Valley Forge is a name that resonates in the minds of many Americans. As the site of the 1777-1778 encampment of the Continental army during the Revolutionary War, it has come to symbolize determination and triumph. While many people know something revolutionary happened in Valley Forge, they do not understand how or why it became a place of remembrance today. Using the rich historical collections of the National Center for the American Revolution and Valley Forge Historical Society, Valley Forge shares the early-twentieth-century history of the area through nearly two hundred images, the majority of which are published for the first time.

Valley Forge offers a variety of historical views and background into the site that became Pennsylvania's first state park. Highlights include Washington's Headquarters and the patriotic and inspiring Washington Memorial Chapel, as well as Revolutionary War artifacts that have found a home in Valley Forge. Thousands of books exist on the history of the American War for Independence, but few describe the events and people who have struggled to preserve that story of independence for people everywhere, as Valley Forge does.

Gettysburg is America's most famous battle. Fought on the first three days of July 1863, it was one of the largest and by far the bloodiest of the Civil War.

Yet the importance of this great conflagration cannot be measured in numbers alone, for Gettysburg also represented a pivotal moment in the war. The battle ended General Robert E. Lee's second invasion of Union soil, and never again did a Confederate army reach that far north. Join historian John Hoptak as he narrates the fierce action between the Confederate Army of Northern Virginia and the Union Army of the Potomac at such places as McPherson's Ridge, the Railroad Cut, the Wheatfield, the Peach Orchard, Devil's Den, Little Round Top and on Culp's and Cemetery Hills.

Since the official flag raising on July 9, 1945, the White Sands Missile Range (WSMR) has become an integral part of global defense for the United States. A mere week after formation, Project Trinity tested the first atomic bomb at an isolated site, which was 100 miles north on what was then part of the Alamogordo Bombing Range--a test site for B-17 pilots. Back at White Sands Proving Ground, as it was then named, personnel were unaware of the massive new weapon tested to their north. Instead their focus was upon the arrival of what would be 300 railroad cars of captured German V-2 rockets and associated equipment. Later that year, over 100 captured German scientists, among them Werner von Braun, would arrive at White Sands to assist in V-2 technology, launching America's race to space; tens of thousands of rockets and missiles have since been fired on the range. Thousands of family members also lived and worked at the range, and their stories can be found inside as well.

Established in 1869, Fort Sill initially hosted cavalry regiments, including buffalo soldiers, charged with pacifying native tribes in portions of Texas, Kansas, and Colorado. Replete with old West sagas, heroes, and villains, accounts from the post fascinate enthusiasts even today. Its namesake was chosen by Maj. Gen. "Little Phil" Sheridan to memorialize Brig. Gen. Joshua Sill, who gave his life in the Civil War. Similarly, the lasting impressions of great Americans are commemorated within the fort at Henry Post Army Airfield, "Flipper's Ditch," "Ambrosia Springs," "Sherman House," and of course, "Geronimo's Guardhouse." Even the city of Lawton was named after the "Prince of Quartermasters," Gen. Henry W. Lawton. Fort Sill's reputation as the premier artillery training and development center for the US Armed Forces has endured, preparing servicemen for every significant American conflict since its inception.

Luke Air Force Base, created in less than a year from desert scrub and farmland, stands some 20 miles west of Phoenix. On March 31, 1941, months before the United States entered World War II, construction began. That summer, the Army Air Corps named Luke Field after World War I hero and triple ace Frank Luke Jr. Some pilots from Luke Field's first class flew from airfields in Hawaii during the Japanese attack on Pearl Harbor. From the beginning, Luke Field trained fighter pilots, as it does today. Over the years, Luke Air Force Base was home to 14 primary fighter aircraft, graduated over 60,000 students, and accounted for millions of training flight hours. Of the pilots who trained at Luke Field, a number became aces, including the all-time US leading ace, Maj. Richard I. Bong. For decades, Luke Air Force Base has been home to more fighter aircraft than any other base in the United States, earning the moniker "Fighter Country."
