When Lord Roger Reyne and his son Reynard rebelled against House Lannister and were defeated in battle, they retreated into the mines beneath Castamere. Tywin Lannister sealed every entrance with stone and earth, then dammed a nearby stream and diverted it into the mine, drowning everyone sheltering inside.
Cause
A deliberate act by Tywin Lannister, not an accident: after sealing all of the mine's entrances with stone, earth and soil, he ordered a nearby stream dammed and its flow diverted into the nearest entrance, flooding the workings.
What happened
Lannister men stationed at the most distant entrances reported hearing faint screaming and shouting from within the flooded mine; by daybreak, there was silence. The event became infamous across Westeros and was memorialised — some say composed by Tywin's own order — as 'The Rains of Castamere,' a song used ever after as an open threat by House Lannister against any who might consider rebellion.
Aftermath
No trial or inquiry is depicted; the flooding was itself Tywin Lannister's chosen instrument of judgment against House Reyne, carried out with the Iron Throne's tacit approval. Neither the mine nor House Reyne's seat was ever reopened afterward.
