Captain Brooks claims a mid-Pacific atoll for the United States; he calls it the Middlebrook Islands

The sealing ship Gambia raised the flag under the Guano Islands Act, planting a U.S. claim a third of the way between Honolulu and Tokyo.

Nine years before the transcontinental railroad, American ships were already looking past California toward Asia. On July 5, 1859, Captain N.C. Brooks of the sealing ship Gambia sighted a tiny atoll roughly a third of the way from Honolulu to Tokyo, Japan and claimed it for the United States under the Guano Islands Act of 1856. He called it the "Middlebrook Islands." No one ever mined a scrap of guano there, but the claim would eventually contribute to Midway becoming the first Pacific island formally annexed by the United States, though that annexation did not occur until Captain Reynolds's visit in 1867.

The American Throughline

Brooks's guano claim looked like a footnote for decades, but the atoll's location, equidistant between North America and Asia, made it indispensable once technology caught up: a Pacific telegraph relay station in 1903, then a naval air station. That same geography turned it into the site of the June 1942 battle that broke Japan's carrier fleet and turned the Pacific war.

QWhy does Midway run on a completely different clock than the rest of Hawaii?

Every other island in the Hawaiian archipelago runs on Hawaii-Aleutian Standard Time, but Midway keeps Samoa Time (UTC-11:00), an hour behind its neighbors. Midway is also one of only three islands in the Hawaiian Islands chain that isn't part of the state of Hawaii; its exclusion traces back to the 1867 annexation making it a separate U.S. possession, a status later confirmed when the Hawaii Admission Act of 1959 explicitly excluded Midway from the new state's jurisdiction. So a bird flying from Honolulu to Midway crosses a state line and a time zone without ever leaving American soil.

QWhat were the three landmasses Brooks and Reynolds actually claimed?

Midway Atoll is really three islands arranged in a rough circle around a central lagoon: Sand Island, Eastern Island, and Spit Island. Only Sand Island has ever been inhabited or developed, and it still has an airstrip today. Eastern Island has no facilities and no residents. Spit Island is barely more than a narrow reef poking above the waterline. The entire atoll totals about 2.4 square miles, a footprint smaller than many American shopping districts, yet it produced one of the most consequential place-names in Pacific War history.

QHow old is the volcanic rock beneath Midway's lagoon?

The atoll formed roughly 28 million years ago from an extinct shield volcano that has long since eroded and subsided beneath the Pacific, leaving only the coral rim visible today. In Hawaiian, the atoll carries two older names: Kuaihelani, meaning "the backbone of heaven," and Pihemanu, "the loud din of birds," a nod to the enormous seabird colonies that still nest there. Brooks's 1859 claim was, geologically speaking, staking a flag on the tip of an ancient underwater mountain.
