December 29

December 29 is the 364th day of the year, and the American record for it runs from 1778 to 1959 — a span of 181 years. The entry that anchors it: Sioux Wars, 1890.

The revolutionary generation left its own mark on the date. In 1778, American Revolutionary War — British forces under the command of Lieutenant Colonel Archibald Campbell defeat American forces under Major General Robert Howe and capture the port city of Savannah, Georgia.

The antebellum decades brought the date closer to the country’s central argument. In 1835, the Treaty of New Echota is signed, ceding all the lands of the Cherokee east of the Mississippi River to the United States. Ten years on, in 1845, the Republic of Texas was annexed by the United States, becoming the 28th state to be admitted to the Union. Then, in 1862, American Civil War — the Battle of Chickasaw Bayou ends in a Union defeat as forces under General William T. Sherman are repulsed with heavy losses by Confederate troops under General John C. Pemberton.

Reconstruction and the years that followed added their own entries. In 1876, a railway bridge collapsed over the Ashtabula River in Ohio, killing 92 people and injuring 64 others on a Lake Shore and Michigan Southern Railway train. Then, in 1890, Sioux Wars — the United States Army killed 250 to 300 Lakota men, women and children at the Wounded Knee Massacre, beginning the Ghost Dance War. The same year, Wounded Knee Massacre — on Pine Ridge Indian Reservation, 300 Lakota are killed by the United States 7th Cavalry Regiment.

After 1945 the date reflects a country operating at global scale. In 1959, American physicist Richard Feynman gave a speech entitled "There's Plenty of Room at the Bottom" at Caltech, anticipating the field of nanotechnology.

The date is also a birthday. Among the Americans born on December 29: Charles Goodyear (1800), American chemist and engineer; John Langdon Sibley (1804), American librarian; Andrew Johnson (1808), American general and politician, 17th President of the United States; George Washington Baines (1809), American politician, journalist and educator; and Albert Pike (1809), American author, poet, orator, editor, lawyer, jurist, and general.

December 29 is also a date of endings. Among the Americans who died on it: Spotted Elk (1890), American tribal leader; William James Linton (1897), English-American painter, author, and activist; Charles Yerkes (1905), American financier; and Abby Leach (1918), American educator.

The date carries formal observance as well — The fourth day of Kwanzaa (United States). The record for December 29 runs 181 years deep across 8 entries. Read in sequence, the date stops being a coincidence and starts being a through-line.
