I did some poking around online and came across an account of the Immortal Game between Adolf Anderssen and Lionel Kieseritzky in London in 1851, and was able to see the match played via animated GIF. It was better than nothing.
Kieseritzky was dominating the match, and he became so focused on acquiring pieces that he neglected to protect his king. Anderssen, meanwhile, went for position, and maneuvered with his lesser pieces. Though outgunned and seemingly exposed, Anderssen's king was able to maneuver; Kieseritzky brought out his big pieces early, which meant that his king was hemmed in by his pawn line -- and this cost him the match. Chess players still study the game; it is the stuff of exciting play.
Moral of the story? Perhaps it would be: take care of the King if you want to win.
Viva Cristo rey!
