I found I had 4 barded knights, 3 mounted armoured men at arms and 15 bowmen. To boost these up I ordered a pack of 5 knight, King and General and a wizard figures from Pendraken at the same time I ordered my Dark Elves and Lizardmen.
Together I was able to create the following force;-
1 x King Arthur (Hero General) @4AP
1 x Lancelot (Hero) @ 4AP
1 x Merlin (Magician) @4AP
4 x Knights of the Round Table (Knights) @8AP
2 x Bowmen (Shooters) @4AP
With an extra base of Shooters left over!
