...and because of the nature of the story, we know practically nothing about the battle except that it was the one where Yoda used a chaingun.
Even crazier is the fact that he hauls the thing around under his own power.
This was, of course, brought to us as part of a tie-in to the Clone Wars shorts, the Clone Wars Adventures. (In the same tie-in, Jedi Aayla Secura had to carry around a quadriplegic, by which I mean dismembered, battle droid to translate Ewok talk. It was that kind of series. [And don't ask how the battle droid knew Ewok. It doesn't matter.])
