Hi David –
I can’t help you decide which field to pursue, but you gotta admit ancient history, the American Revolution, and the Civil War are pretty different things. Speaking from experience, the folks in ancient history have a rougher time when it comes to writing the thesis, basically because of the small number of primary sources. But the closer you get to the present, those sources more or less explode. In a perfect world primary sources drive the thesis.
