It does say so in the article.
I imagine it might be difficult to put the bullet where you want it otherwise.

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 which 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.
Military escalation
Brigadier-General William S. Harney, commanding the Dept. of Oregon, initially dispatched 66 American soldiers of the 9th Infantry under the command of Captain George Pickett to San Juan Island with orders to prevent the British from landing. Concerned that a squatter population of Americans would begin to occupy San Juan Island if the Americans were not kept in check, the British sent three warships under the command of Captain Geoffrey Hornby to counter the Americans. Pickett was famously quoted as saying defiantly, "We'll make a Bunker Hill of it," placing him in the national limelight. The situation continued to escalate. 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. During this time, no shots were fired.
The governor of the Colony of Vancouver Island, James Douglas, ordered British Rear Admiral Robert L. Baynes to land marines on San Juan Island and engage the American soldiers under the command of Brigadier-General Harney. (Harney's forces had occupied the island since July 27, 1859.) Baynes refused, deciding that "two great nations in a war over a squabble about a pig" was foolish. Local commanding officers on both sides had been given essentially the same orders: defend yourselves, but absolutely do not fire the first shot. For several days, the British and U.S. soldiers exchanged insults, each side attempting to goad the other into firing the first shot, but discipline held on both sides, and thus no shots were fired.
