 A few weeks later, Lincoln removed General George B. McClellan from commanding the Army of the Potomac (about whom the governors had voiced their displeasure), and issued the Emancipation Proclamation.By late 1864, the majority of Pennsylvania voters had rallied around the president and supported his incumbency in the Presidential Election, giving Lincoln 296,292 votes or 51.6% of the ballots cast versus Maj. Gen. George B. McClellan's 277,443 votes (48.4%).While the war still raged, efforts were underway in Gettysburg to preserve portions of the battlefield for future generations as a tribute to those men who fought there.
