[2] In fact Warrington did receive patronage from the Duke of York, and it was later said he lost 40,000 pounds to George IV in a night of gambling, so he had some connections to the Royal Family, but to what extent is unknown.
[2] He wore the unusual costume of a "red coat with blue facings and collar, richly embroidered in gold, French epaulets, and a cocked hat profusely decorated with ostrich feathers.
It was described as a "splendid horticultural development, containing the choicest fruit-trees of North Africa, with ornamental trees of every shape, hue ... the spot, in the middle of a waste, is now the fairest, loveliest garden in Tripoli.
[2] At a time when British influence on the Barbary Coast was overshadowed by that of France, Hanmer Warrington nevertheless succeeded in developing a close relationship with the local ruler, known as the bashaw, Yusuf Karamanli.
Due to the unpredictable nature of the tribal groups likely to be encountered, particularly the Tuareg, it was essential to obtain some measure of protection from the bashaw, at least as far south as his influence would reach.
Warrington was able to convince the bashaw to give his permission for the expedition and enabled the explorers to accompany a caravan leaving in the general direction of Timbuktu.
In 1822, Walter Oudney, Hugh Clapperton and Dixon Denham set out after much delay, once again with the help of Warrington who was able to convince a now doubtful bashaw that he should provide an armed escort.
