This volume is a collection of a variety of important records that will give readers insight into key themes into the history of what its criminal code called “the unnatural and detestable sin of buggery”- sex between males - in the Royal Navy. The richest sources are transcripts of trials, including ones that erupted into public scandals and ones that provide a vivid window into the sexual cultures of the navy. The book also provides lists of important records in the naval archive and will serve as a guide to finding and interpreting them. This important volume, accompanied by extensive editorial commentary, opens up this history and archive to researchers, teachers, and students studying queer history, the history of gender and sexuality, and naval and maritime history.
