In the book, Missouri's Confederate: Claiborne Fox Jackson and the Creation of Southern Identity in the Border West, by Christopher Phillips, I am having trouble with the author's arguments. I have finished my paper, but I was told by a proof-reader that I should "Assess the author's argument that Missourian's viewed themselves as southerners." Also, I was told to add something about what evidence does the author marshal to support his position. I am having trouble with this. Please help!
