Random Table: Who Did This Thirty Years War Veteran Fight For?

What possible use could you have for a random table to determine which faction in the Thirty Years War a particularly NPC fought for? Heck, I don't know, but we're all gamers, here... If anyone can think of a way to use it, we can, right? 

Who did this Thirty Years War veteran fight for? (d8)
d8	Fought for...	For/Against HRE?	Notable engagement
1	Hesse-Kassel	Against	Siege of Dorsten (L) (1641)
2	Electoral Palatinate	Against	Siege of Heidelberg (L) (1622)
3	Brunswick-Lüneberg	Against	Battle of Höchst (L) (1622)
4	Catholic League (Mainz)	For	White Mountain to Battle of Lutter (W) (1620 - 1626)
5	Bavaria	For	Battle of Zusmarshausen (L) (1648)
6	Bernhardine Army (France, kind of)	Against	Rhine Campaign of 1638
7	Imperial Army (Personal to Emperor)	For	Battle of Tuttlingen (W) (1643)
8	Saxony (Sweden)	Against	Battle of Lützen (W) (1632)

Roll d8. The first column provides the faction that the NPC fought for. The second is informational, and states whether that faction was aligned for or against the Holy Roman Empire. The third provides a notable engagement or campaign the NPC fought in, and the associated date; if a specific battle is listed, the outcome for the NPCs side (Won or Lost) is noted.

For some real fun, roll more than once. If the result indicates that the NPC fought both for and against the Holy Roman Empire, don't worry... this happened all the time, historically.
