First, that is like saying, "Tell me what happened in Germany in the fall of 1991". Do you know detailed specifics? Surely not. I am not a historian.
Also, your understanding of temporal navigation is slightly misplaced. In our world line, we are limited or constrained on our ability to travel back in time. The further back we go, the more inaccurate we are in terms of navigation. This means, that if we were to go back much further, I would end up on a world line that is vastly different.
In our parameters, we can reasonably travel back up to 40 years with up to 3% divergence
