The first two items deal with white-tailed deer and fencing (not fighting with swords), but the last item does show fighting, but in play.
Fences can serve a number of different purposes, but one of them is to keep domestic animals confined. Another is to prevent wildlife from accessing a region. The first two pictures suggest that these fences have questionable wildlife functionality.

A male white-tailed deer climbs under a simple rail fence, but the fence confines horses.

Here are three whitetail spikehorns (1½ years old). Two of them are play fighting and one has his head down. Male whitetails always seem to fight antler to antler. This is quite unlike the female whitetails shown earlier who stood up and brandished their forelimbs.

Oh, give me land, lots of land under starry skies above
Don’t fence me in
Let me ride through the wide open country that I love
Don’t fence me in – Cole Porter
