The most intense date on the American history calendar

Thus began another chapter in the history of asymmetrical warfare in North America.

As per Wikipedia, here's a selected list of the things that have happened on this date in American history:

1775 – American Revolutionary War: The war begins with an American victory in Concord during the battles of Lexington and Concord.

1861 – American Civil War: Baltimore riot of 1861: A pro-Secession mob in Baltimore attacks United States Army troops marching through the city.

1892 – Charles Duryea claims to have driven the first automobile in the United States, in Springfield, Massachusetts.

1927 – Mae West is sentenced to ten days in jail for obscenity for her play "Sex."

1971 – Charles Manson is sentenced to death (later commuted to life imprisonment) for conspiracy in the Tate–LaBianca murders.

1985 – Two hundred ATF and FBI agents lay siege to the compound of the white supremacist survivalist group The Covenant, The Sword, and the Arm of the Lord in Arkansas; the CSA surrenders two days later.

1987 – The Simpsons first appear as a series of shorts on "The Tracey Ullman Show," first starting with "Good Night." 

1993 – The 51-day FBI siege of the Branch Davidian building outside Waco, Texas, USA, ends when a fire breaks out. Eighty-one people die.

1995 – Oklahoma City bombing: The Alfred P. Murrah Federal Building in Oklahoma City, USA, is bombed, killing 168.

2011 – Fidel Castro resigns as First Secretary of the Communist Party of Cuba after holding the title since July 1961. 

2013 – Boston Marathon bombing suspect Tamerlan Tsarnaev is killed in a shootout with police. His brother Dzhokhar is later captured hiding in a boat inside a backyard in the suburb of Watertown.

One can, with the right kind of Hunter Thompson-esque eyes, trace the path of the American gestalt through history in this list, yes? 

Also, some notable April 19 birthdays: Eliot Ness, Suge Knight, Jayne Mansfield, Ashley Judd and James Franco. 

Charles Darwin, who's having a moment these days as people attempt to naturally de-select themselves by not quarantining, died on this date in 1882. Aaron Hernandez, who references back to both Charles Manson and the Battles of Lexington and Concord, took his own life on this date in 2017. We also, in loving memory, note that Levon Helm passed on this date eight years ago.
