30th, yes, the "X-files", episode 4x05, 4th season, episode 5: "The field where I died". Mulder discovers that he was a Confederate soldier in a previous life, and was killed in battle. [Edit: This is the only episode that deals with events in the Civil War, and also, I believe, the only one where Mulder (David Duchovny) actually cries real tears, for an extended length of time, remarkable for Mulder and the time elapsed.]
Congrats on your promotion.
