I want to know the answer to the following question:
What was the last territory added to British India?
All the background I'm provided with is that "Relationships with neighbouring British territories then broke down, starting the First Anglo-Sikh War; this led to a British official being resident in Lahore and the annexation in 1849 of territory south of the Satluj to British India.". Is that enough to answer the question?
Answer: no
