A Different Viewpoint of Lew Powell's Character

[RJNorton]

I have several questions for you folks who know much more than myself. The possible role of Mosby being somehow connected to the assassination is a very weak area (knowledge-wise for me).

Here are my questions:

1. Was it Mosby who sent Harney on his "explosives" mission?

2. Did Booth know of the failure of Harney's mission?

3. If he did, could this be considered another motivating factor in the timing of the assassination because the failure took place only a few days before Booth acted?
