I have just finished up several books by the same author.  The author was Stephen W. Sears.  Mr. Sears is an excellent writer.  The books were Gettysburg, To The Gates of Richmond (the seven days battles,) Chancellorsville, and Landscape Turned Red.  The latter is about Antietam.  If you haven’t given Stephen W. Sears a read, he is well worth the time and the price of the books.
