In 1890 Younghusband was sent on a mission to Chinese Turkestan, accompanied by George Macartney as interpreter. He spent the winter in Kashgar, where he left Macartney as British consul. In 1891 he returned to India through the Pamirs. At Bozai Gumbaz in the Little Pamir he encountered Russian soldiers, who forced him to leave the area. This was one of the incidents which provoked the Hunza-Nagar Campaign. During his service in Kashmir, he wrote a book called 'Kashmir' at the request of Edward Molyneux. Younghusband's descriptions went hand in hand with his paintings of the Valley by Molyneux. In the book, Younghusband declared his immense admiration of the natural beauty of Kashmir and its history.
