Union army in the context of "Gettysburg, Pennsylvania"

The U.S. Pledge of Allegiance is a patriotic recited verse that promises allegiance to the flag of the United States and the republic of the United States. The first version was written in 1885 by Captain George Thatcher Balch, a Union army officer in the Civil War who later wrote a book on how to teach patriotism to children in public schools. In 1892, Francis Bellamy revised Balch's verse as part of a magazine promotion surrounding the World's Columbian Exposition, which celebrated the 400th anniversary of Christopher Columbus' arrival in the Americas.

Bellamy, the circulation manager for The Youth's Companion magazine, helped persuade then-president Benjamin Harrison to institute Columbus Day as a national holiday and lobbied Congress for a national school celebration of the day. The magazine sent leaflets containing part of Bellamy's Pledge of Allegiance to schools across the country and on October 21, 1892, over 10,000 children recited the verse together.

George Gordon Meade (December 31, 1815 – November 6, 1872) was an American military officer who served in the United States Army and the Union army as a major general in command of the Army of the Potomac during the American Civil War from 1863 to 1865. He fought in many of the key battles of the eastern theater and defeated the Confederate Army of Northern Virginia led by General Robert E. Lee at the Battle of Gettysburg.

He was born in Cádiz, Spain, to a wealthy Philadelphia merchant family and graduated from the United States Military Academy in 1835. He fought in the Second Seminole War and the Mexican–American War. He served in the United States Army Corps of Topographical Engineers and directed construction of lighthouses in Florida and New Jersey from 1851 to 1856 and the United States Lake Survey from 1857 to 1861.

The Army of the Potomac was the primary field army of the Union army in the Eastern Theater of the American Civil War. It was created in July 1861 shortly after the First Battle of Bull Run and was disbanded in June 1865 following the surrender of the Confederate Army of Northern Virginia in April.

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 Union navy is used to describe the United States Navy (USN) during the American Civil War, when it fought the Confederate States Navy (CSN). The term is sometimes used to describe vessels of war used on the rivers of the interior under the control of the Union army.

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.

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.

Philip Henry Sheridan (March 6, 1831 – August 5, 1888) was a career United States Army officer and a Union general in the American Civil War. His career was noted for his rapid rise to major general and his close association with General-in-chief Ulysses S. Grant, who transferred Sheridan from command of an infantry division in the Western Theater to lead the Cavalry Corps of the Army of the Potomac in the East. In 1864, he defeated Confederate forces under General Jubal Early in the Shenandoah Valley and his destruction of the economic infrastructure of the Valley, called "The Burning" by residents, was one of the first uses of scorched-earth tactics in the war. In 1865, his cavalry pursued Gen. Robert E. Lee and was instrumental in forcing his surrender at Appomattox Courthouse.

In his later years, Sheridan fought in the Indian Wars against Native American tribes of the Great Plains. He was instrumental in the development and protection of Yellowstone National Park, both as a soldier and a private citizen. In 1883, Sheridan was appointed general-in-chief of the U.S. Army, and in 1888 he was promoted to the rank of General of the Army during the term of President Grover Cleveland.

Peter Arrell Browne Widener (November 13, 1834 – November 6, 1915) was an American businessman, art collector, and patriarch of the wealthy Widener family. He began his career as a butcher, ran a successful chain of meat stores, and won a lucrative contract to supply mutton to Union army troops during the American Civil War. He partnered with William Lukens Elkins and William H. Kemble to found the Philadelphia Traction Company and established electric trolley systems in several major cities in the United States.

He was one of the founding organizers of American Tobacco Company, International Mercantile Marine Company, and U.S. Steel, and held significant investments in railroads, oil, and natural gas. He assembled a vast art collection valued between $15 and $50 million that he displayed at his Lynnewood Hall estate. Widener is on the American Heritage list of the forty richest Americans in history.
