Not perhaps one of his better known works, for all that as good as most. This covers the period before the lands that became India were incorporated by the East India Company, when adventurers were making fortunes in all sorts of ways.
The European mercenaries were really of huge import in this period, and the Maharattas (who had effectively replaced the Moghuls by that time) depended on them rather than their mobs of irregulars.
The Duke of Wellington (as he was to be) made his name at the Battle of Assaye (1805) against them (or what was left after the diplomats bought out the European officers). The achievements of these adventurers were remarkable and make a rollicking tale. Of course, Shipway's own career as a cavalryman in India, lends enormous detail and authenticity to the story: Wonderful stuff for young and adult alike..... though a bit bloody (authentic) for the under 10-12s perhaps.
