The latest issue of wargames Illustrated is themed around Hastings and the English resistance afterwards. The first article is a refight of Hastings using 10mm figs but from Kallistra rather than Pendraken :o The text is just a run through if the game but the accompanying piccies are quiet nice and show what a spectacle can be achieved with 10mm. You really get the impression of two armies facing each other rather than just a few small groups of models looking more like an overgrown diorama.
If you'rer interested in 1066 and all that it's worth a look :)
Seconded. 10 mils en masse - you can't beat it. :)
