How do I complete the "A Fisher of Men" fishing challenge in RDR2?

The ''A Fisher of Men'' fishing challenge in Red Dead Redemption 2 is part of the Stranger mission series involving Jeremy Gill, a fishing enthusiast. To complete this mission, you must catch and deliver a legendary fish, the Legendary Largemouth Bass. This mission becomes available in Chapter 3 after completing the main story mission ''The Course of True Love III.'' Jeremy Gill will send you a letter inviting you to meet him at his cabin near Flat Iron Lake, southeast of Rhodes.\n\nTo start the mission, head to Jeremy Gill''s cabin, marked by a fishing icon on your map. Speak to him, and he will explain his passion for fishing and ask you to catch the Legendary Largemouth Bass. This fish is located in the southern part of the map, specifically in the waters of Lake Don Julio, near the town of San Luis. Before heading there, ensure you have the Special Lake Lure, which is essential for catching legendary fish. If you don''t have it, you can purchase it from the bait shop in Lagras, located in the Bayou Nwa region.\n\nOnce you arrive at Lake Don Julio, equip your fishing rod and attach the Special Lake Lure. Cast your line into the deeper parts of the lake, as legendary fish tend to stay in open water. Be patient and wait for the fish to bite. When it does, you''ll notice a struggle indicator on the screen. Reel in the fish by holding the right stick down to pull the rod up and then quickly rotating the left stick to reel in the line. Repeat this process until the fish is caught. Be cautious not to let the line break by keeping the tension in the green zone.\n\nAfter catching the Legendary Largemouth Bass, you must deliver it to the post office in Saint Denis. Open your satchel, select the fish, and choose the option to mail it to Jeremy Gill. Once mailed, the mission will be complete, and you''ll receive a reward. This mission also unlocks further legendary fish challenges, so keep an eye out for more letters from Jeremy Gill.\n\nFor new players, it''s important to note that fishing mechanics in RDR2 require practice. If you''re struggling to catch the fish, try practicing with smaller fish in calmer waters, such as the Dakota River. This will help you get used to the reeling mechanics and improve your timing. Additionally, always ensure your fishing rod is equipped with the correct lure for the type of fish you''re targeting. The Special Lake Lure is specifically designed for legendary fish in lakes, so using it is crucial for success.\n\nExperienced players may find this mission straightforward, but it''s still a great opportunity to explore the game''s fishing mechanics and enjoy the serene environment of Lake Don Julio. If you encounter any issues, such as the fish not biting, try moving to a different spot along the lake''s shoreline. Sometimes, changing your position can make a significant difference. Lastly, remember to save your game before attempting to catch the fish, as this will allow you to retry without losing progress if something goes wrong.\n\nIn summary, completing the ''A Fisher of Men'' challenge involves catching the Legendary Largemouth Bass at Lake Don Julio using the Special Lake Lure, then mailing it to Jeremy Gill. With patience and practice, this mission is a rewarding experience that showcases the depth of RDR2''s fishing mechanics.
