"On June 15, 1859, exactly thirteen years after the adoption of the Oregon Treaty, the ambiguity led to direct conflict. Lyman Cutlar, an American farmer who had moved onto the island claiming rights to live there under the Donation Land Claim Act, found a large black pig rooting in his garden. He had found the pig eating his tubers. This was not the first occurrence. Cutlar was so upset that he took aim and shot the pig, killing it. It turned out that the pig was owned by an Irishman, Charles Griffin, who was employed by the Hudson's Bay Company to run the sheep ranch. He also owned several pigs that he allowed to roam freely. The two had lived in peace until this incident. Cutlar offered $10 to Griffin to compensate for the pig, but Griffin was unsatisfied with this offer and demanded $100. Following this reply, Cutlar believed he should not have to pay for the pig because the pig had been trespassing on his land. (A possibly apocryphal story claims Cutlar said to Griffin, "It was eating my potatoes." Griffin replied, "It is up to you to keep your potatoes out of my pig.") When British authorities threatened to arrest Cutlar, American settlers called for military protection. This small dispute between farmers added to an already strained relationship between Canada and the US, By August 10, 1859, 461 Americans with 14 cannon under Colonel Silas Casey were opposed by five British warships mounting 70 guns and carrying 2,140 men." https://en.m.wikipedia.org/wiki/Pig_War_(1859)
