The "Blood in the Water" match (in Hungarian Melbourne-i vérfürdő, "Blood Bath" of Melbourne) was a water polo match between Hungary and the USSR at the 1956 Melbourne Olympics. The match, which took place on December 6, 1956, was against the background of the 1956 Hungarian Revolution and saw Hungary defeat the USSR 4–0. The name was coined after Hungarian player Ervin Zádor emerged during the last two minutes with blood pouring from under his eye after being punched by Soviet player Valentin Prokopov. - Wikipedia
