On the south side of St. Augustine National Cemetery in Florida, there are three squat pyramids and a single taller obelisk. The Dade Pyramids and Monument, as they are known, mark the resting place of the U.S. soldiers who died in the opening engagement of the Second Seminole War (1835-42). The memorial honors lives lost while also serving as a grim reminder of the brutal conflict that erupted when the Federal government tried to evict the Seminole people from their tribal lands in central Florida.

In 1832, the United States negotiated a treaty signed by only some Seminole chiefs that gave the Seminoles three years to relocate to territory set aside for Native use west of the Mississippi River. Seminole leaders afterwards repudiated the agreement. In 1835, as the treaty deadline approached, both sides braced for battle. A Native leader named Osceola assembled approximately 1,000 warriors to resist any effort by U.S. troops to remove the Seminole.

In late December 1835, Maj. Francis Dade received orders to reinforce Fort King (near present-day Ocala), with the 107 regulars under his command. As the column neared the fort on December 28, Dade, who had been anticipating an ambush for days, grew lax and recalled his scouts. His decision proved fatal.

In a pine barren near present-day Bushnell, Florida, Seminole warriors attacked Dade’s troops from several sides. Dade and many of his fellow officers died in the first volley. Deprived of leadership, the remaining soldiers were unable to mount an effective defense. Only two or three men survived the ambush. It took the U.S. Army over two months to recover the bodies of the deceased and bury them on the battlefield.

The U.S. efforts to subjugate the Seminole turned into a long and costly campaign. The fighting finally petered out in 1842, without a formal agreement to end hostilities. The war inflicted grievous harm on the Seminole people. About 3,000 died during the conflict, including women and children. Most of the survivors moved west, but several hundred refused to accept defeat and took refuge in the Everglades region. The U.S. dead numbered over 1,400. 

In June 1842, Col. William J. Worth ordered the remains of every U.S. soldier who perished during the war transported to St. Augustine for permanent interment in the burial plot at the Army’s St. Francis Barracks. Worth also asked all officers and enlisted personnel in Florida to contribute a day’s pay from their salary to erect a monument to Dade and his men.

He intended to use the donations to construct three “suitable vaults” covered by “unostentatious monuments” for the deceased. The vaults were finished and the remains buried in a large ceremony held on August 15. Three five-foot tall pyramids stood above the vaults. The pyramids were made of coquina, a porous limestone rock composed of seashell fragments native to the area. A smooth layer of stucco painted white coated their exterior.

The estimated 165 persons interred in the vaults included not just the members of Dade’s company but other casualties from the war as well. Worth reported that the vaults and pyramids cost just $41.81, leaving him with $400 in unspent donations. He decided to use the leftover money to add an 18-foot obelisk made of coquina and marble at the burial site. Each side of the obelisk bears a different inscription. The north face reads, “Sacred to the memory of the Officers and Soldiers killed in battle and died in service during the Florida War.”

The memorial attracted its share of visitors, but interest in the pyramids and obelisk  waned over time. In the early 20th century, other sites related to the Dade ambush and the Seminole War came to overshadow this one. In 1921, the Florida state legislature appropriated funds to create a memorial park at the spot where the battle occurred. Initially known as the Dade Massacre Park, the state park has become a popular destination for locales and day-trippers interested in exploring its history or enjoying its many outdoor attractions.

In 1973, VA assumed responsibility for most of the Army’s national cemeteries, including St. Augustine. By then, Florida’s subtropical climate had worn away the stucco exterior of the three Dade Pyramids. VA chose to maintain the pyramids in the condition they were received, meaning without the whitewashed stucco. While the Dade Battlefield Historic State Park draws a crowd to its annual reenactment of the battle, VA performs the somber task of ensuring that the first and oldest memorialization of the U.S. soldiers who died in the Second Seminole War is properly preserved.

    For a time during and after World War II, active duty military personnel were assigned to the Veterans Administration.

    That assignment was represented by a blue circle with a golden phoenix rising from the ashes. This was the shoulder patch worn by the more than 1,000 physicians, dentists, and other medical professionals serving in the U.S. Army at VA medical centers.

    This was the same patch worn by Gen. Omar Bradley during his time as VA administrator after the war concluded.

    “The following pages are devoted to the memory of those heroes who have given up their lives upon the altar of their country, in defense of the American Union.”

    So opened the preface to the first volume of the Roll of Honor, a compendium of over 300,000 Federal soldiers who died during the Civil War and were interred in national and other cemeteries. The genesis of this 27-volume collection published between 1865 and 1871 can be traced to Quartermaster General Montgomery C. Meigs and the department he oversaw for a remarkable 21 years from 1861 to 1882.

    Object 85: Congressman Claypool’s “$1 Per Day Pension” Ribbon

    Founded in 1866 as fraternal organization for Union Veterans, the Grand Army of the Republic (GAR) embraced a new mission in the 1880s: political activism. The GAR formed a pension committee in 1881 for the express purpose of lobbying Congress for more generous pension benefits.

    An artifact from the political wrangling over pensions is now part of the permanent collection of the National VA History Center in Dayton, Ohio. The item is a small pension ribbon displaying the message: “I endorse the $1 per day pension as recommended by the Departments of Ohio and Indiana G.A.R.” The button attached to the ribbon features two American flags and the phrase “saved by the boys of ’61-65.” The back of the ribbon bears the signature of Horatio C. Claypool, a Democratic judge who ran for the seat in Ohio’s eleventh Congressional district in the 1910 mid-term elections.
