The Pig War - OverSimplified

Summary of Main Arguments and Events

• Post-Revolution border confusion (1780s–1812): After the U.S. gained independence, Britain and the U.S. negotiated a western boundary using imperfect maps. The intended border line (from a specific lake toward the Mississippi) proved based on inaccurate geography, creating long-term uncertainty. The War of 1812 was largely a draw, but both sides recognized the border needed fixing again.

• The 49th parallel agreement—and the Oregon deadlock: In response, the U.S. and Britain agreed on a clearer line using the 49th parallel up to the Rockies. Beyond the Rockies, however, both nations claimed the same territory. The dispute escalated into bargaining over control of the Oregon region, driven by:

  • U.S. expansionist pressures, fueled by settlement and “manifest destiny” ideology.
  • British economic interests, especially the Hudson’s Bay Company and fur-trade needs, which pushed Britain to maintain influence in the northwest.

• Joint occupation of Oregon (temporary peace, real rivalry): When neither side could force the other out, they agreed to jointly occupy the disputed region. This allowed both to settle and trade, but the arrangement was expected to fail due to demographic imbalance and competing national goals.

• Breaking the joint occupation and the “channel” treaty ambiguity: Under President Polk, the U.S. increased pressure and threatened escalation. Eventually, the boundary was settled with a line reaching the Strait of Georgia, then moving south through channels to the Pacific. However, the treaty language was vague about which specific channel applied to the islands:

  • Britain argued for the Rosario Strait.
  • The U.S. argued for the Haro Strait.

This ambiguity left the fate of the San Juan Islands unresolved, setting the stage for local conflict.

• Douglas’ strategy: settle first to secure Britain (1853 onward): James Douglas (Hudson’s Bay, later Governor of Vancouver Island) aimed to prevent American encroachment by establishing British claims on San Juan Island, including placing sheep and pigs—even Berkshire pigs—to create visible British presence.

• The “pig war” on the ground (1854–1860s):

  • 1854 customs/tax dispute: An American official tried to negotiate with (and effectively confront) British sheep farmers, leading to a standoff. British officials attempted to assert jurisdiction, while Americans resisted with armed force. A Northern tribe raid helped push the American officer out, but the dispute did not end.
  • Whatcom County seizure (sheep raid): U.S. officials from Whatcom County attempted to seize Griffin’s sheep and auction off breeding rams. Griffin tried to intervene, but American officials drew weapons. Griffin lost 34 breeding rams, prompting diplomatic complaints.
  • Ongoing jurisdictional bickering: Both governments ordered local officials to stand down and formed boundary commissions, but the conflict continued as petty disagreements suggested the treaty ambiguity would keep producing flashpoints.
  • Gold rush influx and escalating personal conflict: After gold discoveries in the Fraser Canyon, more Americans settled on San Juan Island. Lyman Cutler built his cabin in British sheep pastures and fenced poorly, repeatedly clashing with Griffin over pigs damaging crops.
  • Pig shooting incident: Cutler shot one of Griffin’s pigs, demanded Griffin stop interfering, and refused Griffin’s demanded compensation. British officials tried to arrest or punish Cutler under British authority, drawing attention from the U.S. military.

• Harney and Pickett’s brinkmanship (1859):

  • General William S. Harney visited and became enraged, treating the British threat to Cutler as an outrage.
  • Harney’s motivations are framed as potentially including personal glory, political ambition, or expansionist opportunism—though the narrative portrays him as primarily reckless.
  • Harney ordered Captain William H. Pickett to land troops on disputed territory and assert American law on the island—an action designed (whether intentionally or not) to provoke a British response and risk war.

• Royal Navy restraint prevents war:

  • Britain’s Governor Douglas tried to escalate, but the Royal Navy restrained him. A senior naval officer (Admiral Baynes) canceled Douglas’ orders.
  • The crisis was defused as both sides leaned toward restraint. Troops were still fortified and tourists witnessed tension, but direct war never broke out.

• Civil War sidelines the issue; arbitration resolves it later:

  • With the U.S. Civil War beginning in 1861, the San Juan dispute became less urgent than internal conflict.
  • Harney was removed for suspected disloyalty; Pickett later became known for Gettysburg as a Confederate general.
  • After the Civil War, the dispute continued and ultimately went to international arbitration.
  • Germany (Kaiser Wilhelm’s empire) ruled for the United States, awarding the San Juan Islands to the U.S.
  • The last British troops left on November 25, 1872.

• Overall conclusion (the “lesson”): The narrative argues that the “Pig War” was less about pigs themselves and more about border ambiguity, competing national incentives, and local actors escalating misunderstandings. War was avoided largely due to more level-headed military decisions and restraint, with the “only casualty” in the comedic framing being the pig.
