Journey from India towards England,

'Jackson went to India on private business, visiting Ceylon and the Malabar coast while there. He travelled out by ship but took the overland route home. On 4 May 1797 he left Bombay by country ship for Basrah. He proceeded via the Euphrates and Tigris to Baghdad, and thence travelled through Kurdistan, Armorica, Anatolia, Bulgaria, Wallachia, and Transylvania, reaching Hamburg on 28 October of the same year. Under the title Journey from India towards England (1799) he published an account of his travels in which he showed that the use of the route he followed was practicable all the year round. Jackson's narrative of his journey is straightforward in style, with daily entries describing his party's progress, and observations on the people and places they encountered. Although he advocated greater use of the overland route, he conceded that it was only for the physically hardy, and his description made it that the route was potentially dangerous. He advised on how to seek help from the local people and how to travel inconspicuously. Jackson showed himself both curious and flexible in adopting local habits of dress, of wearing beard and moustache, and of eating, drinking, and smoking. The reviewer in the Gentleman's Magazine described the Journey warmly as 'a very useful and instructive guide' (1st ser, 70, 1800, 237–9).' (ODNB).
