Holinshed's Fourth Booke of the Historie of England opens with the Roman general Plautius struggling to flush Britons from their 'lurking holes and couerts.' The narrative immediately foregrounds tactical detail: German auxiliaries swim a river to disable British chariot horses, and Vespasian—later emperor—leads a crossing that slaughters many enemies. This is not a summary of events but a close, source-driven chronicle that names commanders, cites classical authors like Dion Cassius and Eutropius, and records the exact number of days Severus reigned. The catalog subject 'Roman period, 55 B.C.–449 A.D.' is accurate, but the excerpts reveal a text more concerned with military maneuvers and dynastic violence than with cultural or administrative history.

Military Tactics and Roman Discipline

The excerpts repeatedly emphasize how Roman commanders adapt to British terrain and fighting styles. Plautius deploys Germans 'vsed to swim ouer riuers' to surprise the Britons, whose chariot horses are hamstrung. Later, the battle hangs in doubt until Caius Sidius Geta, though not a consul, earns 'triumphant honors' for rallying his troops. Holinshed records these details with a chronicler's precision, noting the exact river where the Britons withdraw—the Thames near its mouth—and the subsequent flight. The text treats each engagement as a set piece, naming officers and their actions, which suggests a reliance on Roman sources that valorize individual commanders.

Severus's Scottish Campaign and the Wall

Emperor Severus's response to British rebellion is notably brutal: he orders soldiers to 'kill all such as they might méet within anie place without respect,' a command Holinshed quotes in Latin from Homer. The narrative then pivots to the construction of a defensive wall, described not as stone but as 'turfe and earth supported with stakes and piles of wood,' with towers spaced so closely that trumpet signals could pass between them. Holinshed attributes this wall variously to Severus or Adrian, citing Beda and Hector Boetius. The ethnographic aside that the rebels were likely Picts, who 'wasted and destroyed the borders,' shows the chronicler weaving together classical authorities to explain Roman strategy.

Dynastic Strife and the Death of Severus

Severus's death at York is framed as much by grief over his son Antoninus's treachery as by illness. Holinshed records that Antoninus 'practised with physicians' to hasten his father's end, and after Severus's death, he murders his brother Geta 'euen in his mothers lap.' The chronicle gives precise dates—Severus died 'the third daie before the nones of Februarie' after ruling 17 years, 8 months, and 33 days—and follows the narrative to Antoninus's own death at Edessa. This section illustrates how Holinshed interleaves military history with personal and political intrigue, drawing on Herodian and Dion Cassius to construct a moral tale of ambition punished.

Readers should note that these excerpts represent only a fraction of the Fourth Booke, which covers the entire Roman period. Holinshed's method—compiling and sometimes juxtaposing multiple classical sources—means that contradictory accounts may appear. The catalog subject 'Great Britain -- History -- Roman period' is apt, but the text is less a modern history than a Renaissance compilation, rich with quoted speeches, etymological notes, and moral commentary. Approach it as a window into how Elizabethan chroniclers understood Rome's presence in Britain.
