Well, I have the Battle Reference Card scanned in and on my photobucket. Just in case GoG doesn't want it posted (as in the link gets removed), I'll post up the numbers as well.
-------------------------------------------------
Unit - Attack - Defense
Peasant - 1 - 0
Spear - 2 - 2
Archer - 1 - 0
Sword - 3 - 2
Mace - 3 - 1
Crossbow - 1 - 0
Axe - 4 - 1
Knight - 4 - 4
Notes:
1) The different abilities of unit types are reflected in the wages paid to maintain them after an army is raised.
2) When not in hand-to-hand combat, Archers and Crossbows are capable of ranged attacks. Archers can fire father than Crossbows, while Crossbows inflict more damage.

My photobucket for possible future scans of various need. I do have the tutorial booklet as well if I get around to it. 6.5MB total so no posting on here ,)
*EDIT*
Sorry about the spacing on the chart. GoG joins the many websites that don't like more than one space between words...
