During the passage of the game Red Dead Redemption 2 in the North of the game world, the main character will meet a stranger. This will happen between Chapter 5 and 6. This meeting will start a series of quests with a veteran hunter. One of the tasks is to find old Hamish named Buell.
You can find the owner of the horse on the road from the Three Sisters. The animal itself will also be located nearby, just go to the lake and go up the road. The horse will be near the shore. Before saddling the animal, you will need to calm it down. After that, we need to go back to Hamish. This will be the final of the first of four side missions, to continue the series of quests on the next day, you will need to return to the old man's house.
You can keep the horse you find. To do this, you just need to continue to pass side quests. The result will be an increase in the level of honor. But first you need to make sure that there is enough space in the stable for your new pet.
