Differences in interpretation between the United States and Great Britain over the Oregon Treaty and ownership of the San Juan Islands nearly erupted into open hostilities when an American settler, Lyman Cutler, shot and killed a pig that was owned by Charles Griffin, the Hudson's Bay Company agent on San Juan. Both countries sent troops to the islands, but cooler heads eventually prevailed. Although the "Pig War" lasted for a decade, the only casualty was the aforementioned pig. This bibliography is limited to published materials about the Pig War itself, including both primary materials and secondary sources, as well as some Internet sources and unpublished dissertations.
