5 Military Metrics — Staff Scoring System
While the British side could maintain continuous resupply from the Esquimalt naval base, the U.S. side could only conduct limited overland transit from Fort Bellingham; however, settler population support partially closed this gap.
Rear Admiral Baynes' decision that 'I will not involve two great nations in a war over a pig' marked the triumph of high-level staff judgment; Harney's aggressive stance had to be restrained by Washington.
Pickett's rapid landing on the island with 66 soldiers created a fait accompli; the delayed response of British ships generated a time-space advantage in favor of the U.S.
Both sides accurately assessed enemy force levels, but the British side correctly read the political intelligence that Washington would not risk war.
Royal Navy's 2,140 marines and 167 cannons against the U.S. 461 soldiers created an effective force ratio of approximately 5:1; therefore, the real multiplier for the U.S. was the will for diplomatic resolution.
Strategic Gains & Victory Analysis
Long-term strategic gains assessment after battle
Victor's Strategic Gains
- ›The United States established full sovereignty over the San Juan Islands following the 1872 Kaiser Wilhelm I arbitration.
- ›The western boundary of Washington Territory was decisively drawn in favor of the U.S., gaining strategic depth in the Pacific Northwest.
Defeated Party's Losses
- ›Britain was forced to withdraw from critical archipelagos adjacent to Vancouver Island, retracting its Pacific sovereignty line.
- ›Despite Royal Navy's overwhelming superiority, the political concession collapsed Hudson's Bay Company's economic influence in the region.

Asian Art of War
Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
A pure example of Sun Tzu's principle 'the supreme victory is winning without fighting'; Baynes' refusal to issue the fire order delivered a true victory to both sides.
Intelligence Asymmetry
Despite Governor Douglas' aggressive insistence, Baynes correctly read London's political will; Harney, however, created escalation without Washington's approval, failing on the intelligence-decision axis.
Heaven and Earth
The narrow coastal strip and foggy conditions of the islands hindered the use of naval artillery, while the forested interior allowed ground forces to establish fortifications.
Western War Doctrines
Delaying/Holding Action
Maneuver & Interior Lines
Pickett's initial landing was rapid and decisive, but during the subsequent 12-year process, both sides shifted to static garrison positioning; no maneuver warfare occurred.
Psychological Warfare & Morale
Clausewitz's concept of 'friction' worked in favor of the command staff's sanity in this incident; soldiers from both sides paradoxically transformed the morale multiplier into cooperation by celebrating Christmas together.
Firepower & Shock Effect
HMS Tribune's 31 guns offered overwhelming firepower potential; however, neither side actually employed the shock element, and fire superiority became merely a tool of deterrence.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
Britain's center of gravity was naval artillery, while America's was settler population and continental support; however, the real Schwerpunkt was the diplomatic channel, and both capitals correctly identified this.
Deception & Intelligence
No classic military deception occurred; instead, both sides employed bluff-counter-bluff diplomacy. Pickett's aggressive stance with limited forces carried elements of psychological deception.
Asymmetric Flexibility
Rear Admiral Baynes' refusal to execute Governor Douglas' attack order by stepping outside the chain of command is a rare example of asymmetric staff flexibility; this initiative prevented the war.
Section I
Staff Analysis
The ambiguous border language of the 1846 Oregon Treaty left the sovereignty of the San Juan Islands unresolved. Britain claimed the islands by accepting Rosario Strait as the border instead of Haro Strait. Against the U.S. force of 461 soldiers, Britain held an overwhelming 5:1 military superiority with 2,140 marines and 5 warships. However, Rear Admiral Baynes' decision to avoid escalation and General Winfield Scott's diplomatic intervention prevented the tactical superiority from translating into strategic gain.
Section II
Strategic Critique
The British Command, despite holding overwhelming military superiority, lacked political audacity, causing Sun Tzu's 'winning without fighting' principle to work against Britain. On the U.S. side, Brigadier General Harney's aggressive unilateral decision had to be reined in by Washington, testing the chain of command discipline. Although Captain Pickett's 'fait accompli' maneuver was a tactical brilliance, the truly decisive factor was the 1872 German arbitration. The fraternal relations between the two garrisons during the 12-year joint occupation period stand as a rare example of professionalism in military history.
