Calling all armchair generals! Boudica's Last Stand.

[Nathan Ross]

Again, you fail to understand the Roman psychology: "women are not rulers ...and those who pretend to be ... should be treated like Boudica was".

Leaving your view of 'Roman psychology' aside, the limited sources we have on Cartimandua make it clear she was a Roman ally and was not 'treated like Boudica'. Anything beyond that is your own imagination!

And anyone suggesting that the friends of Romans are in the north so that is where they would head ...

St Albans is to the north of London (21 miles north of it) - it is not in the north. It was a municipium, so the people there were certainly 'friends of Romans'.

But even five miles a day is a bit ambitious on campaign. More like 2-3miles a day.

Surely you are joking now? Perhaps you have been all along... Anyway, this merits no further discussion so I will be happy to drop it.

the most obvious is the valley taken by the old Didcot-Compton railway which would locate the battle at this point: Battle Site... she'd have had an extremely difficult time getting through these hills.

It appears to be an interesting site on the map. We might guess that Boudica and co had headed north-west through the Chilterns via High Wycombe or Tring and taken the old Iknield Way south-west to try and outflank the Romans in Silchester, then crossed the river at Wallingford and moved further west, perhaps with Suetonius retreating ahead of them and drawing them south into the 'defile' below Blewbury Down.

That might work, although it does require considerable long distance logistics and strategic planning on the part of the Britons. Why an East-Anglian tribal confederation would trek all that way (60-70 miles from London) just to fight a battle on ground of their enemy's choosing seems a mystery...

Google Maps has a useful drone view of the area, taken from a point just south-west of Churn Farm. It looks to be fairly open gentle country, not the sort of elevation that would daunt Britons who had already crossed the Chilterns and the Thames! This view from ground level on the track of the old railway (I think) does not suggest any more formidible terrain.
