This Day in History: June 21st

This Day in History: King Charless III of Spain declares war on England, joining France in their assault against their decades-long enemy and helping the Americans greatly in their struggle for independence, spreading Britain's resources thin so that they would finally capitulate, 1779; the U.S. Constitution is ratified, 1788; General Pershing's troops are attacked by the Mexican Army as they try to find and capture the notorious villain Panch Villa, who'd escaped into the mountains of northern Mexico after crossing the U.S. border and slaughtering dozens in New Mexico, 1916; The Byrds hit #1 on the pop charst with a song by Bob Dylan- "Mr. Tambourine Man"- and change the world of music forever, Roger McGuinn's jangly 12-string electric Rickenbacker guitar forming the lush background which launched the folk-rock revolution, 1965
