Dear All,
Many thanks for your appreciative comments. I'm very pleased you liked it. I'll try to answer some of the questions you've posed...
... I am curious about the ranges you have for thrown spears, arrows from the longbowmen and crossbows. And of course the cannon.
On the cannon, do you use bounce through or just fire the cannon and see who it hits?
I don't remember exactly what the ranges are, but I think the maximum range for the longbows and cannon is about 1.5 metres. This is based on a piece of string which I marked to give six divisions of 25cm each. I don't use thrown spears, but now that you mention it...
For the cannon, as with the archers, I roll a six-sided die, rather than actually shoot cannon balls. My references to cannon balls bouncing or falling short or whatever was for 'narrative effect,' not a description of what I was actually doing. What really happened was that I roll dice to see whether the cannon would hit. When the roll was unsuccessful, I described in the narrative an explanation of what would have happened in 'real life.'
Just a thought... How many klickies were on each side and how many casualties each side had?

Waltheof started with 212 men, Aubrey, Wulfmaer and Remigius with 196. I can't remember the exact number of casualties, but suffice to say Waltheof's army came off very much the worse. Aubrey, Wulfmaer and Remigius lost about 60 men, I think. If you count men who fled the field and those who were captured at the end, Waltheof lost more than 100 men, if I recall correctly.
It seemed like an even larger and thus longer and more exciting engagement than you first battle...
Yes, definitely. Each side had about 25-30 more men than in the first battle I posted. Given the amount of room I've got (in the house, at least), around 200 men on each side is the most I can reasonably handle.
With such detail, that it was almost 'live'!! 
I'm guessing that you don't have any kids running around wanting to assist with the battle.. hehe.. I AM curious to the rules and how the dice fit which determined the outcome.
Thanks! I took pictures after every turn, so what I posted was pretty much how it happened, as it happened.
Actually, I think there was someone watching the thread as I posted it -- every time I would add a new post, I could see that someone (it wasn't me!) had just looked at the pictures attached to the previous post.
No, you're right: no kids to, ahem, assist! At least not yet...
I will try to write down the rules, but for the moment, suffice to say the dice do affect many things: do archers (or cannon) hit, whom does an arrow/bolt/cannonball hit, does a melee attacker hit, what happens if someone is hit (dead or badly wounded? wounded but still able to fight? no effect?), what happens when a unit 'checks morale' (fight on as normal? thrown into confusion? panic and run? if confused or fleeing, can their leader rally them?). I think that's it.
I do all this with dice to ensure a level of randomness, mainly because I'm in charge of both sides (I don't know anyone in my area interested in medieval wargaming with Playmobil), so, as I said in the account of my first battle, it's hard for me to surprise the opposing general!
Cheers,
AndrewL
