Last Debate
From Tolkien Gateway
The Last Debate, recounted in The Lord of the Rings chapter by the same name, was the council that Aragorn held with Imrahil, Gandalf, Éomer, Elladan, and Elrohir. It was held outside Minas Tirith on March 16, 3019, and there it was decided "that they should set forth on the second morning from that day with seven thousands [of men], if these might be found" (RotK p. 174)to fight Sauron in the Battle of the Morannon, in the hope that Frodo Baggins and Samwise Gamgee might finish the Quest of the Ring in Mordor.
