There was no larger news story in the latter nineteenth century after the assassination of Abraham Lincoln. The story of the Johnstown Flood has everything to interest the modern mind: a wealthy resort, an intense storm, an unfortunate failure of a dam, the destruction of a working class city, and an inspiring relief effort. The rain continued as men worked tirelessly to prevent the old South Fork Dam from breaking. Elias Unger, the president of the South Fork Fishing and Hunting Club, was hoping that the people in Johnstown were heeding the telegraph warnings sent earlier, which said that the dam might go. When it finally happened, at 3:10 P.M., May 31, 1889, an era of the Conemaugh Valley's history ended, and another era started. Over 2,209 people died on that tragic Friday, and thousands more were injured in one of the worst disasters in our Nation's history. Johnstown Flood National Memorial is located in southwestern Pennsylvania, about 10 miles northeast of Johnstown. The park contains nearly 165 acres and preserves the remains of the South Fork Dam and portions of the former Lake Conemaugh bed.

To properly bury the Union soldiers who died at Gettysburg, a "Soldiers Cemetery" was established on the battleground near the center of the Union line. Pennsylvania Governor Andrew Curtin supported the proposal with state funds to purchase the cemetery grounds and pay for the reinterment of Union dead from inadequate grave sites that covered the battlefield. It was here during the dedication ceremony on November 19, 1863, that President Abraham Lincoln spoke of "these honored dead..." and renewed the Union cause to reunite the war-torn nation with his most famous speech, the "Gettysburg Address". The cemetery was landscaped by William Saunders, founder of the National Grange. The Cemetery was completed by 1872, and turned over to the care of the Federal government. In 1933 responsibility of the cemetery was transferred from the War Department to the National Park Service. Today, the Gettysburg National Cemetery is the final resting place for American veterans from all of this country's major wars and conflicts. It is closed to new burials. The cemetery is also the site of numerous monuments and memorials including the "Friend to Friend" Memorial in the National Cemetery Annex.

Fought in the first three days of July 1863, the Battle of Gettysburg resulted in a hallmark victory for the Union "Army of the Potomac" and successfully ended the second invasion of the North by General Robert E. Lee's "Army of Northern Virginia". Historians have referred to the battle as a major turning point in the war, the "High Water Mark of the Confederacy". It was also the bloodiest single battle of the war, resulting in over 51,000 soldiers killed, wounded, captured or missing. The Soldiers' National Cemetery at Gettysburg was dedicated on November 19, 1863, when President Abraham Lincoln delivered his immortal Gettysburg Address. The cemetery contains more than 7,000 interments including over 3,500 from the Civil War. Post-battle efforts preserved small portions of the battlefield as a memorial to the Union victory. On February 11, 1895, congressional legislation was signed to establish Gettysburg National Military Park as a memorial dedicated to the armies that fought this great battle. Gettysburg National Military Park incorporates nearly 6,000 acres, with 26 miles of park roads and over 1,400 monuments, markers, and memorials.
