The museum's manuscript resources for researching impressment and press gangs are listed below under the eight manuscript sections used by the museum and give reference number, brief description and date. Fuller details can be found in the relevant section list, available in the Library.

The guide is intended to show the type of manuscripts held, rather than act as a comprehensive list. Researchers might, for instance, also consult individual lieutenants' logs (manuscript reference ADM/L/ series) for details of particular events. Logs can be traced by date and vessel name.

Impressment was the compulsory recruitment of men to the Navy by parties of seamen commanded by officers, known as a 'press gang'. It was legally based on the royal right to call all men for military service and later confirmed by many legal opinions. Impressment lasted until the end of the Napoleonic Wars because the administrative resources of the state could find no better way of providing men for the ships. After 1815, though not abolished, it was not used. Only seamen should have been pressed but in practice, as needs increased through the 18th century, all types of men were drawn in.
