Calling all armchair generals! Boudica's Last Stand.

I can go with a composite force strength of about 5-6k troops being pretty much what he had available immediately.  Going north from London through hostile land that he has just marched through no doubt taking casualties as he goes does not seem a logical route to me unless the Britons are sacking London giving him a few days of relatively light opposition for manoeuvre.  So he would need to distance himself from London perhaps west for some distance then north.  Unfortunately I don't have a period map of Roman roads here to see available routes. Though he may have been able to march cross country as we are not talking huge distances. 
I am at our seaside caravan with a weak internet connection via mobile phone and away from my books.
Anyway - fascinating stuff, thanks!
