The National Cemetery Administration (NCA) serves as the steward for government and military lots at select private cemeteries nationwide. The Congressional Cemetery in Washington, D.C., is home to several of these lots containing more than 800 burial sites in locations scattered across the 35-acre grounds. Interred within are members of Congress,  prisoners of war, a U.S. vice president, Native American dignitaries,  and  government employees. Their graves are marked by headstones that come in a variety of shapes and sizes. One of the largest markers is the monument honoring the women who died in an explosion at the Washington Arsenal during the Civil War.

On June 17, 1864, female workers—many of whom were young, Irish immigrants—were busy assembling ammunition cartridges at the Washington Arsenal, a U.S. Army installation (now Fort McNair) at the confluence of the Potomac and Anacostia Rivers. The weather that day was sweltering, with temperatures approaching 100 degrees. Just before noon, red and white star pellets used in fireworks that were drying on metal trays outside the women’s workspace ignited in the heat. The pyrotechnics flew into the air and one pellet entered a window left open for ventilation. It skidded across the worktable, igniting the cartridges being assembled, and landed in a barrel of gunpowder. The ensuing explosion blew the roof off the building and fire engulfed the women wearing highly flammable cotton shirts and hoopskirts. The building was consumed in minutes and twenty-one women died.

The local community was devastated by the explosion. Secretary of War Edwin Stanton ordered the War Department to pay for all funeral expenses. A large crowd of people attended the funeral at the arsenal and thousands more turned out for the burial procession to Congressional Cemetery. President Abraham Lincoln joined the events as the “mourner in chief.” A few days later, arsenal  employees took up a collection to donate a day’s wages to establish a monument to honor the victims of the tragedy.

Irish-American sculptor Lot Flannery was commissioned to design and carve a memorial to place at the gravesite of the fifteen women buried in one of the cemetery’s government lots. The other six were interred in family plots at the cemetery or elsewhere. Flannery completed the 25-foot-tall marble shaft on a granite base before the anniversary of the explosion at a cost of just over $3,000. He topped the monument with a female figure symbolizing grief that is visible well beyond the cemetery’s walls.

The front face of the monument shaft features a carving of the arsenal explosion; the east and west faces are inscribed with the names of all twenty-one women who died in the accident. In 2008, NCA treated the monument to slow the erosion of the marble and inscriptions. In 2014, a granite marker engraved with the victims’ names was placed in front of the monument as those on the shaft had faded. The following year, on the sesquicentennial of the monument’s completion, it was rededicated.

    History of VA in 100 Objects

    In the 19th century, the federal government left the manufacture and distribution of prosthetic limbs for disabled Veterans to private enterprise. The experience of fighting two world wars in the first half of the 20th century led to a reversal in this policy.

    In the interwar era, first the Veterans Bureau and then the Veterans Administration assumed responsibility for providing replacement limbs and medical care to Veterans.

    In recent decades, another federal agency, the Defense Advanced Research Project Agency (DARPA), has joined VA as a supporter of cutting-edge research into artificial limb technology. DARPA’s efforts were spurred by the spike in traumatic injuries resulting from the emergence of improvised explosive devices as the insurgent’s weapon of choice in Iraq in 2003-04.

    Out of that effort came the LUKE/DEKA prosthetic limb, named after the main character from "Star Wars."

    American prisoners of war from World War II, Korea, and Vietnam faced starvation, torture, forced labor, and other abuses at the hands of their captors. For those that returned home, their experiences in captivity often had long-lasting impacts on their physical and mental health. Over the decades, the U.S. government sought to address their specific needs through legislation conferring special benefits on former prisoners of war.

    In 1978, five years after the United States withdrew the last of its combat troops from South Vietnam, Congress mandated VA carry out a thorough study of the disability and medical needs of former prisoners of war. In consultation with the Secretary of Defense, VA completed the study in 14 months and published its findings in early 1980. Like previous investigations in the 1950s, the study confirmed that former prisoners of war had higher rates of service-connected disabilities.

    History of VA in 100 Objects

    In the waning days of World War I, French sailors from three visiting allied warships marched through New York in a Liberty Loan Parade. The timing was unfortunate as the second wave of the influenza pandemic was spreading in the U.S. By January, 25 of French sailors died from the virus.

    These men were later buried at the Cypress Hills National Cemetery and later a 12-foot granite cross monument, the French Cross, was dedicated in 1920 on Armistice Day. This event later influenced changes to burial laws that opened up availability of allied service members and U.S. citizens who served in foreign armies in the war against Germany and Austrian empires.
