I just got a picture of Jacob Kiesel headstone in Manti & was hoping someone could help me with some military history on him?

Inscription, Manti Cemetery:
J Jacob Kiesel
2nd Lieutenant Company B 2nd Battalion 2nd Regiment Infantry
Utah Territory Militia
Indian Wars
April 10 1819 Febuary 26 1894

I have not done any military research, so I'm not sure where to start.
