Look closely at the photos and notice the tusk poking out the other side of the buffalo.

Apparently the buffalo (the writer says "he" but it's obviously a cow) was sleeping in some bushes when an Elephant cow with calves came walking by and thus it was a case of being in the wrong place at the wrong time.

Awesome photos.
