The War of the Pacific (1879–1884) and the Sino-French War (1883–1885) put the Pacific’s newly made navies to the test after a decade of naval racing. These two wars are rarely compared, despite occurring more or less contemporaneously and employing many of the same technologies. In the War of the Pacific, Chilean victory transformed the Chilean Navy into the “preponderant force in South America.” As a hemispheric matter, the Chilean newly made navy also became a credible danger to the “Old Steam Navy” and soon the US “New Navy’s” nearest pacing threat. Strategic defeat in the Sino-French War masked Chinese tactical successes that would guide the Qing Empire’s self-strengthening efforts in the coming decades. Defeat was not a refutation but rather confirmation of the need to cultivate an effective navy, spurring on the expansion of the Beiyang Fleet until it became the dominant power in Northeast Asia by the early 1890s. In an era of vicious anti-Chinese racism in the United States, the Qing’s possession of a modern navy created debate and cultural anxiety in California.

Confederate naval building during the US Civil War (1861–1865) was a form of “self-strengthening” that had much in common with similar efforts across the Pacific World in the 1860s and 1870s. To overcome structural limitations (a lack of industrial capacity or existing warships), Confederate navy builders relied on foreign acquisitions and local innovations such as the torpedo to compete with the materially superior United States. The US Civil War was, in this sense, a vast practical experiment for small or industrially weak states confronting North Atlantic power. Beginning in the 1860s, the template set by the Confederacy – local adaptation with cheap asymmetric weapons and the overseas acquisition of qualitatively advanced systems – found numerous adopters in Pacific newly made navies. Reciprocally, many industrial producers in Europe were stimulated by demand from the Confederacy to produce novel weapons for Pacific states.

Chapter 2 investigates the global development of the torpedo and its influence on the Imperial Japanese Navy. The Battle of Savo Island, near Guadalcanal, evidenced Japanese proficiency with destroyers, cruisers, and torpedo tactics during World War II.
