How is Oroonoko captured to be sold into slavery?

When Oroonoko is in Coramantien an English ship arrives, which is captained by a man that Oroonoko has sold slaves to in the past. The Captain invites Oroonoko aboard his ship for a banquet, along with at least one-hundred other guests. The banquet is a ruse, and all of the guests, including Oroonoko are seized and imprisoned. All of them have gone from guests to cargo without suspecting a thing.
