We mark certain days of the year with ‘On This Day’ posts, recalling events associated with them.

Our events are grouped under two calendars. The Gregorian ‘New Style’ (NS) is the worldwide calendar first issued at Rome in 1582. On that calendar, today is September 23. The Julian ‘Old Style’ (OS), also issued at Rome but in 46 BC, was used in Roman Britain and then in England from Anglo-Saxon times until 1752. It is still used today by roughly 100 million Orthodox Christians worldwide. On that calendar, today is September 10.

The Battle of Flamborough Head

When captain Richard Pearson of the Royal Navy surrendered to American revolutionary John Paul Jones, Jones naturally assumed that meant he had won.

Following the Declaration of Independence in 1776, American resentment towards King George III’s dastardly oppression reached such a pitch that they made common cause with that champion of republican liberty, King Louis XVI of France. One mustard-keen revolutionary, John Paul Jones, even buccaneered around Britain’s coastline harassing merchant shipping convoys, until the Royal Navy stepped in.
