The journey to Tibet only served to whet Moorcroft's appetite for more extensive travel. But when he broached the idea of a new horse buying expedition to Bukhara in 1816, a searing reply from the EIC Board of Managers warned Moorcroft to keep "steady" at his stud duties and not "waste his time" on "wild and romantick ("sic") excursions to the banks of the Amoo (Oxus) and the plains of Chinese Tartary." What Moorcroft coveted most were the Turkoman horses, with their pale golden coats, narrow chests, long necks and sturdy legs. The "good Turcoman horses" that Marco Polo had described some 500 years earlier could travel a day for weeks on end. Their descendants, the Akhal-Teke, are bred to this day in Turkmenistan and Russia. Moorcroft persisted in his quest and his seven-year campaign was finally rewarded in May 1819 when Charles Metcalfe, head of the EIC's Political and Secret Department, granted him leave to proceed. Metcalfe's goal was to use his friend as an intelligence scout on his epic journey.
