Shakespeare’s Henry V shapes popular consciousness of England/Britain at war, yet resists accusations of jingoism. Its national imagining involves conscientious doubts about the justice of war itself. Chapter 5 shows that this appealingly inward, conscientious dimension of English national identity on stage is predicated on Scotland’s occlusion. Scotland was a major player in the Hundred Years’ War. Henry IV kidnapped the child heir to the Scots throne, James I. Henry V then forced James to fight his subjects, the Scots, in France. Yet Shakespeare carefully avoids acknowledging Scotland as a kingdom. He develops, from earlier history plays, a metaphorical plot that produces the idea of England’s island integrity as an effect of its king’s chaste reformation. In this plot, England is threatened by the wild incontinence of its royal heir until his reformation effectively secures England’s insularity, enabling English advancement ‘beyond sea’ to France. The analogy between royal self-chastening and English insular sea-power is traced through Greene’s Bacon and Bungay, Marlowe’s Edward II, the anonymous Edward III to Henry IV 1 & 2 and Henry V.
