Imagine a conflict so unusual that it nearly turned into a full-blown war over a single pig. This is exactly what happened during the Pig War of 1859, a bizarre confrontation between American settlers and the British Empire on San Juan Island. The trouble began when Lyman Cutlar, an American farmer, shot a pig owned by Charles Griffin, a British subject, for rooting through his potatoes.
What started as a simple dispute over livestock quickly escalated as both sides dug in their heels, leading to a tense standoff. The San Juan Islands, located between Vancouver Island and the Washington Territory, became the unlikely scene of this peculiar chapter in history. As the two nations faced off, military forces were called in, but the only casualties were that unfortunate pig and a few potatoes.
This odd conflict showcases how even the smallest incidents can lead to larger tensions. You’ll want to read on to discover how this strange war resolved and what it teaches us about the quirks of history.
Origins of the Conflict
The conflict over the San Juan Islands arose from a combination of border treaties and territorial disagreements. Understanding these origins helps explain how a simple pig could spark a near-war between two powerful nations.
Treaty of Oregon and the Boundary Uncertainty
The Oregon Treaty of 1846 aimed to resolve the Oregon Boundary Dispute between the United States and Great Britain. This treaty established a boundary that extended along the 49th parallel but left some areas, like the San Juan Islands, in question.
As the Boundary Commission worked to clarify the borders, confusion persisted. The San Juan Islands were situated between Vancouver Island (part of what is now British Columbia) and the Washington Territory. This uncertainty created a setting ripe for conflict. Tensions heightened as both countries laid claim to the islands based on their interpretations of the treaty.
San Juan Island: A Disputed Territory
San Juan Island became a focal point in the Northwestern Boundary Dispute. Both the U.S. and Britain believed the island was rightfully theirs. Farmers settled on the island, leading to conflicts over land and resources.
In June 1859, the situation escalated when an American farmer shot a pig that belonged to a British settler. This seemingly minor incident sparked a series of military standoffs. Troops from both sides were deployed, and the island became a symbol of national pride. Each side believed they were protecting their rights, illustrating how territorial disputes can turn into larger conflicts.
The Pig War Escalation

A small incident over a pig quickly led to a tense military standoff between American and British forces in the Pacific Northwest. You’ll find that the actions of a few key individuals propelled the situation into a serious conflict.
The Shooting of the Pig
In June 1859, Lyman Cutlar, an American settler, shot a pig that wandered onto his property. This pig belonged to the British Hudson’s Bay Company. Cutlar’s actions sparked outrage among British officials, who saw this as an act of aggression.
The shooting escalated tensions in the region. American soldiers rallied to Cutlar’s defense, seeing him as a victim. The British responded by sending troops to the area. This pig’s death would kick off a series of confrontations. The incident highlighted the fragile state of relations between the two nations.
Military Standoff Between Britain and America
As news spread, the situation intensified. Both sides began to increase their military presence in the San Juan Islands. British troops, led by Charles Griffin, occupied key locations to assert control. Meanwhile, American forces, under the command of George Pickett, arrived to protect their interests.
The British Navy also played a role. They were ready to back the British troops stationed in the region. The sight of the troops on both sides created a military standoff that made locals anxious. You could feel the tension in the air as neighbors turned into bitter rivals over a seemingly trivial event. This standoff continued for months, revealing how easily a conflict can arise from small disputes.
Peaceful Resolution

The Pig War, although it started over a pig, highlighted the importance of diplomacy and negotiation. Key figures worked together to resolve tensions through careful discussions and international mediation.
Diplomatic Endeavors
President James Buchanan recognized the need for a peaceful solution to avoid conflict. He tapped General Winfield Scott, a seasoned diplomat, to lead negotiations. Scott held discussions with British authorities, including James Douglas, the governor of the colony.
Both sides maintained a military presence but limited their troops to avoid escalation. This compromise showed a commitment to peace. The delegations met repeatedly, emphasizing dialogue over confrontation. They aimed to clarify the British-U.S. border and protect their interests. The Hudson’s Bay Company was also involved, influencing outcomes due to its business interests.
Arbitration by Kaiser Wilhelm I
As tensions eased through negotiation, Kaiser Wilhelm I of Germany stepped in to help. His involvement marked a significant turn towards international arbitration. Through this process, the dispute moved away from potential violence.
The Treaty of Washington in 1872 ultimately resolved the Pig War. It set a clear border between the U.S. and Britain, confirming the peaceful nature of this unusual conflict. Admiral Robert L. Baynes played a role too, ensuring military forces stayed calm during these discussions. This legacy of diplomacy is still celebrated today, reminding us of the power of peaceful resolution.
Legacy of the Pig War

The Pig War left behind a unique legacy that is still recognized today. Key aspects include the establishment of the San Juan Island National Historical Park and the long-lasting effects on U.S.-British relations.
San Juan Island National Historical Park
At the heart of the legacy is the San Juan Island National Historical Park. This park commemorates the site of the standoff between American and British forces. You can explore areas like Bunker Hill and the Sheep Ranch, which were significant during the events.
The park not only helps preserve the history but also offers visitors a chance to learn through guided tours and educational programs. As you walk along the trails, you can appreciate the stunning views of the Haro and Rosario Straits, reminding you of the strategic importance of this location during the conflict.
Impact on U.S.-British Relations
The Pig War is a prime example of how diplomacy can work. The conflict highlighted the need for dialogue rather than armed confrontation.
After this event, U.S.-British relations improved dramatically. This peaceful resolution strengthened mutual respect and cooperation, paving the way for future agreements.
The shared history from this unique incident still plays a role in how the two nations interact today. By learning about this event, you gain insight into the importance of maintaining peace and understanding between countries.
