The Battle

History & Significance

German U-boat operations in the Gulf of Mexico and Atlantic approaches in 1918 represented the only hostile military action in US coastal waters during WWI. These attacks influenced the post-war Navy expansion program.

Historical context

The frontier period of the American West (roughly 1865–1900) was defined by cattle drives, mining booms, railroad construction, and the violent suppression of Indigenous resistance. Texas longhorn cattle drives north along the Chisholm Trail to railheads in Kansas brought beef to eastern markets from the 1860s through the 1880s. Mining rushes to the Black Hills (1874), Colorado (1858–1859), and the Comstock Lode in Nevada attracted tens of thousands of prospectors and boom towns that rose and collapsed within years. The range wars between cattle ranchers and homesteaders, vigilante justice, and the careers of figures like Wyatt Earp, Jesse James, and Billy the Kid became mythologized in dime novels and later in film. The Dawes Act (1887) and the opening of Oklahoma Territory to homesteading (1889) completed the legal dismantling of Indigenous land tenure in the West. By 1890 the US Census declared the frontier effectively closed, and the era of open-range cattle drives ended with the introduction of barbed wire fencing across the plains.
