Fort McHenry and the Battle of Baltimore 1814: How Baltimore's Defense Saved the Republic
In September 1814, three weeks after British forces had burned Washington DC, a British naval and land expedition sailed up the Patapsco River intending to capture Baltimore as the next major American city. The fall of Baltimore, the third-largest US city at the time and the home port of the Baltimore Clipper privateers that had been devastating British shipping for two years, would have been a far more strategically consequential blow than the burning of Washington — Washington was a small administrative capital; Baltimore was a major commercial and military port whose loss would have crippled the American war effort in the Chesapeake.
The British failed. The combined defense of Fort McHenry, the militia stand at the Battle of North Point, and the well-prepared Baltimore fortifications turned back both the naval and land assaults. The 25-hour British bombardment of Fort McHenry, observed from a British warship by the American lawyer Francis Scott Key during prisoner-exchange negotiations, produced the lyric "Defence of Fort M'Henry" that became — set to a popular British drinking-song melody — the song that the United States Congress would, more than a century later in 1931, designate as the national anthem.
This guide walks the strategic context, the battle itself, the visit experience at Fort McHenry today, and the secondary historical sites around Baltimore that round out the 1812 history.

Strategic Context: Why Did the British Want Baltimore?
The War of 1812 between the United States and Great Britain had multiple causes — British impressment of American sailors, British support for Native American resistance to American expansion in the Ohio Valley, and American resentment of British trade restrictions during the Napoleonic Wars. By 1814, with Napoleon defeated in Europe and the British able to redirect substantial forces to North America, the war entered a new phase. The British strategy in 1814 included:
- Coastal raids on the American Atlantic seaboard to force the United States to defend a long coastline with limited military resources
- Capture of major American cities including Washington DC, Baltimore, New Orleans, and potentially New York
- Naval blockade of American ports to strangle American commerce and revenue
- Support for Indigenous resistance along the Canadian border and in the Northwest
Baltimore was a particular target for two reasons. First, Baltimore Clipper privateers — fast, agile sailing ships with raked masts — had captured over 500 British merchant vessels during the war, more than any other American port. The British called Baltimore "a nest of pirates" and considered destroying its commercial capacity essential to victory. Second, Baltimore was a logical follow-on target after Washington DC: the British forces were already on the Chesapeake Bay; the city was substantial enough to deliver a significant strategic blow if captured; and its capture would establish British control over the upper Chesapeake and lower Susquehanna for the duration of the war.
The British force assembled for the Baltimore expedition included approximately 5,000 land troops under Major General Robert Ross and a substantial fleet of warships under Vice Admiral Sir Alexander Cochrane, along with the smaller fleet of Vice Admiral Sir George Cockburn that had been operating in the Chesapeake throughout the summer.
Baltimore's Defense Preparations
The Baltimore defense was organized by Major General Samuel Smith (a Maryland militia officer and US Senator who had served in the Revolutionary War). Smith began intensive preparations in August 1814, immediately after Washington fell. The Baltimore defense plan included:
Land fortifications along the eastern approaches to the city — the militia would meet any British land assault on the Patapsco peninsula, between North Point and Baltimore, well east of the city. The fortifications included earthworks, abatis (felled trees with sharpened branches), and prepared firing positions for militia musketmen and artillery.
Naval defense at the entrance to the Inner Harbor. Smith ordered the deliberate scuttling of approximately 22 merchant ships in the channel between Fort McHenry and the Lazaretto Battery on the opposite shore. The sunken ships formed a chevaux-de-frise that prevented British warships from sailing past Fort McHenry into the Inner Harbor.
Fort McHenry itself was reinforced and re-armed. The garrison was approximately 1,000 men under the command of Major George Armistead (a US Army regular officer). The fort's walls — a star-shaped masonry structure built between 1798 and 1803 — were reinforced with earth bermings; substantial artillery (24-pounder cannon, 32-pounder cannon, mortars) was emplaced along the bastions; and the fort's interior was prepared for sustained bombardment with bomb-shelter trenches and powder magazine protection.
A particular preparation, often retold: in the summer of 1813, Major Armistead had commissioned Mary Pickersgill — a Baltimore flag-maker — to produce a giant garrison flag for Fort McHenry. The flag, 30 feet by 42 feet, included 15 stars and 15 stripes (the official US flag in 1814 included 15 of each, representing the original 13 colonies plus Vermont and Kentucky). The flag was deliberately oversized — Armistead wanted "a flag so large that the British will have no difficulty in seeing it from a distance." Mary Pickersgill and her family produced the flag at her Pratt Street home (now the Star-Spangled Banner Flag House Museum), and it was raised at Fort McHenry in August 1813.
The Battle: September 12-14, 1814
Land Assault: Battle of North Point (September 12)
On the morning of September 12, 1814, British troops landed at North Point, fourteen miles east of Baltimore on the eastern peninsula of the Patapsco. General Ross began marching west toward Baltimore.
Maryland militia under Major General John Stricker had occupied prepared positions at Bear Creek and the Long Log Lane — chokepoints along the route the British had to traverse. As the British advance guard approached Stricker's position, militia riflemen fired from concealed positions in the woods. General Robert Ross — the British commander — was killed in this initial engagement, struck in the chest by an American rifle shot from the woods near the modern site of the Battle of North Point Monument.
Command of the British land force fell to Colonel Arthur Brooke. Brooke continued the advance, eventually pushing through Stricker's main militia line in a sustained engagement. The Battle of North Point resulted in approximately 300 British and 200 American casualties. Stricker's militia retreated in good order to inner defensive positions near Hampstead Hill (the modern Patterson Park area, then the eastern edge of Baltimore).
By the evening of September 12, Brooke's forces were within 2 miles of Baltimore but facing prepared American positions at Hampstead Hill manned by approximately 15,000 Maryland militia plus US Army regulars and artillery. The American positions were strongly entrenched and had clear fields of fire across the open ground between the British and the city.
Naval Bombardment: September 13-14
While the land assault was developing, Vice Admiral Cochrane initiated the naval bombardment. The British fleet — 19 warships including five bomb ships (mortar-vessels designed for shore bombardment) and rocket-vessels — sailed up the Patapsco and took position approximately 2 miles from Fort McHenry on the morning of September 13.
The bombardment began at approximately 6:30 AM on September 13 and continued for approximately 25 hours, ending about 7:30 AM on September 14. The British fired approximately 1,500 to 1,800 mortar shells, rockets, and round shot at Fort McHenry across the period of bombardment.
The bombardment was conducted from outside the effective range of Fort McHenry's main artillery — the British bomb ships had longer range than the fort's cannon. This meant that the American defenders could not return fire effectively for most of the bombardment. The fort's role was to endure the bombardment without surrender; the strategic effect of the bombardment depended entirely on whether the fort would surrender or hold.
Fort McHenry casualties were remarkably low. Four American soldiers killed and approximately 24 wounded during the 25 hours of bombardment. The fort's defensive design — the masonry walls, the earth bermings, the bomb shelters — successfully reduced the bombardment's effects to manageable levels.
The Storm: September 13 night
A late afternoon and overnight thunderstorm on September 13-14 added to the bombardment's drama. Heavy rain reduced the visibility of the fort and made the British rocket-attacks (which depended on flammable materials) less effective. The lightning illuminated the fort intermittently, and the ongoing artillery fire combined with thunder and lightning produced what observers described as one of the most extraordinary scenes any American had witnessed.
The Storm Flag and the Garrison Flag
A detail often misunderstood: during the bombardment itself, the smaller "storm flag" — about 17 feet by 25 feet — was flying at Fort McHenry rather than the giant 30-by-42-foot garrison flag. The smaller storm flag was used during heavy weather to protect the larger and more delicate garrison flag from rain damage.
When the bombardment ended on the morning of September 14, Major Armistead ordered the storm flag lowered and the giant garrison flag raised — symbolically declaring that Fort McHenry had survived and continued to defy British attack. This raising of the giant flag at dawn on September 14 was the moment that Francis Scott Key observed from the British warship and that inspired his lyrics.
The British Withdrawal
With Fort McHenry undefeated, the prepared American positions at Hampstead Hill blocking land approach to Baltimore, and General Ross dead, the British command decided that continuing the assault would cost more than the expected gain. Colonel Brooke withdrew the British land forces back toward North Point on September 14, and the British fleet sailed back down the Patapsco to rejoin the larger British Chesapeake fleet.
The British did not return to attack Baltimore. The Baltimore defense had succeeded.
Francis Scott Key and the Lyrics
Francis Scott Key was a 35-year-old American lawyer from Georgetown who had been negotiating the release of an American civilian prisoner — Dr. William Beanes, a Maryland physician who had been arrested by British forces during the Washington DC raid. Key negotiated successfully with the British command for Beanes's release; however, the British detained both Key and Beanes aboard a British warship for the duration of the Baltimore operation, since they had observed British plans and could not be allowed to return to American lines until after the attack.
Key spent the night of September 13-14 aboard the British truce ship HMS Surprize (or possibly the British frigate HMS Tonnant — historical sources disagree on the specific vessel), watching the bombardment of Fort McHenry from approximately 8 miles distant. As the bombardment continued through the night, Key did not know whether Fort McHenry would survive. The dawn revelation — the giant garrison flag still flying — produced the famous opening lines:
O say can you see, by the dawn's early light, What so proudly we hail'd at the twilight's last gleaming, Whose broad stripes and bright stars through the perilous fight O'er the ramparts we watch'd, were so gallantly streaming?
Key wrote the four-stanza poem on the back of a letter while still aboard the British ship and on the boat that returned him to Baltimore on September 14. The poem was first published as a broadside on September 17, 1814, three days after the battle, under the title "Defence of Fort M'Henry."
The lyrics were quickly set to "To Anacreon in Heaven" — a popular British drinking-song melody by John Stafford Smith that was already widely sung in American taverns — and the song became "The Star-Spangled Banner." It was popular through the 19th century but did not become the official US national anthem until March 3, 1931, when President Herbert Hoover signed legislation designating it as such.
Visiting Fort McHenry Today
Fort McHenry National Monument and Historic Shrine is administered by the National Park Service and sits at 2400 East Fort Avenue in Locust Point, Baltimore, on the peninsula at the entrance to the Inner Harbor. The fort is a 5-minute drive from downtown Baltimore (via Locust Point) or about 20 minutes by Charm City Circulator bus and walk.
What to See
The Fort. The masonry star-fort survives substantially as it existed in 1814, with reinforced walls, restored bastions, and the historical artillery emplacements. The walls are walkable; visitors can stand at the position from which Major Armistead and the garrison observed the British fleet during the bombardment.
The Visitor Center. Recently renovated, the visitor center houses substantial exhibits on the battle, Mary Pickersgill's flag, the Star-Spangled Banner lyrics, and the broader War of 1812 context. A 10-minute orientation film is shown in the visitor center theater. The center is well-designed for both adult and family visitors.
The Garrison Flag. A reproduction of the giant garrison flag flies at the fort. Visitors can frequently see National Park Service rangers participating in flag-raising and flag-lowering ceremonies, when present.
The Original Garrison Flag itself — the actual 30-by-42-foot flag that flew at Fort McHenry on September 14, 1814 — is preserved at the Smithsonian National Museum of American History in Washington DC. The flag survived in private hands (descendant family of Major Armistead) until donated to the Smithsonian in 1912; it has been substantially restored and is on display in the museum's permanent exhibition. For visitors making a Baltimore-DC trip, seeing both the fort and the original flag is a complete experience.
The Patapsco Battlefield View. The fort sits at the entrance to the Inner Harbor, and the bay view from the fort's water-side walls clearly shows the location of the British fleet during the bombardment. The scale of the bombardment becomes clearer from this position than from any reading.

Annual Defenders Day Commemoration
Every September on the second Saturday of the month, Fort McHenry hosts Defenders Day — Baltimore's annual commemoration of the Battle of Baltimore. The events include:
- Reenactor demonstrations in 1812-period uniforms
- Cannon firings and small-arms demonstrations
- Music and educational programming
- Evening fireworks over the Inner Harbor
For visitors who can plan their Baltimore trip around Defenders Day, the experience is among the most distinctive American historical events.
The Patapsco Approach: Routes to Follow
For visitors interested in the broader battle geography, several locations beyond Fort McHenry are worth visiting.
North Point Battlefield (North Point State Park) — fourteen miles east of downtown Baltimore on the Patapsco peninsula. The state park preserves the area where the British landed and where the Battle of North Point was fought on September 12, 1814. The General Ross Monument at the park marks the approximate location where the British commander was killed. The drive from Fort McHenry to North Point is about 25 minutes.
Patterson Park / Hampstead Hill (Patterson Park) — one mile east of downtown Baltimore. The park is the modern site of Hampstead Hill, the prepared American defensive position where 15,000 militia and regulars waited for the British land assault that never came. The Pagoda in the park (1891) sits at approximately the highest point of the historical defensive line. Walking from Patterson Park east toward North Point along Eastern Avenue retraces (in reverse) the route the British advance would have taken if they had pressed through to the city.
Star-Spangled Banner Flag House Museum (Star-Spangled Banner Flag House) — at 844 East Pratt Street, this is the home where Mary Pickersgill sewed the giant garrison flag in summer 1813. The house has been preserved as a museum, with original Pickersgill family rooms, exhibits on the flag's construction, and historical context for the broader 1812 era. The museum is a 5-minute drive from Fort McHenry and an essential complement to the fort visit.
Lazaretto Battery — the small fortification on the opposite shore from Fort McHenry that worked in tandem with the fort to control the harbor entrance. The Lazaretto site (on Boston Street near the modern bridge to Canton) is partially preserved with interpretive signage, though less visited than Fort McHenry.
Westminster Hall and Burying Ground — where many Baltimore defenders are buried. Edgar Allan Poe is also buried here, but the cemetery's significance for the 1812 era includes the graves of John Stricker (commander at North Point), other militia officers, and Baltimore citizens who participated in the city's defense.
Why Baltimore's Defense Mattered
The Battle of Baltimore was, in some sense, the turning point of the War of 1812. With the British failure to capture Baltimore, the British strategic initiative in the Chesapeake was effectively ended. The British attempted other operations in 1814-1815 (the Battle of New Orleans on January 8, 1815, was a decisive American victory that effectively ended the war), but the Chesapeake campaign that had begun with the burning of Washington was over.
If the British had captured Baltimore in September 1814, the American war effort would have been crippled. Major commercial activity, the Maryland militia organization, and substantial American naval capacity (the privateers operating from Baltimore) would all have been disrupted. The American government, having already retreated from Washington, would have been forced to seek peace on much less favorable terms than it eventually obtained at the Treaty of Ghent in December 1814.
The Baltimore defense — the combined effect of the prepared land fortifications, the Patapsco channel obstruction, and the unyielding hold of Fort McHenry through the 25-hour bombardment — preserved the American capacity to negotiate from strength.
The cultural legacy is the Star-Spangled Banner. The strategic legacy is American sovereignty over the Chesapeake and the larger eastern seaboard, sustained through the war's final months and into the post-war era when American territorial expansion accelerated dramatically. Both legacies trace directly to the events at Fort McHenry on September 13-14, 1814.
