What caused Confederate General Robert E Lee to plan an assault on Harpers Ferry?

Because General Robert E. Lee found he could not live off the land in Maryland, he needed to open a supply line to the Valley. In order to accomplish this he had to reduce Harpers Ferry and also Martinsburg.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
