As You Like It Needs More Battle Scenes

First spotted on Reddit with the title "Pupils at Howell's Girls' School in Denbigh, north Wales, perform Shakespeare's 'As You Like It' during the 1930s", apparently from this January 2013 news story.  But I only have one question.

What scene is this?

Since they are all dressed identically it's impossible to identify individual characters. I just can't figure out when during the play there is any sort of military clash of opposing forces at all?
