Gettysburg, Pennsylvania in the context of "Gettysburg National Cemetery"

Mary Geneva "Mamie" Eisenhower (née Doud; November 14, 1896 – November 1, 1979) was the first lady of the United States from 1953 to 1961 as the wife of President Dwight D. Eisenhower. Born in Boone, Iowa, she was raised in a wealthy household in Colorado. She married Eisenhower, then a lieutenant in the United States Army, in 1916. She kept house and served as hostess for military officers as they moved between various postings in the United States, Panama, the Philippines, and France. Their relationship was complicated by his regular absences on duty and by the death of their firstborn son at the age of three. She became a prominent figure during World War II as General Eisenhower's wife.

As first lady, Eisenhower was given near total control over the expenses and scheduling of the White House. She closely managed the staff, and her frugality was apparent in White House budgeting throughout her tenure. She entertained many foreign heads of state in her role as hostess. She showed little interest in politics and was rarely involved in political discussion, though she did support soldiers' welfare and civil rights causes. She had poor balance due to Ménière's disease, giving rise to rumors of alcoholism. She was a popular first lady, and recognized as a fashion icon, known for her iconic bangs and frequent use of the color pink. The Eisenhowers were married for 52 years, until Dwight's death in 1969. She spent most of her retirement and widowhood at the family farm in Gettysburg, Pennsylvania, before returning to Washington in her final years, where she died in 1979. Eisenhower was the last First Lady born in the 19th century.

The Battle of Gettysburg (locally /ˈɡɛtɪsbɜːrɡ/ ) was a three-day battle in the American Civil War, which was fought between the Union and Confederate armies between July 1 and July 3, 1863, in and around Gettysburg, Pennsylvania. The battle, won by the Union, is widely considered the Civil War's turning point, leading to an ultimate victory of the Union and the preservation of the nation. The Battle of Gettysburg was the bloodiest battle of both the Civil War and of any battle in American military history, claiming over 50,000 combined casualties. Union Major General George Meade's Army of the Potomac defeated attacks by Confederate General Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North and forcing his retreat.

After his success in the Battle of Chancellorsville in Spotsylvania County, Virginia in May 1863, Lee led his Confederate forces through Shenandoah Valley to begin the Gettysburg campaign, his second attempt to invade the North. With Lee's army in high spirits, he intended to shift the focus of the summer campaign from war-ravaged Northern Virginia in the hopes of penetrating as far as Harrisburg or Philadelphia, which he hoped would convince northern politicians to end the war. President Abraham Lincoln initially prodded Major General Joseph Hooker into pursuing Lee, then relieved him of command just three days before the Battle of Gettysburg commenced, replacing him with Meade.

The Gettysburg Address is a speech delivered by Abraham Lincoln, the 16th U.S. president, following the Battle of Gettysburg during the American Civil War. The speech has come to be viewed as one of the most famous, enduring, and historically significant speeches in American history.

Lincoln delivered the speech on the afternoon of November 19, 1863, during a formal dedication of Soldiers' National Cemetery, now known as Gettysburg National Cemetery, on the grounds where the Battle of Gettysburg was fought four and a half months earlier, between July 1 and July 3, 1863, in Gettysburg, Pennsylvania. In the battle, Union army soldiers successfully repelled and defeated Confederate forces in what proved to be the Civil War's deadliest and most decisive battle, resulting in more than 50,000 Confederate and Union army casualties in a Union victory that altered the war's course in the Union's favor.

Adams County is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the population was 103,852. Its county seat is Gettysburg. The county was created on January 22, 1800, from part of York County, and was named for John Adams, the second President of the United States.

Between July 1 and July 3, 1863, the Battle of Gettysburg, the bloodiest and most significant battle of the American Civil War, was fought near Gettysburg. As a result, Adams County is a center for Civil War-related tourism. Adams County comprises the Gettysburg metropolitan statistical area, which is also included in the Harrisburg–York–Lebanon combined statistical area. The county is part of the South Central region of the commonwealth.

The military history of the United States spans over four centuries, dating back to 1607 and pre-dating by nearly two centuries the founding of the nation following the American Revolutionary War. During this moment, the United States evolved from a colonial territory to newly formed nation following its independence from the Kingdom of Great Britain (1775–1783) to ultimately becoming a world superpower in the aftermath of World War II and through the present. As of 2024, the United States Armed Forces consists of the Army, Marine Corps, Navy, Air Force and Space Force, all under the command of the Department of Defense, and the Coast Guard, which is controlled by the Department of Homeland Security.

In 1775, the Continental Congress, convening in present-day Independence Hall in Philadelphia, established the Continental Army, the Continental Navy, and the Continental Marines, formally joining and escalating its war for independence in the Revolutionary War. This newly formed military, fighting alongside the Kingdom of France, triumphed over the British in the war, leading to its independence following the signing of the Treaty of Paris in 1783. In 1789, the new Constitution made the U.S. president the commander-in-chief, and gave Congress the authority to declare war. Major conflicts involving the U.S. military include the American Revolutionary War, American Indian Wars, War of 1812, Mexican–American War, American Civil War, Spanish–American War, World War I, World War II, Korean War, Vietnam War, Gulf War, War in Afghanistan, Iraq War, and the war against the Islamic State.

United States Volunteers (also called U.S. Volunteers, U.S. Volunteer Army, among other variations) were military volunteers called upon during wartime to help the United States Army. They were separate from the Regular Army and the militia.

Until the Militia Act of 1903, the land forces of the United States were divided into three organizations:

U.S. Route 15 (US 15) is United States Numbered Highway that runs from Walterboro, South Carolina, north to Painted Post, New York. In Pennsylvania, the highway runs for 194.89 miles (313.65 km), from the Maryland state line just south of Gettysburg, north to the New York state line near Lawrenceville.

The Gettysburg campaign was a military invasion of Pennsylvania by the main Confederate army under General Robert E. Lee in summer 1863. It was the first time during the war the Confederate Army attempted a full-scale invasion of a free state. The Union won a decisive victory at Gettysburg, July 1–3, with heavy casualties on both sides. Lee managed to escape back to Virginia with most of his army. It was a turning point in the American Civil War, with Lee increasingly pushed back toward Richmond until his surrender in April 1865. The Union Army of the Potomac was commanded by Maj. Gen. Joseph Hooker and then (from June 28) by Maj. Gen. George Meade.

After his victory in the Battle of Chancellorsville, Lee's Army of Northern Virginia moved north for a massive raid designed to obtain desperately needed supplies, to undermine civilian morale in the North, and to encourage anti-war elements. Lee's army slipped away from Federal contact at Fredericksburg, Virginia, on June 3, 1863. The largest predominantly cavalry battle of the war was fought at Brandy Station on June 9. The Confederates crossed the Blue Ridge Mountains and moved north through the Shenandoah Valley, capturing the Union garrison at Winchester, in the Second Battle of Winchester, June 13–15. Crossing the Potomac River, Lee's Second Corps advanced through Maryland and Pennsylvania, reaching the Susquehanna River and threatening the state capital of Harrisburg. However, the Army of the Potomac was in pursuit and had reached Frederick, Maryland, before Lee realized his opponent had crossed the Potomac. Lee moved swiftly to concentrate his army around the crossroads town of Gettysburg.
