Chapter 2 looks at seamen who were ‘aliens’ (non-subjects), and shows that legal distinctions ultimately mattered little to the Navy. Britain was rather open to immigration, and during wartime most residual disabilities of non-subjects were eased for common sailors, who were needed and overall welcome. At the same time, military necessity meant that any advantages which their status as subjects of a different sovereign should have afforded them, most notably protection from impressment (forced service), were often ignored in practice. In courts martial, special accommodations and concessions were granted informally, as a result of perceived cultural ignorance, rather than on the basis of legal status. Finally, naturalisation was liberally bestowed on naval seamen, but it was, this chapter argues, a largely irrelevant benefit. The state was very quick to revoke its protection if this clashed with native allegiances, and during wartime the alien sailor, already allowed to work in both the Navy and merchant vessels, did not stand to gain much from being naturalised. If individual seamen strategically navigated legal status and national allegiances, so did the state itself: when in need of manpower, it did not hesitate to treat its own legal categories and subjecthood boundaries as pliable.
