Halbarad, a kinsman of Aragorn: Hal- I don't know the meaning of, and it is an uncommon word stem, unlike ara-. -Barad is tower, and Halbarad was a tall man (but so were the rest of the Dunedain). At any rate, Halbarad was the standard bearer of Aragorn in the Battle of the Pelennor Fields, and (presumably, since he led the Dunedain out of the north into Rohan) a leader of the Dunedain in Aragorn's absence. His eulogy described him as being 'dour-handed', which to me says that he was a mighty warrior, or a stern captain. His answer of the 'summons' of Aragorn (Aragorn's wish, not spoken word- see
'Passing of the Grey Company' ) bespeaks his foresight and wisdom. A loss to the Dunedain, but of course I'm biased.
