I want to know the answer to the following question:
Which french emperor gained possession of Longwood house and the land surrounding it?
All the background I'm provided with is that "In 1858, the French emperor Napoleon III successfully gained the possession, in the name of the French government, of Longwood House and the lands around it, last residence of Napoleon I (who died there in 1821).". Is that enough to answer the question?
Answer: yes
