Exodus in America

 is the very first mission in Red Dead Redemption.

Story
In the opening cinematic, John Marston exits a river boat in Blackwater with two federal lawmen (Edgar Ross and Archer Fordham). They are to ensure that John gets on the Blackwater Train headed to Armadillo. While on the train, he overhears the conversations of two old women, Mrs. Bush and Mrs. Ditkiss, as well as that of a preacher and his companion, an optimistic young missionary named Jenny.

Upon reaching Armadillo, a man named Jake (who has been hired by Edgar Ross) guides Marston to Fort Mercer. After reaching the fort, Jake leaves Marston alone to deal with Bill Williamson and his gang.

Mission Objectives
To complete this mission, the player must:
 * Find Jake in the Armadillo Saloon.
 * Accompany Jake to Fort Mercer.

Mission Details
When the train arrives, John then becomes playable. The player must go to the saloon of Armadillo, which is marked with a yellow X on the map. The player will be informed they can sprint by tapping on X (PS3) or A (Xbox 360). When you enter, a man named Jake calls to the player. He says he is hired by the police of Blackwater to serve as a guide to Fort Mercer where Bill Williamson apparently resides. He lends the player a horse, and together both head to Fort Mercer. Hold X (PS3) or A (Xbox 360) to match his horse's speed. When the player passes an animal corpse, pressing O (PS3) or B (Xbox 360) will zoom in on it.

When the player arrives, Jake parts ways with John., John then walks to the ominous gates of Fort Mercer where he shouts for Bill Williamson to show himself. After a while, Bill appears on the walls with two of his goons warning John to go away. John tries to convince Bill to come with him to jail or else the police will kill him. Bill refuses, saying that John never saved him, only himself. John implores Bill to come with him, but Bill laughs at him and says that he is in charge now. John tries to grab his revolver, but one of Bill's goons shoots him in the lower torso. He falls unconscious, and Bill and his goons walk away, leaving John to die.

The next morning, a young lady named Bonnie MacFarlane and a man named Amos appear. They see John wounded and take him away in their wagon to the doctor in Armadillo.

Trivia

 * The cutscene with John sitting in the train is also an introduction to the theme of the game; at one side, the conversation between Mrs. Bush and Mrs. Ditkiss is about old world facing change from a new world. The Old West in the game is being introduced to technology and civilization. The other conversation between Jenny and the preacher is about redemption and forgiveness which John is seeking; he is trying to leave his criminal life behind and make everything normal, which requires him to repay himself for what he's done.
 * When riding alongside Jake, he gives a brief history of Fort Mercer. During it, he says "maybe they [soldiers] got tired of being soldiers and went out hunting for gold?" This could be a homage to the plot of Battlefield: Bad Company, another video game, in which a squad of soldiers go AWOL in order to steal gold from a legion of mercenaries.
 * Bonnie MacFarlane was also present at the train arriving from Blackwater.
 * The train leaving Blackwater actually goes backwards as if going to Mason's Bridge, but the game flips it so the train goes the right way.
 * It is unknown why John was on a steamboat to Blackwater even though he lives in Beecher's Hope. It could be speculated that Marston was abducted along with his family and taken to another location that might require his being returned by boat.
 * Jenny, who was seen on the train, is later found in the wilderness during the Stranger side-mission &quot;Jenny's Faith&quot;.
 * Jake, the man that acts as a tour guide, is only present in this mission. It is unknown what happens to him afterwards.
 * The opening cinematic bears a close resemblance to the opening cinematic from GTA IV, also made by Rockstar, which shows the protagonist Niko Bellic getting off a boat, followed by a shot of a car being unloaded from the same boat.
 * Mrs. Bush and Mrs. Ditkiss, the ladies seen talking in the train, never appear again.
 * This is the only time in the entire game where there is a child seen (aside from Jack).
 * This is the only mission in the game where John gives himself the mission.
 * Shooting a cow while riding to Fort Mercer will cause you to fail the mission.
 * This is the only mission that the player can see more than one vehicle parked around Blackwater.
 * This is the only mission an active steamboat is shown.
 * When you approach the fort walls, there will be 4 birds on one of the taller walls. Scare them off by firing your gun. Shoot all 4 of them to unlock the Sharpshooter Challenges. (You can get the 5th a the MacFarlane's Ranch before you are shown around by Bonnie).
