Official Historical Battles released with B.I. demo (but not B.I. itself)

I remember when I first got the Barbarian Invasions demo, there were a bunch of Historical battles released about the same time which we could use with the demo - these were not included in the BI expansion set itself (which only has 2 historical battles)...

where on the internet can these extra Official Historical Battles be found?

I can't even remember what battles they were specifically, does anyone know? - that may help in searching for them...

IIRC the BI demo contained only three historical battles: Baden Hill, Chalons and the tutorial. The other battles were made available by modders. Most if not all of them can be found here.

thank you.
