A Mohammedan trader met Frederick Bailey (of the Bailey–Morshead exploration of the Tsangpo Gorge) in 1913 when he was robbed of all his money. He also met Kingdon-Ward, Lord Cawdor, Frank Ludlow and George Sherriff.
Frank Ludlow writes in the Himalayan Journal:
Abba Ulla [Atta Ullah] befriended Bailey in 1913 when he was robbed of all his money on his journey up the Tsangpo with Morshead. The old trader produced Bailey's letter of recommendation for our inspection & seemed very proud of it. He also showed us a letter from K. W. & Cawdor written in April 1924.
