Calling all armchair generals! Boudica's Last Stand.

[Nathan Ross]

The Colchester Archaeologist refers to earlier finds of evidence for cherries, elderberries, raspberries, plums and sloes.  If these came from securely dated...

Yes, good thinking! This page has plums, cherries and raspberries from August, elderberries not till September, all of them into October. Sloes, apparently, are traditonally harvested after the first frost, in October.

So if these fruits (and the grapes we mentioned before) were indeed from the Boudican layer, and were fresh and not preserved, then it's pushing the fall of the colony back into September/October...
