Problem:Question: What was the name of the Ottoman governor who presented Robert Rollo Gillespie with an Arabian horse? Passage:He then transferred to India, traveling initially to Hamburg where, though both were in disguise and had no political principles in common, he was warned by Napper Tandy to flee to Danish territory in Altona. He continued overland through Germany, Austria, and Serbia, to the Euxine where he felt obliged to force his ship's captain at gunpoint to take him to Constantinople as agreed, rather than a corsair port for murder or slavery. He passed through Greece without recorded incidents, and took ship for Aleppo. He narrowly saved his own life, and his servant's, in the desert by curing the chief of a band of Arabs, who were planning to murder and rob him. He stayed for some time in Baghdad, where he was presented with a valuable Arabian horse by the Ottoman governor. From Basra he took ship for Bombay, then travelled overland to Madras. He was soon appointed to the command of the 19th Dragoons at Arcot, some 16 miles from Vellore.
