I remember at least 5 years ago on some public television station I saw an animated short that I'm almost certain was named Swamp. From what I remember it looked like stop-motion with paper cutouts or shadows. It focused around a battle between slender dark figures on horseback, there was a hot-air balloon involved at one point and I think both sides lost. I'm pretty sure it was almost entirely silent besides a few sound effects. I have grasps of what it looked like in my head, but I just can't remember anything else about it.

I really would like to see it again, so if anyone else can tell me any other information for it I'd be quite grateful.

This short was featured in an anthology collection called "The Animation Show of Shows, Volume 7". The short was directed by Gil Alkabetz and created in 1991.
