I want to know the answer to the following question:
When did the war end?
All the background I'm provided with is that "With his primary heir dead, Henry rearranged the plans for the succession: Richard was to be made King of England, albeit without any actual power until the death of his father; Geoffrey would retain Brittany; and John would now become the Duke of Aquitaine in place of Richard.". Is that enough to answer the question?
Answer: no
