This is the article in question: http://www.tenc.net/a/18611025.htm. For my history coursework I need 2 interpretations and 3 primary sources. I'm unsure on which this counts on as it means I might not be able to use it and I have to find something else. Thanks for your time.
It's an interesting article - thank you! For the benefit of future searches, and in case the link dies, it's Karl Marx, "The North American Civil War", Die Presse (Vienna), 25 October 1861.
What is the exact question or problem that the teacher has posed to you? For example, if the question relates to the development of Marx's thinking on <X>, surely it's a primary source.
