You had accompanied Hosea and Dutch as well as some other men from camp on a mission to rob a bank in Saint Denis. The mission backfired and Pinkertons showed up.

You were hiding behind a wall trying to stay in cover as the Pinkertons brought out Hosea. Having captured him.

You had always seen him as your father ever since he found you and brought you back. You could only watch as the agents brutally shot Hosea. Watching as he collapsed dead on the cobblestone street.
