Toon is right- there is one more battle report, but I think that's it for WM battles in WD.
Kind of sadly, I'm pretty sure WM coverage in White Dwarf ends with a 'looking forward in Warmaster' article, detailing all sorts of future plans and new models to come.
If I get a chance I'll look through my WDs and try and get more details for you- it'll take me until the 6th at the earliest.
