Hi JB! I have had a pretty crazy school year, this time around, so am just seeing the later part of this thread. I hope you enjoyed your games of Song of Drums and Tomahawks. As a side note, the Beaver Wars supplement does include 18 scenarios that you could use for just about any period -- not just the Beaver Wars. Many could also be for tribal vs. settler or European, by simply changing the name of one side. They were meant to be relatively generic skirmish encounters typical of the Eastern Woodlands.
Feel free to comment or send a PM if you have questions. Would love to see some AARs, and I could even link them on the First Command Wargames website page.
