coast, where they could board ships to Europe and America.
Finally, the fact that he sees people at the end of his journey, but they do not help him makes us think that the practice is normalized, which was the case with slavery ("I began to cry out for their assistance; but my cries had no other effect than to make them tie me faster and stop my mouth").
