At the start of the game the entire gang is fleeing due to the events that happened in Blackwater. From what some of the other gang members tell you, there was a heist planned on a boat, and it went horribly wrong somehow. And now law enforcement and the Pinkertons are chasing after the gang.
There are some allusions to what happened in the first chapter conversations, but there doesn't seem to be a clear explanation of the details. Are the details of the events intentionally left unclear for the entire game, or are there some actual accounts of what happened on the boat in Blackwater?
Another suspicion based on the events much later in the game (be warned, this contains a serious spoiler for the last chapters):
We get to know that Micah was an informant later in the game. My original understanding was that he only started to pass information at a later point, but are there any hints or evidence that he might already had a hand in ensuring that the Blackwater events lead to disaster?
