The new Hussite list, written by chum Peter Anderson (thanks Peter!), is the first published list to include large numbers of war wagons. The Hussite Wars are fascinating and this really is an iconic list that we should have published years ago. You can find the 218th TtS! army list in the Later Medieval booklet.
The stunning war wagon above was painted by Gregory Blake, who tells me he has a dozen of them, lucky so-'n-so.
