Fort McHenry Bombardment Relic
Baltimore, Baltimore, Maryland
Marker Inscription
This bomb was fired from a British warship during the bombardment of Fort McHenry September 13 and 14,1814 and fell inside the fort it was presented to Michael Keyser by an officer of the fort. The rack on which it rests was used to bend bar iron so that it could be advantageously loaded into the old Conestoga wagons before wagon transportation, had been superseded by railroads.
Erected by Michael Keyser
The Story
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."
Why it matters
It is a tangible relic of the War of 1812 defense of Baltimore, the fight that gave rise to the national anthem.
The story behind this marker
AI contextThe era
In the late summer of 1814, the young United States was fighting for its life in a war it had nearly lost. British forces had already marched on Washington and burned the public buildings of the capital, and now they turned toward Baltimore — a booming, defiant port city and a prize the British badly wanted to humble. Baltimore's harbor was guarded by Fort McHenry, a star-shaped brick fortress whose guns commanded the water approach to the city.
This was the Early Republic, a nation barely a generation removed from its founding and still unsure it would survive among the great powers. The War of 1812 had gone badly in many places, and the fall of a city as important as Baltimore could have been catastrophic for American morale.
Into this tense moment, on September 13 and 14, 1814, came one of the most famous bombardments in American history — and, as this marker reminds us, the age it belonged to was one still moving goods by horse and wagon, before the railroads that would soon transform the country had taken hold.
People & events
For roughly a day and a night, British warships hurled shells and rockets at Fort McHenry, trying to pound its defenders into surrender so their army could take the city. The fort held. When the smoke cleared on the morning of the fourteenth, the American flag was still flying, and the British broke off their assault on Baltimore.
This particular relic is one small, heavy witness to that ordeal: an iron bomb that was fired from a British warship and fell inside the fort's walls without doing its intended work. Afterward, an officer of the fort gave the spent shell to a man named Michael Keyser as a keepsake of the battle — the kind of personal, tangible memento by which ordinary people held onto history.
The rack beneath it tells a quieter story about the same era. It was a tool used to bend bar iron so that heavy loads could be packed efficiently into Conestoga wagons — the great freight wagons that moved American goods overland before railroads made them obsolete. Together, shell and rack fix the object in a specific vanished world.
Its place in the American story
The defense of Fort McHenry became one of the founding legends of American identity, because of what one witness did with what he saw. An American who watched the bombardment from a distance was so moved by the sight of the flag still flying at dawn that he set down the verses that would eventually become "The Star-Spangled Banner," the national anthem. Few battles anywhere have produced a more lasting cultural echo.
That is why a plain iron shell like this one carries such weight. It is not a symbol invented later; it is a physical piece of the actual bombardment that inspired the song — the very thing being fired at the fort while the flag endured.
The relic's mounting deepens the national story in an unexpected direction. By pairing the battle with a tool of wagon-era freight, it captures the United States at a hinge point: a nation that had just proven it could defend itself, standing on the edge of the transportation revolution that would knit it together and carry it westward.
If you visit
This is a marker best appreciated slowly, because it asks you to read an object rather than a plaque. Look first at the shell itself — its size and heft — and imagine it arcing out of a warship's mouth and falling among the defenders of a fort under fire.
Then let your eye drop to the rack it rests on, and remember what it was for. There is something quietly powerful about a war relic displayed on a piece of everyday working iron: the drama of the battle and the ordinary labor of the age, side by side.
Baltimore wears its War of 1812 history proudly, so this pairs naturally with a broader visit to the city's harbor and its stories of the star-spangled morning. Bring a little imagination and a sense of scale, and this modest relic will do what the best of them do — collapse two centuries into the space of a single, heavy object you can stand in front of.

War of 1812 Bomb & Rack
Baltimore, MD
On display here is a British bomb — a mortar shell — fired at Fort McHenry during the British bombardment of September 13–14, 1814. For roughly a day and a night, Royal Navy ships hurled shells and rockets at the fort guarding Baltimore harbor; the American flag still flying at dawn inspired Francis Scott Key to write the words that became 'The Star-Spangled Banner.' This relic makes the War of 1812 tangible — a piece of ordnance from the night a national anthem was born.
Great Railroad Strike of 1877
Baltimore, MD
In the depths of the long depression that followed the Panic of 1873, railroad companies slashed already-thin wages one time too many, and in July 1877 the anger boiled over. What began among Baltimore and Ohio Railroad workers in Martinsburg, West Virginia, and here in Baltimore quickly leapt from city to city along the rail lines, becoming the first genuinely nationwide strike in American history. For roughly six weeks, freight sat idle, factories fell silent, and clashes between strikers, militia, and federal troops left dozens dead before the movement was suppressed.
The Fell Family Cemetery
Baltimore, MD
In the maritime heart of Baltimore lies the small burial ground of the Fell family, the English settlers who gave their name to Fell's Point. Arriving in the eighteenth century, the Fells laid out a shipbuilding and shipping community along the deep water of the Patapsco River, and their surname still marks one of the city's oldest and most storied neighborhoods. This family plot is a quiet reminder that a bustling seafaring district began with a single household's land and ambitions.
Fells Point
Baltimore, MD
Fells Point was founded in 1726 by Lancashire shipbuilder William Fell, and its deepwater shoreline quickly made it one of early America's great shipbuilding centers. From colonial times through the Civil War, more than six hundred vessels slid down its ways, including the frigate USS Constellation and the swift, raking-masted Baltimore clippers that made the port famous. The neighborhood grew into a bustling maritime community at the heart of Baltimore's rise.
