Abstract
This paper traces the founding of Fort Brooke at the mouth of the Hillsborough River in 1824 and its central role across the three decades of conflict known collectively as the Seminole Wars. It argues that Fort Brooke was the indispensable instrument of United States military policy on Florida’s Gulf frontier: the base from which the Second Seminole War was opened at the Dade battle of 1835, the principal staging depot and port that sustained the longest and costliest of America’s Indian wars, and the point of embarkation from which most of Florida’s Seminoles were deported west. The paper examines why the war proved so difficult and so expensive—the terrain, the disease, and the guerrilla character of the fighting—and considers the interpretation, advanced by several of the war’s leading historians, that the conflict was driven in significant part by the question of slavery. It closes by assessing how the fort transformed Tampa Bay from an ungoverned periphery into a permanent military town, the settlement that would become the city of Tampa.
1. Introduction
Paper III closed with the arrival of federal authority at Tampa Bay in 1824. This paper takes up what that authority built and what it did. Fort Brooke was, at its founding, a remote log cantonment on a marshy shore; within a decade it had become the operational hub of a war that consumed a generation of the antebellum Army, and within a generation it had become the nucleus of a town. Its history across the years 1824 to 1858 is inseparable from the history of the Seminole Wars, and telling it requires attention both to the fort as a military instrument and to the human costs—borne most heavily by the Seminoles—of the policy it served.
2. The Establishment of Fort Brooke, 1824
The decision to plant a post at Tampa Bay followed directly from the Treaty of Moultrie Creek of 1823, which confined most of Florida’s Seminoles to an interior reservation (see Paper III). Colonel James Gadsden, one of the treaty commissioners charged with surveying the reservation, warned Secretary of War John C. Calhoun that the Seminoles would not settle onto their assigned lands unless the United States demonstrated the power and the will to compel them, and he recommended that a military post be established at once on Tampa Bay (Covington, 1953). Calhoun accepted the recommendation, and in November 1823 orders issued from the Adjutant General’s Office directing Colonel George Mercer Brooke to proceed with four companies of the Fourth Infantry Regiment from Pensacola to Tampa Bay (Covington, 1953).
Brooke, a Virginian and a decorated veteran of the War of 1812, brought his command by sea and, in January 1824, established the post that would bear his name—first styled Cantonment Brooke—at the mouth of the Hillsborough River, on ground that later became downtown Tampa (Covington, 1953; see Note 1). Its assigned purposes were several and reflected the intertwined concerns of the early territorial period: to oversee the Seminoles confined to the nearby reservation, to serve as the point of distribution for the provisions the government had promised them, to help suppress the smuggling and unlicensed activity that had troubled the Gulf coast, and to anchor a federal presence in a newly acquired territory (Covington, 1953; Gannon, 1996). For its first decade the post was a quiet frontier station. That would change in 1835.
3. From Reservation to War: The Road to 1835
The peace established at Moultrie Creek did not hold, because federal policy did not rest there. The Indian Removal Act of 1830 committed the United States to the removal of eastern native peoples west of the Mississippi, and in 1832 the Treaty of Payne’s Landing purported to bind the Seminoles to emigrate to Indian Territory within three years. Many Seminoles regarded the treaty as fraudulent or non-binding and refused to go, and the Indian agent Wiley Thompson, charged with supervising the removal, found himself at an impasse with leaders determined to resist (Mahon, 1967; Missall & Missall, 2004). Among the most prominent of these was Osceola, whose defiance—and whose arrest and brief imprisonment in irons by Thompson—came to symbolize the Seminole refusal to be moved (Mahon, 1967).
Several of the war’s leading historians have argued that the conflict cannot be understood apart from the question of slavery. Escaped slaves and their descendants—often called Black Seminoles—had found refuge among the Seminoles, and the recovery of these people was a persistent aim of slaveholders in Georgia and Florida whose incursions into Seminole territory helped precipitate the fighting. In the reading advanced most forcefully by Frank Laumer, the Second Seminole War is properly seen as the first American war fought over slavery, driven in large part by the determination to close off Florida as a haven for the escaped and to open it for the expansion of a slaveholding society (Laumer, 1995; Missall & Missall, 2004; see Note 2). This interpretation, while debated in emphasis, has become central to modern scholarship on the war and situates the events at Tampa Bay within the larger sectional history of the antebellum republic.
4. The Dade Battle and the Opening of the War
The war began at Fort Brooke, or rather on the road that ran north from it. In late December 1835, with the removal deadline expired and tensions at the breaking point, Major Francis L. Dade was ordered to march two companies—roughly a hundred men—from Fort Brooke up the Fort King Road to reinforce the garrison at Fort King, near present-day Ocala (Laumer, 1995; Mahon, 1967). Seminole scouts watched the column leave the fort and shadowed it north. On the morning of December 28, 1835, in the pine and palmetto country north of the Withlacoochee River, some scores of Seminole warriors under leaders including Micanopy, Jumper, and Alligator ambushed the strung-out column. The command was annihilated; only a small handful of soldiers survived the day, and the interpreter Louis Pacheco was taken (Laumer, 1995).
The same day, at Fort King, Osceola and his followers killed Wiley Thompson outside the post (Mahon, 1967; Missall & Missall, 2004). The near-simultaneous blows opened the Second Seminole War. The Dade battle is conventionally taken as its starting point, and its significance for this paper is direct: the doomed column had marched out of Fort Brooke’s gate, and the fort now became the pivot of the war that followed.
5. Logistics, Terrain, and Disease: Why the War Was So Hard
Once the war began, Fort Brooke became its principal staging base on the Gulf side of the peninsula—headquarters, supply depot, hospital, and port. The scale of the buildup was considerable. The original log cantonment was rebuilt and greatly enlarged as the fighting intensified, with new wharves, storehouses, and a hospital added, and by the autumn of 1837 something on the order of sixteen hundred troops were stationed there (see Note 3). Through Fort Brooke passed the men, provisions, and matériel that sustained operations across the interior.
Yet the war defied every attempt to win it quickly, and the reasons lay in the character of the country and the nature of the fighting. The Florida interior—its cypress swamps, dense hammocks, sawgrass marshes, and, further south, the vast wetland of the Everglades—was terrain in which conventional columns of infantry and cavalry could barely operate and in which the Seminoles, fighting a mobile guerrilla war of ambush and dispersal, held every advantage (Mahon, 1967; Missall & Missall, 2004). The Army committed general after general to the effort—Clinch, Gaines, Scott, Jesup, Taylor, Armistead, and finally Worth—and cycled thousands of regulars and tens of thousands of militia and volunteers through the peninsula, all to subdue a Seminole force that never numbered more than a couple of thousand warriors and, by the war’s end, far fewer (Mahon, 1967).
Disease compounded the difficulty and did more killing than the enemy. Malaria, yellow fever, dysentery, and the other fevers of the subtropical lowlands ravaged the troops, and the sick lists routinely dwarfed the battle casualties (Mahon, 1967; Missall & Missall, 2004). The cumulative cost was staggering: the Second Seminole War consumed on the order of thirty million dollars—more than the entire annual budget of the federal government of the day—and took the lives of some fifteen hundred United States soldiers, to say nothing of the far greater proportional losses among the Seminoles (Missall & Missall, 2004). When the war was declared at an end in 1842, it was without a peace treaty and without a decisive victory; the Army simply concluded that the remaining Seminoles were too few and too deep in the Everglades to be worth the further cost of pursuit (Mahon, 1967).
6. Removal and Deportation: The Fort’s Grimmer Function
Fort Brooke’s role in the war was not confined to the logistics of combat. It was also the principal point of embarkation for the removal that was the war’s purpose. Seminoles who surrendered, were captured, or were induced to emigrate were gathered at Tampa Bay and shipped from Fort Brooke’s wharves toward New Orleans and, ultimately, Indian Territory in the West (Mahon, 1967; Missall & Missall, 2004). The fort that supplied the war also processed its human results, and in this function it became an instrument of the removal policy in the most literal sense.
The methods of that removal were often harsh, and one episode became notorious. In 1837 Osceola was seized while approaching under a flag of truce to parley—an act widely condemned at the time and since as a violation of the customs of war. He was imprisoned and died the following year in confinement in South Carolina (Missall & Missall, 2004; see Note 4). The capture stands as an emblem of the coercion that underlay the deportation Fort Brooke helped carry out.
7. The Third Seminole War, 1855–1858
The removal was thorough but not total. A few hundred Seminoles remained in the Everglades and the southwestern interior after 1842, and for more than a decade an uneasy quiet held. It broke in 1855, when the pressure of surveying, settlement, and military patrols into the remaining Seminole country provoked renewed fighting under the leader Billy Bowlegs (Holata Micco). The Third Seminole War that followed was smaller and lower in intensity than the second—a matter of raids, skirmishes, and patrols across the southern wetlands rather than large operations—but it drew once more on the Gulf coast military infrastructure of which Fort Brooke was a part (Missall & Missall, 2004). It ended in 1858 with the emigration of Billy Bowlegs and most of the remaining Seminoles, leaving only a small remnant that withdrew deep into the Everglades and was never removed—the ancestors of Florida’s present Seminole and Miccosukee communities (Missall & Missall, 2004).
8. Assessment: From Outpost to Town
The deepest mark Fort Brooke left was not on the Seminoles but on the landscape of Tampa Bay itself. The post that arrived in 1824 as an isolated garrison became, over three decades of war and supply, the nucleus of a permanent settlement. Civilians—sutlers, traders, laborers, and their families—gathered around and just north of the fort; the traffic of a wartime depot brought commerce and population that the ungoverned coast had never sustained; and out of this accretion grew the village that was incorporated as the town of Tampa in 1855 (Covington, 1958; Gannon, 1996). Growth remained slow, checked by poor transportation, recurring fever, and the long unsettlement of the Seminole conflict, but the trajectory was set. The fort had converted a strategically bypassed periphery into a fixed point of American military and civil presence.
That transformation is the lasting significance of the period. Where Papers I through III described a coast that successive powers claimed but did not hold, Fort Brooke marks the moment at which Tampa Bay was held for good. The military town it created would, within a few years, be drawn into a very different war—the subject of Paper V—when the nation that had built the fort turned upon itself.
Notes
- Sources differ slightly on the exact date of the landing and the establishment of the cantonment in January 1824, reflecting the distinction between the departure from Pensacola, the arrival in Tampa Bay, and the formal founding of the post. The month is secure; the precise day should be treated as approximate. The site had been claimed by a private party, Robert J. Hackley, who was dispossessed when the fort was established.
- The interpretation of the Second Seminole War as fundamentally a war over slavery is associated especially with Frank Laumer and is developed as well by the Missalls; it is a matter of emphasis rather than of dispute over the basic facts, since the presence of Black Seminoles and the pressure of slaveholders on Seminole territory are not seriously contested. Readers should understand the claim as an argument about the war’s underlying causes, advanced by leading historians of the conflict, rather than as the only lens through which it has been viewed.
- The figure of roughly sixteen hundred troops at Fort Brooke in the autumn of 1837 derives from the fort’s records and from archaeological and documentary reconstructions of the post at the height of the war. Garrison strength fluctuated sharply with the seasons of campaigning and with the incidence of disease, and no single number describes the fort across the war.
- The seizure of Osceola under a flag of truce in 1837 was carried out on the orders of General Thomas Jesup and was controversial immediately. It is recorded here because of its symbolic weight; a fuller treatment of the ethics and politics of the removal lies beyond the scope of a paper focused on Fort Brooke as a military installation.
- This paper treats the Seminole Wars primarily through the lens of Fort Brooke and does not attempt a full military narrative of campaigns fought far from Tampa Bay, such as the Battle of Lake Okeechobee. Readers seeking a complete operational history are directed to the works in the reference list, particularly Mahon (1967) and Missall and Missall (2004).
