Bryan McDonough (1814–1837)

By Matt Patsis

Early Life

Enlistment Register

Bryan McDonough was born in Sligo, Ireland, in 1814. Sometime prior to 1837, McDonough immigrated to the United States.1 Between the 1820s and 1860s, Irish immigrants made up one third of immigrants into the United States.2 Immigrants from Ireland faced discrimination and racism upon arrival, and competition for jobs was fierce.3 McDonough worked as a laborer. At twenty-one years of age, he enlisted in the US Army out of Boston, Massachusetts, as shown here.4

Military Service

The Army that Private McDonough belonged to was very different than the twenty-first century US Army. It was much smaller with about 7,200 soldiers in its ranks organized into twelve regiments composed of four artillery, seven infantry, and one dragoon or cavalry regiments. Approximately 6,600 of these soldiers were enlisted men and about 600 were officers. This small army was scattered in fifty-three separate installations around the nation. Just before the Seminole War, 500 soldiers garrisoned ten bases across northern and central Florida. Many of these men were immigrants because soldiers, wherever they served, were poorly paid; they received five dollars a month. A civilian laborer made much more. As a result, recently arrived immigrants, who needed work filled the ranks. As a result of the Second Seminole War (1835-1842), the regular Army almost doubled in size. Despite this expansion, 30,000 militia (part-time soldiers) and volunteer (newly-recruited) units reinforced the regular Army units in their campaigns in Florida against the Seminoles.5

Fought between 1835 and 1842, the Second Seminole War was part of a larger conflict between Native Americans in Florida and the United States military that lasted from 1816 to 1858. In alignment with the goals of the Indian Removal Act (1830), the United States government sought to move all the Florida Native Americans, collectively—though inaccurately—referred to as Seminoles, from the peninsula to the Indian Territory (modern-day Oklahoma). Fighting in a harsh environment, against a mobile foe using guerrilla tactics, and without clear frontlines, the army struggled to defeat their outnumbered enemy. While estimates vary, approximately 10,000 soldiers and as many as 30,000 militia fought against fewer than 2,000 Seminole warriors. Eventually, after seven years, the death of 1,400-1,500 regular US army soldiers, and the expenditure of $30,000,000-$40,000,000, the United States declared victory even while some Seminoles remained in Florida. Given these hardships, the Second Seminole War is generally considered “the longest and most costly of the Indian conflicts.”6

McDonough was part of F company in the 6th Infantry Regiment. Congress officially created the 6th Infantry Regiment in 1808.7 The 6th Infantry first participated in the War of 1812 and then moved along the western US frontier, where the soldiers built forts and engaged in skirmishes with the Native Americans, most notably in the Black Hawk War of 1832. The US Government ordered the 6th Infantry to proceed to Florida in 1836, amidst rising tension between the US and Seminoles.8 Most of the 6th Infantry, under the command of Lt. Col. Alexander R. Thompson, joined a larger force led by Col. Zachary Taylor, which moved south with orders to “destroy or capture” any Seminoles they might find.9 The 6th and the 4th Infantry regiments led the attack at the Battle of Okeechobee, but the 6th Infantry bore the brunt of the Seminole’s fire.10 They lost four officers and sixteen privates, far more than any other company in the engagement.11

Surpassed only by Dade’s Battle in terms of casualties, the Battle of Okeechobee occurred on December 25, 1837, two years after the war began. On Christmas Day, commanding officer Colonel Zachary Taylor led approximately 800 infantry regiment troops into battle against 380-480 Seminoles who were camped on the shore of Lake Okeechobee. Though Taylor claimed this battle as a great victory, the Seminoles – who had positioned themselves in a densely wooded area with a half mile of swamp in front of them – inflicted more extensive damage to the US troops than they themselves received. After three hours of battle, the Seminoles retreated in canoes across the lake, having lost less than seven percent of their men while Col. Taylor lost over seventeen percent of his forces. Further, the Seminoles successfully slowed Taylor’s march down the Kissimmee River long enough to evacuate their women and children farther into the Everglades. Public opinion regarding the battle’s outcome was initially mixed, but the nation eventually accepted Taylor’s claim of victory, propelling him into the national spotlight and initiating his road to the presidency.12


Pyramid in background of reenactment

Along with some 1,500 US casualties of the Second Seminole War, Private Bryan McDonough is memorialized at St. Augustine National Cemetery.13 On June 13, 1842, as a prelude to the formal ending of the Second Seminole War, Col. William Worth announced that the remains of the officers who fell in the war would be gathered and reinterred in the burial ground next to the St. Francis Barracks in St. Augustine. The bodies of Maj. Francis Dade and his men were interred along with other regular soldiers in three massive vaults, each covered by an ornamental pyramid constructed of native coquina stone. Two years later, a granite obelisk was erected next to the pyramids. The US Government re-designated the St. Francis Barracks burial ground as St. Augustine National Cemetery in 1881. The so-called “Dade Pyramids” and memorial obelisk are believed to be among the oldest public monuments (excluding headstones) in the national cemetery system.14
