The third paragraph says Lee surrendered at Appomattox Courthouse. This is a substantive error.

Courthouse as one word refers to the actual court house in a village or town. The surrender actually occurred at the McLean house (it was purposefully not done in the actual Court House so as to avoid giving it a legal imprimatur - formally recognizing the confederacy which the union never did.

The correct text should read "Lee surrendered to Grant at Appomattox Court House on April 9, 1865". It is correctly spelled later in the article (general in cheif section, 2nd para)
