Fram slays Scatha the Worm (estimated date)
Event Type: Military/Strategic
Age: 3rd Age - The Kings
[The songs of Rohan] ... tell that [Fram] slew Scatha, the great dragon of Ered Mithrin, and the land had peace from the long-worms afterwards. Thus Fram won great wealth, but was at feud with the Dwarves, who claimed the hoard of Scatha.
The Return of the King, LoTR Appendix A, Annals of the Kings and Rulers: The House of Eorl
Then Éowyn gave to Merry an ancient horn, small but cunningly wrought all of fair silver with a baldric of green....
'This is an heirloom of our house,' said Éowyn. 'It was made by the Dwarves, and came from the hoard of Scatha the Worm.'

[Note: the date is estimated, based upon the migration of the Éothéod in 1977 III, led by Frumgar, Fram's father.]
