On this day in history:

On September 23, 1338, the first naval battle of the hundred years' war, the Battle of Arnemuiden, occurred. Big whoop, but - it was the first known naval battle to involve gunpowder based artillery. Five, count 'em, five, English cogs were set upon by a huge French fleet. One English ship had 3 cannons and a hand gun, but they were merchant ships. Insofar as they were set upon by a sizable French fleet, we must assume that those were the equivalent of warships. After an entire day's combat, the French forced the English to surrender, captured the English ships and their cargo, and slaughtered all of the surviving crewmen. Total English fatalities were 1,000, to a mere 900 for the French. The war continued for well over 100 years, nonetheless.
.

1779brought us a more famous naval battle, though not necessarily by name, Battle of Flamborough Head. This ws the famous ship to ship duel between the Bonhomme Richard and the Serapis in which John Paul Jones declared that he had not yet begun to fight and which he eventually won. Cannons were de rigeur by this time, though two of Jones' 18 pounders exploded killing those nearby, causing Jones to abandon the use of an entire battery of 6 of them. This was a classic pyrrhic victory in many ways, but Jones won the battle and fame sufficient that in his later years he was hired by none other than Catherine the Great as a rear admiral in the Black Sea.
