"What had been a Quidditch match turned swiftly into a human versus tree battle, which the wizards won only after seven hours’ hard fighting. Nenad was not prosecuted as he had been killed early on by a particularly violent spruce." (Pm)
The final of the Quidditch World Cup in 1809 is considered to be one of the worst exhibitions of unsportsmanlike conduct in history.
The match between Romania and New Spain (now Mexico) ended in a massive attack by the forest near to the stadium on the edge of the West Siberian Plain which injured many and killed several. The forest had been bewitched by local Dark Wizards in the pay of one Niko Nenad, a hot-headed player who was known for violent outbursts, including attempts to strangle referees. The battle lasted for seven hours (Pm).
