These two were significant blows to the <em>Confederacy</em>, and until those victories, Lincoln winning the election had been much in doubt. One of the reasons was that the <em>Civil War</em> was taking longer than expected to come to an end - but the spirit and morale in the North were lifted due to the Union victory in the two battles. This was a crucial aspect that secured the <em>re-election</em> of President Lincoln, who, on <em>November 8</em>, defeated George McClellan (1826-1885), his <em>Democratic competitor</em>, once a Union general.
This 1864 presidential election was only held only for those states which had not separated themselves from the <em>Union</em>.
