In 43 CE Vespasian, commanding Legio II Augusta in the Claudian invasion, fought in southern Britain and reduced towns and the Isle of Wight as later Suetonius tells it.

Context

Suetonius Vespasian 4 and Britannica independently print the British command under Claudius. Unique body counts are not invented. Claudius remains the emperor of the invasion.

Vespasian’s documented role is bounded by other offices and collaborators named in the sources below.

Conventional years are 9–79 CE. Surviving public files are later Suetonius, Tacitus, Josephus, coins, and encyclopedia pages. Vespasian did not typeset those later English pages. Dates here are received historical years.

Why it matters

Humanitarian-harm path via conquest. High confidence on the command as received; not a unique casualty table.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
