Short Answer
How to Read This Timeline
The war unfolded across several theaters at once. A victory on Lake Erie did not settle the Niagara campaign, and the capture of Washington did not determine what happened at Baltimore.
Dates below identify principal events rather than every skirmish. Where a campaign unfolded over several days or months, the entry uses a date range. The Creek War appears because it intersected with the wider conflict, while retaining its own Indigenous political divisions and causes.
“Canada” is used as geographical shorthand. During the war, the territories later forming Canada were British colonies, rather than the modern Canadian state. Indigenous nations pursued distinct interests and should not be treated as a single side with a uniform policy. [^40][^4]
1807: Maritime Confrontation and Economic Retaliation
June 22, 1807 — The Chesapeake–Leopard Affair
HMS Leopard fired on USS Chesapeake off the Virginia coast after demanding the surrender of alleged British naval deserters. British personnel boarded the American frigate and removed four men. Three American crew members were killed and eighteen wounded.
The attack made disputes over impressment and sovereignty especially visible. Yet war did not follow immediately: the United States continued trying diplomatic and economic measures for another five years. [^5]
November–December 1807 — Commercial Warfare Intensifies
Britain’s Orders in Council and Napoleon’s Milan Decree tightened restrictions on neutral commerce. The United States sought to trade without entering the European war, but American ships faced competing British and French demands.
These measures connected the future War of 1812 to the Napoleonic struggle. American grievances developed partly because both European powers treated neutral trade as a resource their opponent should be denied. [^6]
December 22, 1807 — The Embargo Act Becomes Law
President Thomas Jefferson approved the Embargo Act, restricting American overseas commerce in an attempt to pressure Britain and France.
The policy aimed to defend American rights without war. Its domestic costs, particularly for shipping and export interests, made it deeply divisive. Economic coercion became part of the road to war because its disappointing results encouraged arguments for stronger action. [^7][^8]
1808: Resistance Builds on Land and at Home
1808 — Tecumseh and Tenskwatawa Establish Prophetstown
The Shawnee brothers Tecumseh and Tenskwatawa established a major center of their movement near the Wabash and Tippecanoe rivers.
Tecumseh sought cooperation among Native nations to resist dispossession, while Tenskwatawa supplied religious and cultural leadership. Their movement had independent objectives rooted in Indigenous homelands; it did not originate simply as a British instrument against the United States. [^9]
1808 — Opposition to the Embargo Grows
American merchants and other commercial interests challenged the restrictive system. Enforcement problems and economic hardship weakened confidence that withholding trade would secure concessions.
The resulting disagreement foreshadowed wartime divisions. Americans could agree that European interference was harmful while disagreeing sharply over whether embargoes, negotiation, or military action offered the best response. [^8]
1809: A New President and Continued Trade Disputes
March 1809 — The Non-Intercourse Act Replaces the Embargo
Congress replaced the broad embargo with restrictions aimed at Britain and France, allowing commerce with other countries.
This adjustment reduced the scope of American economic pressure but did not settle the underlying dispute. Trade policy remained a contested instrument of foreign relations. [^6]
March 4, 1809 — James Madison Becomes President
Madison inherited unresolved maritime grievances and a troubled commercial policy. His administration would have to choose whether to continue economic restrictions, negotiate further, or prepare for war.
The change of president did not reset the relationship with Britain. Several years of accumulating distrust shaped the choices available to the new administration. [^6]
1810: Another Attempt at Commercial Pressure
May 1810 — Macon’s Bill No. 2
Congress reopened trade with Britain and France while creating an incentive for either power to stop interfering with American commerce. A change by one could lead to renewed American restrictions against the other.
Napoleon’s assurances persuaded Madison to direct commercial pressure toward Britain. French conduct remained problematic, but the policy helped narrow the immediate diplomatic confrontation. [^6]
1811: Naval Violence and Frontier Escalation
May 16, 1811 — The President–Little Belt Affair
USS President fought the smaller British warship HMS Little Belt. The encounter arose amid American anger over the seizure of sailors and added another violent incident to the maritime dispute.
The episode also complicates any account in which escalation came entirely from one side: American naval action contributed to the worsening relationship. [^10]
November 7, 1811 — The Battle of Tippecanoe
William Henry Harrison advanced toward Prophetstown while Tecumseh was away. Forces associated with Tenskwatawa attacked Harrison’s camp, and American troops subsequently destroyed the settlement.
The battle weakened the movement’s immediate base but intensified the frontier conflict. It also helped drive Tecumseh toward closer cooperation with Britain, reinforcing the connection between Indigenous resistance and the approaching Anglo-American war. [^11][^12]
1812: War Begins and American Invasions Falter
June 1–18, 1812 — The United States Declares War
On June 1, Madison presented Congress with grievances against Britain. The House approved a declaration on June 4 by 79 votes to 49. The Senate approved it with amendments on June 17 by 19 votes to 13.
Madison signed the legislation on June 18. The votes reveal substantial opposition: the declaration reflected a governing majority, not national unanimity. [^13]
June 23, 1812 — Britain Announces Revocation of Key Orders in Council
Britain announced the removal of important commercial restrictions affecting American vessels, with the change scheduled to operate from August 1 under stated conditions.
The announcement came five days after the American declaration. It did not automatically settle impressment or other grievances. Slow communication complicated a potential opening for compromise. [^14]
July 17, 1812 — British and Indigenous Forces Capture Fort Mackinac
An expedition of British personnel, local traders, and Indigenous warriors captured the American fort on Mackinac Island.
The American garrison had not received timely notice of the declaration. The loss demonstrated the military importance of communication, local alliances, and control of the upper Great Lakes. [^2]
August 16, 1812 — Detroit Surrenders
American General William Hull surrendered Detroit to forces led by Isaac Brock and Tecumseh.
The capitulation reversed American hopes for a quick victory in the northwest. It strengthened British and Indigenous positions and damaged confidence in the American invasion effort. [^15]
August 19, 1812 — Constitution Defeats Guerriere
USS Constitution, commanded by Isaac Hull, defeated HMS Guerriere in the Atlantic. The action became associated with the American frigate’s celebrated nickname, Old Ironsides.
The victory supplied a morale boost after setbacks on land. It showed that American frigates could win individual engagements without establishing American control of the oceans. [^16]
October 13, 1812 — The Battle of Queenston Heights
American troops crossed the Niagara River but failed to secure a lasting foothold. British, Canadian, and Indigenous forces defeated the invasion.
Isaac Brock was killed during the fighting. His death and the successful defense became important elements of Canadian remembrance. [^17]
December 29, 1812 — Constitution Defeats Java
Under William Bainbridge, Constitution defeated HMS Java off Brazil.
The action reinforced the reputation of American heavy frigates. Nevertheless, naval prestige and isolated victories could not solve the United States’ larger problems of invasion planning, supply, and British maritime superiority. [^16]
1813: Great Lakes Victories and Failed Advances on Montreal
January 18–23, 1813 — The River Raisin Battles and Aftermath
American forces gained an initial success at Frenchtown on January 18. British and Indigenous forces defeated them on January 22. On January 23, some Indigenous warriors killed wounded American prisoners who had been left behind.
The events became associated with the rallying cry Remember the Raisin. They intensified hostility and demonstrated the vulnerability of American operations intended to recover Detroit. [^18]
April 27, 1813 — American Forces Capture York
American troops captured York, the capital of Upper Canada and the location of present-day Toronto. An explosion of the British magazine mortally wounded American commander Zebulon Pike.
American forces subsequently burned public buildings. The raid illustrates how the war increasingly exposed communities and civilian property to destruction, while failing to provide a lasting conquest. [^43]
Late April–Early May 1813 — The First Siege of Fort Meigs
British, Canadian, and Indigenous forces besieged Fort Meigs on Ohio’s Maumee River. American troops sustained serious losses in fighting associated with the siege, but the fort held.
Its survival helped preserve the American position in the northwest. The outcome was not a simple measure of casualties: retaining the fortified base mattered to later operations. [^17]
May 27, 1813 — Americans Capture Fort George
An American amphibious attack forced the defenders to abandon Fort George near the mouth of the Niagara River.
The success offered an opportunity to advance farther into Upper Canada. Subsequent defeats prevented the Americans from translating possession of the fort into a decisive campaign. [^20]
June 1, 1813 — Shannon Captures Chesapeake
HMS Shannon defeated and captured USS Chesapeake outside Boston. American Captain James Lawrence was mortally wounded.
The encounter checked American confidence in frigate victories and became associated with Lawrence’s famous exhortation, “Don’t give up the ship.” It also showed that the Royal Navy remained a formidable opponent in individual combat. [^21]
June 6 and June 24, 1813 — Stoney Creek and Beaver Dams
At Stoney Creek on June 6, a British counterattack disrupted the American advance. At Beaver Dams on June 24, Indigenous warriors played a central role in defeating another American force.
Laura Secord’s warning became a celebrated part of the Beaver Dams story. The military outcome should also be understood through Indigenous reconnaissance and fighting, rather than attributed to one person alone. [^3][^42]
August 30, 1813 — The Attack on Fort Mims
Red Stick Creek forces attacked Fort Mims in present-day Alabama, killing many defenders and inhabitants.
The attack expanded American intervention in the Creek conflict. The Creek War involved divisions within Muscogee society as well as resistance to American expansion, making it related to the wider war without being reducible to a British-American contest. [^23][^4]
September 10, 1813 — The Battle of Lake Erie
Oliver Hazard Perry’s American squadron defeated and captured the British squadron on Lake Erie.
Control of the lake threatened British supply connections around Detroit and enabled a renewed American advance. The victory’s significance lay in its effect on the land campaign as well as its naval achievement. [^24]
October 5, 1813 — The Battle of the Thames
William Henry Harrison’s army defeated British and Indigenous forces in Upper Canada. Tecumseh was killed.
The battle followed the British retreat made necessary by the loss of Lake Erie. Tecumseh’s death severely damaged his confederacy’s prospects, although Indigenous resistance did not disappear. [^9][^24]
October 26 and November 11, 1813 — American Advances on Montreal Fail
Defenders defeated an American force at Châteauguay on October 26. A second American thrust failed at Crysler’s Farm on November 11.
These outcomes blocked the attempt to capture Montreal. American success in the northwest had not produced equivalent success along the St. Lawrence approaches. [^17][^44]
December 1813 — Destruction on the Niagara Frontier
American troops burned Newark, now Niagara-on-the-Lake. British forces captured Fort Niagara on December 19, and further attacks culminated in the burning of Buffalo on December 30.
The sequence illustrates the destructive cycle of raids and retaliation along the border. Communities experienced the war through displacement and property loss as well as battlefield results. [^3][^41]
1814: Major British Offensives and the Search for Peace
March 27, 1814 — The Battle of Horseshoe Bend
Andrew Jackson’s army, supported by Cherokee and Creek allies, defeated Red Stick forces at Horseshoe Bend on the Tallapoosa River.
The battle was decisive in the Creek War. Its participants show why Indigenous history cannot be described as a single alliance with Britain: Native forces fought on opposing sides for different reasons. [^4]
Spring–Summer 1814 — Napoleon’s Defeat Changes the Strategic Balance
Napoleon’s abdication in April reduced Britain’s immediate military demands in Europe. British reinforcements became available for North American operations.
The United States now faced expanded offensives, although Britain’s improved resources did not guarantee success. Supply, geography, naval support, and American defenses continued to shape results. [^45]
July 3–25, 1814 — The Niagara Campaign
American forces captured Fort Erie on July 3 and won the Battle of Chippawa on July 5. At Lundy’s Lane on July 25, both armies suffered heavy losses in confused, prolonged fighting.
The campaign demonstrated improved American battlefield performance but did not achieve a decisive conquest. After Lundy’s Lane, American troops fell back toward Fort Erie. [^3][^26][^25]
August–September 1814 — The Siege of Fort Erie
British forces besieged the American-held fort. A major assault failed, and an American sortie later damaged the siege works.
The Americans retained the position during the siege, but the campaign did not produce a permanent American foothold in Canada. Fort Erie’s defense should therefore be distinguished from the larger objective of conquering Canadian territory. [^3][^2]
August 9, 1814 — The Treaty of Fort Jackson
Jackson imposed a settlement requiring the Creek Nation to cede nearly 22 million acres.
The land losses affected communities that had opposed the United States and those that had been its allies. The treaty demonstrates that the wider conflict produced substantial territorial consequences for Indigenous peoples, even though Britain and the United States later restored their prewar territorial positions. [^27]
August 1814 — Peace Negotiations Open at Ghent
British and American representatives began formal negotiations in Ghent, in present-day Belgium.
Diplomacy proceeded while military campaigns continued. Negotiators had to assess uncertain battlefield developments, government instructions, and the costs of prolonging the conflict. [^28]
August 24, 1814 — Bladensburg and the Burning of Washington
British forces defeated American defenders at Bladensburg, opening the route to Washington.
British troops entered the capital and burned important public buildings, including the Capitol and the President’s House. The attack was a severe humiliation, but it did not destroy the American government or decide the war. [^29][^30]
September 11, 1814 — Plattsburgh and Lake Champlain
Thomas Macdonough’s American squadron defeated the British squadron on Lake Champlain. George Prevost then withdrew his invading army from the Plattsburgh area.
The outcome disrupted a major British offensive and weakened the case for demanding American territorial concessions at Ghent. Control of inland waterways once again shaped the feasibility of a land campaign. [^31]
September 12–14, 1814 — The Defense of Baltimore
American forces delayed the British advance at North Point on September 12. The bombardment of Fort McHenry on September 13–14 failed to open the harbor to British ships.
Francis Scott Key’s observations inspired the poem later known as The Star-Spangled Banner. The successful defense contrasted sharply with Washington’s recent vulnerability. [^32]
December 15, 1814–January 1815 — The Hartford Convention
New England Federalist delegates met to discuss grievances arising from the war and its economic costs.
The convention rejected secession and proposed constitutional changes. News of peace and victory at New Orleans later damaged the political standing of its participants. The episode demonstrates that American opposition to the war persisted until its closing phase. [^33]
December 24, 1814 — The Treaty of Ghent Is Signed
British and American negotiators signed the peace agreement. It principally restored conquered territory and established procedures for resolving boundary questions.
The treaty did not explicitly settle impressment. Crucially, its signature did not immediately bring peace into effect: ratification and exchange still had to occur. [^28][^1]
1815: New Orleans, Ratification, and Distant Fighting
January 8, 1815 — The Battle of New Orleans
Andrew Jackson’s forces repelled the main British assault near New Orleans. British commander Edward Pakenham was killed.
The victory became central to American memory of the war. It occurred after the treaty had been signed but before peace took effect. Consequently, describing the battle simply as having happened “after the war ended” is misleading. [^34][^1]
February 12, 1815 — British Forces Take Fort Bowyer
After withdrawing from the New Orleans campaign, British forces captured Fort Bowyer on Mobile Point.
The event shows that New Orleans did not instantly end British offensive operations in the Gulf. Hostilities continued while the peace process awaited completion and news circulated. [^35]
February 16–18, 1815 — Peace Takes Effect
The Senate unanimously approved the Treaty of Ghent on February 16. Madison ratified it, and ratifications were exchanged on February 17, bringing the treaty into effect.
Madison proclaimed the treaty on February 18. These distinct steps account for several dates appearing in accounts of the war’s ending. [^1][^36]
February 20, 1815 — Constitution Captures Cyane and Levant
USS Constitution defeated HMS Cyane and HMS Levant near Madeira.
The action occurred after the treaty took effect in Washington. Its place in the chronology reflects the delay in communicating peace to ships operating far away. [^37]
March 23, 1815 — Hornet Captures Penguin
USS Hornet, unaware that the war had ended, captured HMS Penguin near Tristan da Cunha in the South Atlantic.
This encounter makes the practical problem of ending a global naval conflict especially clear. A diplomatic agreement could be effective before commanders at sea learned of it. [^38]
June 30, 1815 — Peacock Engages Nautilus in the Sunda Strait
USS Peacock captured the East India Company brig Nautilus in the Sunda Strait, in present-day Indonesia.
The encounter is commonly identified as the final naval action associated with the War of 1812. It occurred months after peace took effect, illustrating how far the conflict’s maritime operations extended beyond North America. [^39]
The Timeline’s Main Turning Points
| Turning point | Significance |
|---|---|
| Declaration of war, June 1812 | Converted years of disputes into open conflict |
| Detroit and Queenston Heights, 1812 | Undermined expectations of an easy conquest |
| Lake Erie and the Thames, 1813 | Shifted the northwest campaign and damaged Tecumseh’s confederacy |
| Napoleon’s defeat, 1814 | Enabled Britain to reinforce North American operations |
| Plattsburgh and Baltimore, September 1814 | Checked major British offensives |
| Ghent, December 1814–February 1815 | Established and implemented a negotiated peace |
The pattern is one of uneven results across different theaters. The war’s outcome cannot be explained by treating a single battle as decisive everywhere. [^15][^17][^24][^25][^31][^32][^28]

FAQ
Why does a War of 1812 timeline begin in 1807?
The neutral-rights crisis that led to war began in 1807 with the Chesapeake–Leopard affair, the November Orders in Council, and the Embargo Act, so historians commonly treat 1807 as the start of the road to war.
When did the War of 1812 start and end?
The United States declared war on June 18, 1812. The Treaty of Ghent was signed December 24, 1814, and peace took effect when ratifications were exchanged on February 17, 1815.
Was the Battle of New Orleans fought after the war ended?
It was fought on January 8, 1815, after the treaty was signed but before ratification. Under the treaty, peace took effect with the exchange of ratifications on February 17, 1815, so the battle occurred while the war was technically still in force.
Did the war change any borders?
No. The Treaty of Ghent restored the prewar status quo, and maritime grievances were overtaken by Napoleon's defeat in Europe. Indigenous nations, however, lost the diplomatic leverage they had held before 1812.
