Nathaniel Watts was captured by Lieutenant-General William Keppel whilst working as an engineer in Cuba in order to deprive the Spanish of 'such an ingenious man'. On 6 June, 1763, William Keppel wrote to Charles, 2nd Earl of Egremont, Secretary of State for the South that Watts was 'an excellent mechanick [sic], and well acquainted with all parts of the mathematicks [sic]'. Records dated between 1766 and 1769 show Watts active as an engineer on the islands of Jamaica and Antigua. The present drawings shows that he was still active on Jamaica in 1786, twenty years later.
