well in the fourth apprentice no thunderclan cat died,but rippletail of riverclan did at the battle of the beavers.
Russetfur, Longtail, Rippletail, Flametail, and Swoop. (Firestar loses a life, but doesn't die completely.)
Feathertail, a silver she-cat from RiverClan, was killed by a falling rock while trying to save her brother from a collapsing cave near a riverbank where fish were abundant.
Spoiler! The story ends with Lionblaze saying the battle is real and it's coming. We must prepare. Or something like that. SummaryDovepaw learns she's the One. Lionblaze, Dovepaw, Tigerheart, Toadfoot, Petalfur, Rippletail, Sedgewhisker and Whitetail go on a journey to free the water. They suceed finding beavers but in the process Rippletail is killed. Sorry for the short summary!
He doesn't die.
As of the warriors book Sunrise, Hazeltail has not yet died.
Dovepaw and Lionblaze from ThunderClan, Rippletail and Petalfur from RiverClan, Toadfoot and Tigerheart from ShadowClan, and Whitetail and Sedgewhisker from WindClan went to find the beavers that Dovepaw sensed. They went to find the beavers because of a drought.
