Calling all armchair generals! Boudica's Last Stand.

Also, T mentions the reinforcements arriving from the Rhine before he says that Paulinus put his auxiliaries in new winter camps, implying they arrived during the same season as the battle, which as the seas close to shipping in late September would mean the battle was in midsummer...

I think that this needs to be qualified slightly. According to Vegetius (ERM, 4.39) from six days before the Kalends of June (i,e., 27 May) until 18 days before the Kalends of October (i.e., 14 September) the seas are safe. After that until three days before the Ides of November (i.e., 11 November) they are doubtful but still navigable. Thereafter the seas are closed until six days before the Ides of March (i.e., 10 March). This may not have much bearing on the date of the final battle but, if the seas were open until 11 November, this allows more time for all the events in the aftermath to take place, i.e., for Paulinus to carry out his campaign of retribution, for the reinforcements from the Continent to arrive, for Classicianus to be appointed to replace Catus, to travel to Britain, make his assessment of the effect of Paulinus' actions and to make his recommendations, and for Polyclitus and his entourage to travel to the province, investigate the situation and to return to Rome to present his report. It also suggests that Turpilianus could not have arrived in Britain to replace Paulinus before mid-March 62.
