Well, the ocean invaded Numenor, who you could say is the mother of Gondor. Technically it could happen again. Imagine, Aragorn takes revenge on the ocean for killing his distant relatives.
I love the "For Frodo" in the movie. They had just shot down a deal to save Frodo from a terrible fate, leaving him to certain doom, but they fought for him, for the small weakling willing to carry such a burden. Although you have to think of all the things going through their minds at that point. They hadn't heard any word from Frodo or Sam for ages. The mouth of Sauron presented Sam's sword, a grey cloak and Frodo's vest. You would have to wonder what happened that they got only one of their cloaks and Sam's sword and Frodo's vest, and just those things, without Frodo's sword or the Phial of Galadriel or anything. Although it's conceivable the orcs wouldn't touch some of their elvish things. And the mouth only mentioned one hobbit, which is telling. And the most important thing is that obviously Sauron doesn't have the ring. It would be obvious if he did, and the mouth didn't seem to have any idea why they sent a hobbit. Now, it doesn't make sense that Sauron has Frodo and doesn't have the ring. It's possible some orc tried to take it, like what happened with Merry and Pippin, but if Sauron's servants found it in Mordor it would definitely end with Sauron one way or another, even if the servant in question wanted it for themself. Really, if anyone else besides the hobbits had the ring, they would probably know. Because if someone started using the ring all powerfully, they would probably notice, and Sauron wouldn't bother with the whole Mouth of Sauron exchange. And if someone like Gollum got it, while in Mordor, Sauron would know immediately and would know Frodo's quest. So either Frodo or Sam must still have the ring, hidden from Sauron. Aragorn is aware that Sauron's a total liar. He knows that at least one of the Hobbits was captured, or at least seen and lost some of their possessions. Heck, it's possible neither of them were captured, they just had an incident with orcs and lost some of their stuff, and Sauron came up with the whole lie off the knowledge that there is a small person who entered Mordor. So I think Aragorn comes to the conclusion that Frodo is alive, or he's doomed and Sam has the ring, in which case they're fighting for Frodo's sacrifice. In any case Aragorn now knows that Sauron knows that there is a potential threat in Mordor, and Sauron is probably sending nightmares after the Ringbearer. So there's greater need for Aragorn's forces to attack and draw all the ringwraiths and other monsters away, because there is still hope, and it is their only hope. Aragorn doesn't try to argue with the Mouth of Sauron, because that would be pointless. These things were probably going through Gandalf's head to, but I talked about Aragorn because he's the one who said the line. One of the really cool things in the Lord of the Rings movies is how there's this sense of: this may be our last fight, but we will fight. Like the last march of the Ents. They are fully aware that it may be the LAST march. But they will fight, fight for the trees and will not be overrun and conquered one by one. And then you've got the Battle of Helmsdeep with the same vibes, but a new dawn comes and there is hope and they live to fight another day. With that last battle of the gates of Mordor, in the movie you can see, they are so freaking outnumbered. But they go and fight. If they all just stay in Minas Tirith, Sauron will eventually wear them down, their battle was dearly one and Sauron has endless forces. So they go and fight, fight for a small hope, a tiny force charging against an ocean. It is a hopeless fight, a fight they will not win. But then they ring is destroyed and it's a new dawn of hope and oh my gosh I love the Lord of the Rings. Sorry I have a lot to say about this.
"Surrounded and outnumbered a thousand to one, the armies of Men stood. In their darkest hour, on the brink of annihilation, the Last Army of Man did the unthinkable. They charged." -J.R.R Tolkien, The Battle of The Black Gate, The Return of the King
If by my life or death I can protect you, I will I give you my sword Ringbearer, I give you my word, It cannot be broken. Nor turned aside, Let the horns sound, This day is not done! Let Mordor know this: Elessar! Elessar! The Lords of Gondor have come
I usually don't cry at movies, because I know they aren't real, but Return of the King hit different. The acting, the lines, and the music. Only movie I have ever cried too.
