July 10, 1940 — The Battle of Britain begins

The Battle of Britain is virtually unique in the annals of wartime history for being one of the few extended campaigns to be fought almost entirely in the air – most other aerial conflicts named battles were single engagements, but the Battle of Britain lasted for nearly five months.

What it was, basically, was the way that air supremacy was decided in the Western European theatre of World War Two. The Axis forces launched an all-out aerial assault on Britain, bombing both civilian and military targets in what became known as The Blitz. Much has been written about the tactical superiority of the British, and there’s certainly truth in that – the Luftwaffe outnumbered the RAF by 2 to 1 in raw numbers, for example. But in the end, the British simply outlasted them. If the Luftwaffe had been better equipped in terms of manpower and aircraft, they might have succeeded in the end, but the RAF was perhaps the pre-eminent air force in the world in 1940, and they demonstrated this here, in their finest hour.

It would be another two years before the momentum of World War Two turned decisively against the Germans, but this was the first major victory of the Allies, and Germany’s inability to conquer Britain at this point would lead Hitler – never that interested in invading the British Isles to begin with – to turn his attentions eastward, leading inexorably to the twin defeats of Stalingrad and El Alamein, and finally, to the unconditional surrender of his nation after he committed suicide in despair.

July 10, 1925 — The Scopes Trial begins in Dayton

John Scopes was arrested for teaching evolution in Dayton, Ohio, because the god-fearing people of Dayton felt that evolution contradicted the sacret teachings of the Bible. The trial was a media circus (by 1925 standards, when they didn’t have a 24 hour news cycle) and ignited a national debate about evolution across America.

It would ultimately result in the conviction of John Scopes for one of the most ridiculous ‘crimes’ ever invented by superstitious idiots.

July 10, 1893 — Daniel Hale Williams performs the second successful pericardium surgery

Daniel Hale Williams was one of the first Afro-American men to achieve prominence as a surgeon. He served as the surgeon-in-chief of Freedman’s Hospital in Washington, D.C. from 1896 to 1898, and also established a teaching college for nurses at the hospital. Other notable achievements include being a charter member of the American College of Surgeons (and the first ever black member) and founding the first non-segregated hospital in America.

But he is best known for performing one of the earliest successful heart surgeries, a pericardium repair on a stabbing victim named James Cornish. Cornish convalesced for 55 days after the operation, but made a full recovery. Cardiac surgery would develop little for another 50 years, until World War Two prompted surgeons to investigate it more closely, and the pioneering work of Williams and others was belatedly recognized.
