History of the Liverpool Privateers and Letters of Marque, with an Account of the Liverpool Slave Trade, 1744-1812

By 1783 three ports in England - London, Bristol, and Liverpool - accounted for over sixty per cent of privateering commissions.

The material Gomer Williams collected on Liverpool - drawn from newspapers and private correspondence and including numerous stories, assessments about the slave traffic, appendices, and indexes - is still considered to be the best source of information on privateering and the slave trade, from Liverpool or any other port.

Gomer Williams worked as a journalist for the Liverpool Mercury.
