That was more of a big skirmish. In any case, up above, the suggestion was made that the battle was the taking of Orthanc by the Ents, which is only described, not shown, in the book.

For some reason, that is sticking in my mind--I would place my bet that the battle PJ is talking about is the Rohirrim attacking the orcs that had carried Merry and Pippin off. I seem to remember reading a spoiler that sounded like it would be that scene.
