 The campaign had a significant effect on British cartography of the region . Wainwright reported that the available charts of the Persian Gulf were inaccurate or incomplete , thus allowing Al Qasimi ships to hide from his squadron in uncharted inlets . The Bombay Marine had long been aware of this problem and had been developing charts of the region in the years leading up to the campaign , under David Ewen Bartholomew , who had been on Sapphire during Corbet 's mission to the region and whose charts were published in 1810 as a response to these problems .
