Laertes' followers are riled up just before Laertes confronts Claudius. The followers want Laertes to be King instead of Claudius. As predicted, Claudius' throne is now in jeopardy due to the lack of support he is now getting from the kingdom's citizens.
Laertes annoints his sword in order to poison Hamlet, however at somepoint in the match (after Laertes poisons Hamlet, but before Hamlet is killed by the poison), Laertes and Hamlet switch swords and Hamlet also poisons Laertes.
First, Laertes stabs Hamlet with it. Then Hamlet takes it from Laertes and stabs Laertes with it. Then Hamlet stabs Claudius with it before forcing the poisoned wine down Claudius' throat.
They both died, though Laertes died first. During the duel, Laertes cuts Hamlet with the sword that has poison on it, but when they accidently drop their swords they got mixed up and got each others sword. Hamlet then cuts Laertes with the sword that has poison on it.
"Aaargh", although that's not in the script. Just before that he says, "Exchange forgiveness with me, Noble Hamlet. Mine and my father's death come not upon thee nor thine on me."

Laertes is the father of Odysseus in the Iliad and the Odyssey. Laertes is also a character in the play Hamlet by William Shakespeare.
Laertes, in a parallel revenge, seeks revenge against Hamlet for killing his father, Polonius, and the early death of his sister Ophelia. Hamlet does die, but not before Laertes, so Laertes never does get his revenge against Hamlet
In Greek myth Laertes was king of Ithaca.
