August 9

August 9 is the 222nd day of the year, and the American record for it runs from 1814 to 1974 — a span of 160 years. The entry that anchors it: As a direct result of the Watergate scandal, 1974.

Through the nineteenth century the date gathered the tensions that would define the era. In 1814, American Indian Wars — the Creek sign the Treaty of Fort Jackson, giving up huge parts of Alabama and Georgia. Then, in 1862, American Civil War — Confederate troops counter-attacked and won the Battle of Cedar Mountain, after nearly being driven from the field in the early part of the battle. The same year, Battle of Cedar Mountain — at Cedar Mountain, Virginia, Confederate General Stonewall Jackson narrowly defeats Union forces under General John Pope.

In the decades after the Civil War, the date marked a country remaking itself. In 1877, Nez Perce War — both the Nez Perce and the United States Army suffered numerous casualties at the Battle of the Big Hole, which ended conclusively.

As the country moved into the modern age, the date accumulated new kinds of firsts. In 1942, World War II — in the first major naval engagement of the Guadalcanal campaign, Japan forced the U.S. Navy to withdraw from the Solomon Islands. Two years on, in 1944, the United States Forest Service authorized the use of Smokey Bear as its mascot to replace Bambi. A year later, in 1945, World War II — Nagasaki is devastated when an atomic bomb, Fat Man, is dropped by the United States B-29 Bockscar. Thirty-five thousand people are killed outright, including 23,200–28,200 Japanese war workers, 2,000 Korean forced workers, and 150 Japanese soldiers.

In the postwar decades the date belonged to a nation of enormous reach and unfinished arguments. In 1974, as a direct result of the Watergate scandal, Richard Nixon becomes the first president of the United States to resign from office. Vice President Gerald Ford becomes president.

The date is also a birthday. Among the Americans born on August 9: Elizabeth Schuyler Hamilton (1757), American humanitarian; wife of Alexander Hamilton; Adoniram Judson (1788), American missionary and lexicographer; Jonathan Homer Lane (1819), American astrophysicist who mathematically analyzed the Sun as a gaseous body; William T. G. Morton (1819), American dentist who first used ether as a surgical anaesthetic; and Dorothea Klumpke (1861), American astronomer and academic.

August 9 is also a date of endings. Among the Americans who died on it: Harry Hillman (1945), American runner and coach; Edward Thorndike (1949), American psychologist and academic; Patrick Bouvier Kennedy (1963), American son of John F. Kennedy; and Bill Chase (1974), American trumpet player and bandleader.

The date carries formal observance as well — International Day of the World's Indigenous Peoples (United Nations) and National Day, celebrates the independence of Singapore from Malaysia in 1965.. Read end to end, August 9 is less a list than a cross-section: 8 entries that happen to share a square on the calendar, separated by as much as 160 years. The coincidence is arbitrary; the accumulation is not.
