The tabletop rules are adapted from the medieval rules in Neil Thomas's book Ancient and Medieval Warfare (AMW). I highly recommend this book to you.
AMW rules are based around units of 4 stands. I didn't have enough figures to use this size of unit as my armies are based for DBA and my available playing area small. My figures are 1/72 plastic and are based on a 60mm frontage.
However I came across a cut down version of AMW called Mini-AMW on John's Wargame Page blog. In these rules each unit is represented by a single base. That was perfect. Here are the Mini-AWW rules I used with some additional tweaks:
* Scythed chariots and Elephants are relevant to the ancient period rules but are not used in this medieval campaign. I have kept the artillery rule as there is a small possibility artillery may play a part in the campaign.
I use a causality marker to show stand causalities. These were constructed from a small square with pebbles glued on to each side to indicate causality numbers. The relevant number of causalities could be indicated by the side that touched the stand.
UPDATE
The causality stands didn't really work. I either forgot to move them or bumped them. So instead I purchased online a packet containing a lot of "Transparent Green Mini 5mm 6 Sided D6" dice. I just place a die on a stand with the number of casualties showing on the upward face.
In the standard AMW game both sides have a size of 8 units each. Now in an campaign you will mostly get unequal sized battles. So where possible when there was a contact in the campaign I would scale the smaller force up to 8 units and the larger force proportionally. Loss of battle occurs when a side reaches 1/4 of its original size.
Neil Thomas's Ancient and Medieval Warfare rules add chrome by having special rules for each army. These are the rules I used.
Saracen Heavy Cavalry enjoy these benefits:
Medieval Infantry:
In addition my rule is that Turcopoles are treated the same as Saracen Heavy Cavalry above.
In the campaign random tables were set up in Berthier to generate these choices.
Post-battle causality recover i.e. how to convert battlefield losses back to campaign losses, was kept very simple.
Victors
Each stand lost results in 25 men removed from the campaign unit - if the campaign unit does not move next move.
Otherwise each stand lost results in 50 men removed from the campaign unit.
Vanquished
Each stand lost results in 50 men removed from the campaign unit.
Drawn or Inconclusive
Each stand lost results in 25 men removed from the campaign unit.
