I want to know the answer to the following question:
When did George Bogle come to Shigatse to investigate prospects of trade.
All the background I'm provided with is that "The British Empire was encroaching from northern India into the Himalayas, the Emirate of Afghanistan and the Russian Empire were expanding into Central Asia and each power became suspicious of the others' intentions in Tibet.". Is that enough to answer the question?
Answer: no
