Calling all armchair generals! Boudica's Last Stand.

[Nathan Ross]

The size of London in 55AD is shown as about 550x250m by Dominic Perring or 14 hectares

Wrong again, I'm afraid. This is page 87 of Perring's London in the Roman World, 2022:

   

As you can see, London at the time was between 39 and 60 hectares, with a population of 10-15 thousand, and was 'Britain's most important town in AD60'.

This is according to the very historian you have just cited.

Anyway, it appears we have radically different views on all this, and any further debate will be a waste of time, so I shall leave things here.
