A Book or Two to Review (24): The Wars of Justinian I

The review frames Justinian's conquests through an emperor who kept political control while generals such as Belisarius and Narses led armies.

The book uses narrative histories and legislation to question familiar claims about cavalry, local troops, and supposedly non-Roman armies.

The review maps Justinian's forces across Constantinople, the eastern frontier, Africa, Italy, and Spain, showing how commands followed geography and operations.

An older official list reveals the army's inherited framework, but Justinian's new units and their distant deployments show why it cannot be read as a fixed sixth-century order of battle.

The distinction between mobile comitatenses and locally based frontier troops persisted, even when units and their privileges changed.

Land grants and uneven pay do not prove that frontier troops lacked military value; they formed the first line of a defence supported by regional reserves.

Non-Roman contingents were important but not automatically the army's dominant or most effective troops; their service and command arrangements changed over time.

The review recommends the book because it presents a complicated subject without reducing it to easy historical answers.

A reflection on allied operations explains why differing command structures, rules of engagement, and political aims complicate coalition warfare.
