Henry, As to the point of Delaware and slavery:
Delaware's General Assembly refused to ratify the 13th Amendment, calling it an illegal extension of federal powers over the states. Only in December 1865, when the 13th Amendment went into effect on a national scale, did slavery unofficially cease in Delaware. By then there were only a few hundred left. Many male slaves had run off in 1863 and 1864 and gone to the cities to enlist in black regiments. The 13th Amendment was not ratified in Delaware until (February 12, 1901, after having rejected it on February 8, 1865)
Delaware provided upwards of 3000 troops to the Southern Cause from Delaware (Union estimate)
