Thank you for this post. There are hundreds more like it by Confederate veterans and other Southerners who lived at that time. The most important lines are --

The people of the South believed that they would be deprived of their right of property without due process of law, and without compensation; and, entertaining that belief, there was nothing left for them to do but to resort to arms to defend their right of property, or to cowardly abandon it without a struggle.

When people allude to the Constitution being compromised, they are referring to property in slaves. However, having successfully eliminated that form of property on moral grounds, a reasonable person might consider, what other rights might the Federal government abolish?
