June 12

June 12 is the 164th day of the year, and the American record for it runs from 1775 to 2018 — a span of 243 years. The entry that anchors it: American Civil War, 1864.

The colonial record reaches this date first. In 1775, American War of Independence — British general Thomas Gage declares martial law in Massachusetts. The British offer a pardon to all colonists who lay down their arms. There would be only two exceptions to the amnesty: Samuel Adams and John Hancock, if captured, were to be hanged.

By the middle of the nineteenth century the date carries heavier freight. In 1864, American Civil War, Overland Campaign: Battle of Cold Harbor: Ulysses S. Grant gives the Confederate forces under Robert E. Lee a victory when he pulls his Union troops from their position at Cold Harbor, Virginia and moves south.

In the postwar nineteenth century the date tracks a nation rebuilding. In 1898, Philippine Declaration of Independence — General Emilio Aguinaldo declares the Philippines' independence from Spain. A year later, in 1899, New Richmond tornado — the ninth deadliest tornado in U.S. history kills 117 people and injures around 200.

The postwar entries show a nation both expanding and contesting itself. In 1967, the United States Supreme Court in Loving v. Virginia declares all U.S. state laws that prohibit interracial marriage to be unconstitutional. Then, in 1987, Cold War — at the Brandenburg Gate, U.S. President Ronald Reagan publicly challenges Mikhail Gorbachev to tear down the Berlin Wall.

Closer to the present, the date is still accumulating. In 2016, Forty-nine civilians are killed and 58 others injured in an attack on a gay nightclub in Orlando, Florida, United States; the gunman, Omar Mateen, is killed in a gunfight with police. Two years on, in 2018, United States President Donald Trump and Kim Jong-un of North Korea hold the first meeting between leaders of their two countries in Singapore.

The date is also a birthday. Among the Americans born on June 12: Patrick Gass (1771), American sergeant (Lewis and Clark Expedition) and author; Robert Clark (1777), American physician and politician; Samuel Cooper (1798), American general; Samuel Wright Mardis (1800), American politician; and John A. Roebling (1806), German-American engineer, designed the Brooklyn Bridge.

June 12 is also a date of endings. Among the Americans who died on it: Philip Livingston (1778), American merchant and politician; Lucretia Peabody Hale (1900), American journalist and author; Teresa Carreño (1917), Venezuelan-American singer-songwriter, pianist, and conductor; and Jimmy Dorsey (1957), American saxophonist, composer, and bandleader (The Dorsey Brothers and The California Ramblers).

The date carries formal observance as well — Loving Day (United States) and Women Veterans Recognition Day (United States). June 12 carries 8 entries spread across 243 years. None of the people in them knew they were sharing a date; that is a pattern only visible looking back.
