I want to know the answer to the following question:
John acquired key land between Poitou and where?
All the background I'm provided with is that "On the other hand, the Angoumois lands that came with Isabella were strategically vital to John: by marrying Isabella, John was acquiring a key land route between Poitou and Gascony, which significantly strengthened his grip on Aquitaine.[nb 5]". Is that enough to answer the question?
