You like Dutch. He's a charming fellow. He makes sense. He's like one of those nature writers from back East. Only he gets things a tiny little step too far. Rather than just loving the flowers and the animals and the harmony between man and beast, he shoots people in the head for money. And disagreeing with him.
Edgar Ross, to John Marston

And You Will Know The Truth is the forty-seventh mission in Red Dead Redemption.

To view the mission tree, see:

Main article: Missions in Redemption/Tree


John Marston is denied seeing his family once again by Agent Ross. He explains that they need to "take care of Dutch Van Der Linde now", and Marston has to help. With the help of the American Army, they attack his gang and move on to Dutch's hideout.


Mission Prerequisites

Before this mission becomes available, the player must complete:

Mission Objectives

To complete this mission, the player must:

  • Use the Browning Gun to defend the army camp from the outlaw attack.
  • Gun down Dutch's men.
  • Destroy the dynamite-rigged wagon.

Mission Details

Marston will get on the armored car and man the Browning Gun. It's just a short drive up the road, to a camp right outside Blackwater. In a little while, Dutch's gang will attack the camp, but they'll be no match for you and your machine gun.

After taking out most of the men, they'll retreat, and the armored car will follow them. There will be multiple enemies throwing dynamite from behind rocks, but they'll be no real threat. A large cart with TNT will approach, but is easily destroyed if you shoot at it. Soon enough you'll reach a cutscene where your armored car is toppled by an explosion, which ends this mission and starts the next.

Mission Failure

The mission will fail if the player:

  • Assaults or kills Ross or Fordham.
  • Fires the Browning Gun in town.
  • Assaults or kills any soldier.
  • Kills any soldier's horse.
  • Allows the rigged stagecoach to pass.
  • Breaks the law.
  • Kills a dog.
  • Commits vandalism.
  • Assaults or kills townsfolk.
  • Dies.

Gold Medal Objectives

  • Fastest Time: 4:45
  • Shot Accuracy: 15%
  • Number of Headshots: 11



  • Judging by Ross' words, it can be inferred the armored car is an early design for the armored cars and eventually tanks that were used in World War I.
  • At the Army camp, the US flag being used is the current model instead of the flag that would have been flown at the time.
  • At the beginning of the level (in the cutscene) you can see a picture of what appears to be the Strange Man hung up in the stairs at the police station, just like in Beecher's Hope.
  • The title of the mission (and the one following) is most likely a reference to the Bible passage John 8:32 - "For you shall know the truth, and the truth shall set you free". This is also the motto of the CIA.
  • Ross' use of the army is illegal, but since Dutch's Gang attacked their camp the ensuing conflict becomes an official military search and destroy mission.
