Military & Wartime

Peters Township, PA · est. 1915

Fort Loudon was built by Colonel John Armstrong in the winter of 1756 to guard the Pennsylvania frontier during the French and Indian War, replacing the earlier post at McDowell's Mill. It became a key staging point for the campaigns of General John Forbes in 1758 and Colonel Henry Bouquet in 1763–64, and the base from which pack-horse trains set out for the west. In 1765 it was the scene of the defiant exploits of Captain James Smith and his 'Black Boys,' frontiersmen who resisted the arms trade with hostile tribes.

Dublin Township, PA · est. 1967

Begun in 1755 by frontier trader and Indian agent George Croghan, Fort Lyttelton was one of a string of provincial strongholds thrown up across Pennsylvania during the French and Indian War. Named by Governor Morris for Sir George Lyttelton, Britain's Chancellor of the Exchequer, it sheltered provincial soldiers, regulars, and local volunteers through the frontier violence of the 1750s and the 1763 uprising. By 1764 the fort had already fallen into ruins, its wartime purpose spent.

Franklin, PA · est. 1969

During the French and Indian War, the French built Fort Machault here in 1756 to help secure their chain of posts guarding the route to the contested Ohio Country. Its usefulness ended in 1759, when the fall of Fort Niagara forced the French to abandon and burn their positions along the upper Allegheny. The site of the fort lies a block to the south of the marker.

Austin, TX

In the winter of 1863-64, Confederate engineers threw up this L-shaped earthen fort near Congress Avenue, one of three planned to shield Austin from a feared Union thrust up from the coast. Named for Gen. John Bankhead Magruder, commander of Texas's Confederate forces, it was built by enslaved people supplied by citizens amid wartime labor shortages. When Union forces struck instead from Louisiana's Red River in early 1864, the never-tested fort was abandoned.

East Hanover Township, PA · est. 1970

During the French and Indian War, settler James Brown's fortified log house served as a frontier strongpoint, garrisoned as Fort Manada from January 1756 to May 1757 as an outpost of nearby Fort Swatara. A small complement of about twenty-one officers and men manned it against raids along Pennsylvania's exposed backcountry. No description of the structure itself survives, leaving only its story on the land.

Sabine Pass, TX

During the Civil War, Confederate General John B. Magruder ordered this fort built on September 4, 1863—just four days before Dick Dowling's small company famously repelled a Union fleet at nearby Sabine Pass. When a September storm drove the Union coaling ship Mannahassett ashore, Confederates seized its cargo and even borrowed its name for the new fort. Designed by former Austrian officer Valery Sulakowski and engineered by Swiss-born Getulius Kellersberger, the five-redoubt fort guarded the Texas coast with ten cannons.

Montgomery Township, PA · est. 1946

Built about 1755 on William Marshall's land near the Old Warm Spring Trail, this refuge was one link in the frontier's early-warning network. It served as a station on the daily military patrols that guarded the Conococheague Settlement against raids during the French and Indian War. Riders moving between such posts carried word of danger, giving scattered farm families precious time to reach safety.

Biddeford, ME

This Daughters of the American Revolution monument marks the site of Fort Mary, a garrison that stood at Winter Harbor in Biddeford beginning around 1700. Small wooden forts like this guarded Maine's exposed frontier through the long series of colonial wars among English settlers, the French, and their Native allies. For generations the fort offered refuge to a coastal community repeatedly caught in the crossfire of empire.

Masontown, PA · est. 1946

On the trans-Appalachian frontier of the 1770s, isolated families built their own defenses long before any army arrived. John Mason raised this blockhouse between 1774 and 1778, a stout log structure meant to shelter neighbors when danger threatened during the Revolutionary years. When the fighting passed, the timbers found a second life relocated to Main Street as an ordinary dwelling — the frontier fort quietly becoming a family home.

Mason, TX

When Texas seceded, Fort Mason and the newly established Camp Llano became links in a Confederate line of frontier posts, spaced a day's ride apart from the Red River to the Rio Grande. Occupied first by the First Regiment Texas Mounted Rifles and then the Frontier Regiment, these troops guarded scattered settlers against raids while the war raged elsewhere. Locals took shelter at Fort Mason, and even a lone mail carrier crept between the posts by night, dodging raiders to keep the mail moving.

Cross Plains, TX

Between 1851 and 1861, the U.S. 2nd Cavalry and its supply trains moved along this route linking Fort Mason to Camp Cooper during the army's antebellum campaigns against the Plains Indians. Among the officers who traveled the road were men soon to become giants of the Civil War, including Robert E. Lee and George H. Thomas, the future 'Rock of Chickamauga.'

Mason, TX

The U.S. Army established Fort Mason on July 6, 1851, to shield the Texas frontier, naming it for Lt. George T. Mason, who had been killed near Brownsville in the war with Mexico. Between 1856 and 1861 it hosted officers of the famed 2nd U.S. Cavalry — Albert Sidney Johnston, George H. Thomas, Earl Van Dorn, and Robert E. Lee — many of whom would win fame or infamy in the coming Civil War. Federal troops abandoned the post in March 1861 and returned only after the war, garrisoning it until 1869.

Bloomsburg, PA · est. 1948

After frontier raids destroyed nearby Fort Jenkins in 1780, the noted borderland fighter Moses Van Campen stockaded the McClure house early in 1781 to shelter settlers along the north bank of the Susquehanna. The improvised fort stood in what is now Bloomsburg, part of a chain of refuges thrown up as the Revolution's frontier war ground on. Such places were less military garrisons than desperate havens for families caught between armies and raiding parties.

Hamilton Township, PA · est. 1947

In the tense years of the French and Indian War, Pennsylvania's Cumberland Valley settlers threw up log stockades like Fort McCord to shelter their families when frontier violence flared. Named for the settler John McCord, this refuge was overwhelmed and burned on April 1, 1756, in a raid that left 27 people dead or dragged into captivity. Such attacks were part of the wider war between Britain and France, in which allied Native nations struck deep into the exposed backcountry.

Hamilton Township, PA · est. 1914

On April 1, 1756, Fort McCord — one of the small stockaded refuges thrown up along Pennsylvania's Cumberland Valley frontier during the French and Indian War — was overrun, and twenty-seven settlers were killed or carried off. A militia party that gave chase was itself ambushed days later at Sideling Hill, where many of the pursuers fell. The marker names the women, children, and provincial soldiers lost, preserving a roll of the dead from one of the war's bloodiest weeks on the backcountry.

Humboldt County, NV

Established in 1865 as Quinn River Camp #33, this post was renamed Fort McDermitt for a district commander killed while fighting Native peoples. A cluster of adobe, stone, and frame buildings around a central square, it guarded the road linking Virginia City, the Quinn River Valley, and Oregon. Its troops took part in the Modoc War and in campaigns against the Bannock and Shoshone, and after twenty-four years—the longest active service of any Nevada army fort—it became an American Indian reservation school in 1889.

Peters Township, PA · est. 1947

When war swept the frontier after 1755, John McDowell's gristmill was ringed with a stockade and pressed into service as a provincial strongpoint until the more substantial Fort Loudon rose the next year. The site also anchored one end of Colonel James Burd's road, cut in 1755 to carry troops and supplies westward toward the Ohio country. A working mill thus became both a fort and a gateway into the contested interior.

Peters Township, PA · est. 1916

Fort McDowell grew up around a frontier gristmill before 1754, then became a supply base and munitions store as the French and Indian War closed in, holding that role until Fort Loudon was raised in 1756. From this point in 1755 Col. James Burd pushed a military road westward to link with Braddock's ill-fated route at Turkey Foot. Standing at the edge of settled country, the little fort saw its share of the war's frontier alarms.

Baltimore, MD

This iron bomb was hurled from a British warship during the two-day bombardment of Fort McHenry on September 13-14, 1814, and fell inside the fort's walls. A defending officer later gave the spent shell to Michael Keyser as a relic of the battle that saved Baltimore. That same bombardment inspired Francis Scott Key to write the verses that became "The Star-Spangled Banner."

Laredo, TX

In March 1849, only months after the U.S.-Mexico War redrew the border along the Rio Grande, soldiers of the 1st U.S. Infantry threw up a star-shaped earthen fort on a bluff above the river and named it Camp Crawford, soon renamed Fort McIntosh. It anchored the young United States' newly won southern frontier, guarding river crossings and escorting travelers through contested borderlands. For decades the post housed troops through Indian campaigns, the Civil War era, and ongoing border unrest.

Beaver, PA · est. 1946

Built in 1778 during the Revolution, Fort McIntosh was the first military post the young United States raised north of the Ohio River, a foothold in contested Indian country. In 1785 it hosted the Treaty of Fort McIntosh, one of the early agreements by which the new republic pressed Native nations to cede lands in the Northwest Territory, and it also served as a base for surveying that opening frontier. The garrison was abandoned around 1790-91 as the line of settlement moved on.

Laredo, TX

By 1880 Fort McIntosh had grown from earthworks into a permanent brick garrison, and this surviving barracks — one of three built that year — quartered soldiers assigned to scouting and escort duty along the Rio Grande. Its four large rooms flanking a central stairway housed the enlisted men who patrolled a still-turbulent border in the decades after the Civil War. The building is the last of its trio to endure.

Roosevelt, TX

Laid out in 1852 and reopened when the frontier forts were reactivated after the Civil War, this road ran north and south between Forts Terrett, Clark, and McKavett, its route chosen chiefly for the water along the way. It carried mail, freight, troops, and a trickle of settlers, and served as a line of march for Colonel Ranald Mackenzie's campaigns against Native peoples to the northwest. After the forts closed in 1883, ranchers used stretches of it to drive cattle to market.

Menard, TX

Twenty-one miles west of this marker stood Fort McKavett, occupied by Confederate cavalry after secession to guard the frontier against Indian raids, and in early 1862 used to confine Union troops trying to leave Texas. Permanent forces withdrew that April when the defense line pulled back eastward, but scouting parties of Confederate and state troops kept using the post—often supplying their own horses, guns, and food—to shield settlements. It formed one link in a chain of posts set a day's ride apart from the Red River to the Rio Grande, honored here by a 1963 state memorial.

Philadelphia, PA · est. 1990

Laid out in 1771 by the British engineer John Montresor, Fort Mifflin guarded the Delaware River approach to Philadelphia. In the autumn of 1777 its small American garrison endured one of the fiercest bombardments of the Revolution, holding out against overwhelming British firepower until forced to abandon the ruins on November 15—buying precious time for Washington's army. Rebuilt around 1800 to a design associated with L'Enfant and enlarged in the nineteenth century, it served as a U.S. military post into the 1950s.

Oceanport, NJ

Fort Monmouth in Oceanport was for generations the home of the U.S. Army Signal Corps, the branch responsible for the Army's communications, radar, and electronics — technology that reshaped how twentieth-century wars were fought. Its Avenue of Memories lined a fort roadway with 117 trees and monuments, each honoring a Signal Corps soldier who died in action during World War II. After the historic post was decommissioned, those monuments were preserved rather than lost, and in November 2025 all 117 were rededicated together in Cowan Park.

Oceanport, NJ

For most of the twentieth century Fort Monmouth, on the New Jersey shore near Oceanport and Eatontown, was one of the Army's premier communications-electronics posts — long tied to the Signal Corps and the radar, radio, and battlefield-communications work that supported American troops abroad. This memorial gathers that legacy under two late-Cold-War campaigns named on the stone: Operation Just Cause, the December 1989 action in Panama, and Operation Desert Storm, the 1991 war to expel Iraqi forces from Kuwait. It honors both the soldiers and civilian personnel who deployed from the fort and the families who waited for them at home.

Shippensburg, PA · est. 1961

In the anxious summer of 1755, after General Braddock's crushing defeat on the Monongahela threw the Pennsylvania frontier open to French and allied Native raids, local settlers threw up a stockade here under James Burd and named it for provincial governor Robert Hunter Morris. Garrisoned by provincial troops under Hugh Mercer, it was one link in a chain of frontier forts meant to shield the exposed Cumberland Valley. Long after the timbers rotted, the soldiers' well still marked the spot a block north on Burd Street.

Muncy Township, PA · est. 2017

During the American Revolution, the West Branch Susquehanna Valley was a violent frontier, and Fort Muncy stood as the principal defensive post north of Sunbury. Built to shield settlers from raids, it was overrun by British forces and their Native allies in 1778, rebuilt and destroyed again in 1779, and raised a third time because its position was too important to abandon. From here scouting parties ranged out to guard a settler frontier caught in the wider war for independence.

Wharton Township, PA · est. 1946

In the spring of 1754 a young Virginia colonel named George Washington threw up a crude circular stockade in this soggy mountain clearing, aptly naming it Fort Necessity. On July 4 that year, outnumbered and surrounded by French and allied forces in the pouring rain, he was compelled to surrender — the only time in his life he ever did so. The skirmish here helped ignite the French and Indian War, a global conflict that reshaped North America.

Wharton Township, PA · est. 1926

In the Great Meadows just south of here, a 22-year-old lieutenant colonel named George Washington built a rough stockade he called Fort Necessity in the summer of 1754. Surrounded by a far larger force of French regulars and their Native allies under Coulon de Villiers, Washington and his raw Virginia and South Carolina troops fought a nine-hour engagement in the rain before surrendering, marching out with the honors of war on July 4, 1754.

Polk Township, PA · est. 1947

Fort Norris rose in 1756 as one of a string of frontier defenses Pennsylvania threw up during the French and Indian War, when raids drove settlers from their farms across the northern counties. Garrisoned by provincial troops, it served as a strongpoint and place of refuge in a landscape suddenly turned dangerous. The actual site stood about a mile from where the marker stands.

Cooks Point, TX

Fort Oldham was raised in 1836–37 by pioneers who sheltered with William Oldham, an infantry major in the Texas War for Independence. In seasons of Native raids dozens lived within its walls, and by 1838 it had a post office and stood on the Independence–Tenoxtitlan Road; Oldham himself later rode with the Somervell and Mier Expeditions, was captured by Mexican forces, and escaped to make his way home.

Marathon, TX

Established in 1880 in the rugged Big Bend country, Fort Peña Colorada guarded the water and passes near Marathon against raids across the Mexican border. Apaches struck the post in 1881 during the last years of the Indian Wars in far West Texas. With the frontier considered pacified, the fort was abandoned in 1893.

Stroudsburg, PA · est. 1967

Named for Governor John Penn and built to replace the abandoned Fort Hamilton, Fort Penn stood nearby as a provincial stronghold on the Pocono frontier. Garrisoned in 1763 amid renewed frontier warfare, it later became a haven for terrified settlers fleeing the raids that followed the Battle of Wyoming on July 3, 1778. In two different conflicts it served the same essential purpose: shelter on a dangerous frontier.

Hawley, TX

Fort Phantom Hill was established in 1851 as one of a chain of frontier posts, but its garrison abandoned it after barely two and a half years. The ruins found second lives—as a stop on the Southern Overland Mail before the Civil War and as a sub-post of Fort Griffin in the early 1870s—while a lively village grew up nearby, even serving briefly as Jones County's seat in 1881 before fading away.

Anson, TX

When Texas seceded, Confederate and state troops took over abandoned Fort Phantom Hill as an outpost guarding the frontier against Indian raids while the state's men were away at war. In 1862 the defense line was pulled back thirty miles east, but patrols kept ranging out—often on their own horses, guns, and provisions—to protect settlements and watch for Union incursion. The marker honors Texans who held a 2,000-mile line of coast and frontier with the few men the Confederacy could spare.

Indiana Township, PA · est. 1959

This blockhouse, a small defensive redoubt, was built in 1764 by Colonel Henry Bouquet as one of the outworks guarding Fort Pitt near its western bastions. It rose in the tense years after the French and Indian War, when British control of the forks of the Ohio was still contested during Pontiac's War. Today it is the only surviving structure of the great fort that once commanded this strategic point.

Erie, PA · est. 1946

Guarding the Lake Erie end of the strategic portage to the Ohio Valley, Fort Presque Isle changed hands as European empires fought for the continent. The French built it under Marin in 1753 and abandoned it in 1759; a British fort raised by Colonel Bouquet in 1760 fell to Pontiac's warriors in 1763. From here the French Road ran inland to Fort LeBoeuf, a chain of posts binding the lake to the Ohio country.

Sierra Blanca, TX

Sixteen miles southwest along the Rio Grande, on the old military and stage road from San Antonio to El Paso, Fort Quitman anchored the Confederate far western frontier after U.S. posts were surrendered in 1861. Occupied by Texas mounted rifles, it sat on the supply and communication line for the 1861–62 Confederate campaign to reach the Pacific through Arizona and New Mexico, and was briefly held by Union troops from California in 1862. From here, thinly manned camps a day's ride apart guarded a 2,000-mile frontier for the western Confederacy.

Lock Haven, PA · est. 1947

On the exposed western edge of colonial settlement, William Reed's stockaded house stood as the farthest line of defense for families along the Susquehanna's West Branch. In an era of frontier raids, such fortified homesteads gave scattered pioneers a place to shelter when danger threatened. A monument near the bridge now marks where this pioneer outpost once guarded the valley.

Jacksboro, TX

Established by the U.S. War Department in November 1867, Fort Richardson stood as the northernmost of a chain of posts guarding the Texas frontier against raids in the years after the Civil War. It was named for General Israel B. Richardson, mortally wounded at Antietam in 1862. As settlement pushed westward the fort's purpose faded, and it was abandoned in 1878; what stands here was partially reconstructed in 1936.

Jacksboro, TX

Built by the U.S. Army in 1867, Fort Richardson anchored the northernmost line of federal posts guarding Texas settlers during the Indian Wars that followed the Civil War. The site had already known travelers as a stop on the Butterfield Overland stage route in the years before secession. Garrisoned troops rode from here on patrols across a contested frontier until the post was abandoned in 1879 as the fighting moved west.

Jacksboro, TX

Part of Fort Richardson, built in 1867 to shield North Texas settlers, this post hospital witnessed a pivotal moment in frontier justice. In May 1871 General William Tecumseh Sherman was inspecting the fort when word came of the Warren Wagon Train massacre 24 miles away. The accused, tracked to Fort Sill, were brought to Jacksboro for trial — the first time Native men were tried in a white civilian court in North Texas.

Rio Grande City, TX

Established in 1848 at Davis Landing on the Rio Grande, this post was named for Major David Ringgold, mortally wounded at the Battle of Palo Alto in 1846 during the Mexican-American War. Its garrison came and went through the mid-19th century—abandoned in 1861, reoccupied after the Civil War—and a young Robert E. Lee passed through in 1856 and 1860 while stationed in Texas. The State of Texas marked the site in 1936.

Rio Grande City, TX

Early in the Civil War, Confederate Texans under Col. John S. Ford occupied Fort Ringgold on the Rio Grande, a vital link in the chain of posts guarding Texas's vast frontier, coastline, and border. From here commanders like Ford, August Buchel, and Santos Benavides scouted the river, defended ranches, and protected the cotton wagons trading through neutral Mexico for war supplies. Union cavalry seized the fort in late 1863, but Ford retook it in May 1864 and used it as a springboard to recapture Brownsville.

Antis Township, PA · est. 1947

During the American Revolution, frontier Pennsylvania needed lead for musket balls, and the Sinking Valley mines offered a rare domestic source. In 1778 Daniel Roberdeau built a fort here to guard those mines and the miners who supplied the Continental army. The stockade, sometimes called Fort Roberdeau or the "Lead Mine Fort," stood a few miles from this marker.

Northeast Madison Township, PA · est. 1947

In 1755, as the French and Indian War set the Pennsylvania frontier ablaze, settlers in the Sherman's Valley threw up a fortified stronghold on George Robinson's land. Fort Robinson was one of a chain of rough private and provincial forts where scattered farm families could shelter when war parties swept through. For several harrowing years it served as a place of refuge on an exposed and dangerous frontier.

Sabine Pass, TX

When war came in 1861, the citizens of Sabine City formed a Committee of Safety and, with enslaved and free labor, raised a dirt-and-timber earthwork to guard the strategic Sabine Pass channel into East Texas and western Louisiana. In September 1862 a Union steamer and two schooners battered the fort; with only about sixty defenders and yellow fever spreading, Confederate Major Josephus S. Irvine spiked the guns and abandoned it. Lessons from its fall shaped nearby Fort Griffin, site of the famous 1863 Confederate victory at Sabine Pass.

Niles, MI

Fort St. Joseph stood here from 1691 to 1781, a French outpost planted deep in the Great Lakes fur-trade country and among the region's Native nations. Over ninety years it passed through French, British, and briefly Spanish hands, and in 1781 a Spanish-led raiding party captured the post—an episode tied to the wider American Revolution far to the east. Its long span makes this ground a crossroads of imperial rivalry on the western frontier.

Saint Louis, MO

In 1780, during the American Revolution, Spain held St. Louis as part of its Louisiana territory. When a British-led force of allied Native warriors struck on May 28, the small Spanish garrison under Captain Fernando de Leyba beat back the assault from fortifications like Fort San Carlos, in what became known as the Battle of St. Louis.

Shirleysburg, PA · est. 1947

Built in 1755–56 by the frontier trader and Indian agent George Croghan, Fort Shirley began as a stockade and grew into a key link in the chain of forts guarding Pennsylvania's frontier west of the Susquehanna River during the French and Indian War. In 1756 it served as the base for Colonel John Armstrong's expedition against the Delaware village of Kittanning. Its role reflected the desperate effort to defend backcountry settlers from raids during that conflict.

Shirleysburg, PA · est. 1926

This knoll carried Fort Shirley, one of the frontier forts raised in 1756 during the French and Indian War, built by the noted Indian trader and agent George Croghan on the site of his earlier trading post at Aughwick. Two years before, in 1754, Croghan's post here hosted a council in which interpreter Conrad Weiser met the Iroquois "Half King" Tanacharison and chiefs of the Shawnee and Delaware. The place thus joined the twin frontier worlds of diplomacy and defense.

Fort Smith, AR

"Our Confederate Dead, 1861–1865" — this memorial in Fort Smith honors the western Arkansas men who died fighting for the Confederacy during the Civil War. A frontier river town on the edge of Indian Territory, Fort Smith sat at a strategic crossroads that both armies contested.

Port Huron, MI

Around 1686 the French explorer Daniel Greysolon, Sieur du Lhut (Duluth), built a fort near this site to guard the vital waterway joining Lake Erie and Lake Huron. Described as the second European settlement in lower Michigan, the post asserted French control over a strategic chokepoint in the fur-trade routes of the Great Lakes. It stood in a contested borderland long before American settlement arrived.

Inez, TX

In 1685 the French explorer René-Robert Cavelier, Sieur de La Salle, planted the first European settlement in Texas near here, only to have it collapse under hardship and attacks by the Karankawa people; a Spanish expedition under Alonso de León burned its ruins in 1689. On the same ground the Spanish later raised Presidio La Bahía to guard Mission Espíritu Santo, part of a mission-presidio system that moved twice more before settling at Goliad in 1749. The site witnessed the collision of French ambition, Spanish empire, and Native power on the Gulf coast.

Huntingdon, PA · est. 1955

Fort Standing Stone once guarded this bend of the Juniata River where Stone Creek joins it, throwing up a stockade against raids on the exposed frontier. In July 1778, at the height of the Revolutionary War, Continental troops and militia were ordered here as part of a broader plan to defend the backcountry from attacks. The old fort stood a short distance south of this marker; the settlement it protected grew into Huntingdon.

Fort Stockton, TX

Fort Stockton guarded the West Texas frontier from its founding in 1859, was abandoned during the Civil War, and was reestablished in 1867, when this locally quarried stone guard house went up. Its lumber hauled by oxcart from distant Indianola, the building held a guardroom, arm and leg irons, and a dungeon for solitary confinement before the fort was abandoned in 1886.

Ft. Stockton, TX

When the U.S. Army rebuilt Fort Stockton in 1867 to guard the road to El Paso, it raised seven adobe-and-stone houses for officers' families facing the parade ground. Complete with corrals and carriage stalls, these quarters served until the fort closed in 1886. Three of the residences still stand today.

Ft. Stockton, TX

After Federal troops abandoned it at the start of the Civil War, Fort Stockton was occupied by the 2nd Regiment Texas Mounted Rifles as part of the Confederacy's far-western defense line and its bid to reach the Pacific through the Arizona–New Mexico campaign of 1861–62. Comanche and Apache activity centered on the area, and California Union troops came to dominate the region from 1862 to 1865. The post also drew Union sympathizers and others hoping to escape the war.
