During the first war with Tibet, c. 1627, Portuguese Jesuits Estêvão Cacella and João Cabral were the first recorded Europeans to visit Bhutan on their way to Tibet. They met with Ngawang Namgyal, presented him with firearms, gunpowder and a telescope, and offered him their services in the war against Tibet, but the Zhabdrung declined the offer. After a stay of nearly eight months Cacella wrote a long letter from the Chagri Monastery reporting the travel. This is a rare report of the Zhabdrung remaining.
