How do I complete the "The Course of True Love" mission without failing?

The Course of True Love is a main story mission in Red Dead Redemption 2 that involves helping Penelope Braithwaite and Beau Gray escape their feuding families. To complete this mission without failing, you must carefully follow the objectives and avoid common pitfalls. The mission begins in Rhodes, where you meet Penelope and Beau at the post office. Your primary goal is to escort them safely to the train station while avoiding detection by their families.\n\nFirst, ensure you have a reliable horse and a weapon equipped, as you may encounter enemies during the mission. When you arrive at the post office, interact with Penelope and Beau to initiate the mission. They will explain their plan to escape by train, and you will need to help them avoid being caught by the Braithwaites and Grays. Pay close attention to the dialogue, as it provides important context for the mission.\n\nAfter the conversation, you will need to escort Penelope and Beau to the train station. Follow the waypoint on your map, but be cautious of enemies patrolling the area. Stick to the main roads to avoid unnecessary confrontations, but keep an eye out for ambushes. If you encounter enemies, use cover and aim for headshots to dispatch them quickly. Avoid using explosives or fire, as they can harm Penelope and Beau, leading to mission failure.\n\nOnce you reach the train station, you will need to purchase tickets for Penelope and Beau. Approach the ticket counter and interact with the clerk to buy the tickets. Make sure you have enough money (around $10) to cover the cost. If you don''t have enough, you can sell items or loot enemies to gather the required funds. After purchasing the tickets, return to Penelope and Beau to hand them over.\n\nAt this point, the mission becomes more challenging, as the Braithwaites and Grays will arrive to stop the couple. You must defend Penelope and Beau while they board the train. Use the environment to your advantage, taking cover behind crates and walls. Focus on eliminating enemies quickly, but prioritize protecting the couple. If Penelope or Beau is injured or killed, the mission will fail.\n\nOnce the train arrives, help Penelope and Beau board it. Stay close to them and continue defending against incoming enemies. After they are safely on the train, the mission will conclude. Be sure to loot any enemies you defeated for valuable items and ammunition. This mission rewards you with honor points and progresses the story, so take your time and follow the steps carefully to ensure success.\n\nPractical tips for this mission include saving your game before starting, as it allows you to retry if something goes wrong. Additionally, stock up on health tonics and ammunition beforehand to prepare for the combat sections. If you''re struggling with the enemies, consider using Dead Eye to target multiple foes quickly. Finally, stay close to Penelope and Beau at all times to ensure their safety and avoid mission failure.
