Calling all armchair generals! Boudica's Last Stand.

[Nathan Ross]

Will Bowen presented a map of Iceni-ish territory, placing that territory 1.6 miles from Thrapston, his map, his choice of definition. (BFT 2023)

Hmm, it seems suspicious that the border of 'Iceni territory' exactly matches that of the modern county of Cambridgeshire, established in 1972...

Before that the bit shown on your map was part of Huntingdonshire, I believe. Chatteris seems to be westernmost place that shows signs of Iceni influence. In any case, the Romans would want to attack the heartland, as you say, not the fringes - and it so happens that there is a road going directly there from Dunstable/Tring.

But anyway, yes, I now shall retreat to my defile and keep my head down!
