What happened in the last episode of Lost as i missed it?

Did they get rescued?

Season finale

[edit] Counterattack and rescue plans

Naomi tells everyone of the rescue freighter 80 miles offshore, and that her satellite phone is being jammed.

A three-part plan is devised:

* Jack will lead most of the survivors to the radio tower in order to shut off Rousseau’s S.O.S.

* Jin, Bernard, and Sayid will stay behind and kill the raiding party by detonating strategically-placed dynamite with gunfire

* Charlie and Desmond will go to the underwater Looking Glass station and shut off its jamming signal as well, though, according to a “flash” from Desmond, their mission’s success means Charlie will die.

Meanwhile, we find Locke still alive, re-paralyzed and about to shoot himself, when a vision of Walt tells Locke he can walk, and that he has work to do.

Jack and the tower-bound group are intercepted by Ben and Alex. Ben says Naomi is lying, and she will be the death of everyone on the island. Ben is taken captive, and Alex is introduced to Rousseau for the first time.

Charlie disables the jammer and speaks with Penelope via videophone -- she has no knowledge of Naomi. Mikhail, outside the station, detonates a hand grenade, causing Charlie to drown. Before dying, Charlie writes “Not Penny’s Boat” on his hand and shows it to Desmond.

Rousseau disables her S.O.S. call. Naomi reaches her ship via a satellite phone -- but is killed by a now-walking Locke, who tells Jack they are not meant to leave the island. Defiant, Jack speaks to the person on the phone, who says they will be there soon.
