The Battle of Pianosa, 1519: Andrea Doria and War at Sea as a Private Business (EVM0064)

Boarding off Pianosa, 25 April 1519

A Genoese squadron catches the flotilla of Kaid Ali, a Barbary corsair based at Tunis, in the Tyrrhenian Sea within sight of Elba. Two galleys go in first, and the fight turns into exactly what the plate shows: five enemy vessels closing on Andrea Doria’s own galley, three on his consort, decks locked together, and the whole thing decided by men crossing from one hull to another.

What saved it was an attack from behind

With the boarding action going badly, Filippino Doria came up from the rear with two more galleys at the moment when it looked lost. Kaid Ali was taken alive. The victory broke one of the rising corsair bases of the Barbary coast and established Andrea Doria as the foremost galley commander in the Mediterranean — a reputation that turned out to be a tradeable asset.

The part that is usually left out: the fleet was his

Those galleys belonged to Andrea Doria personally. He built, manned and maintained them, and then contracted himself and his squadron out to whichever state would pay — Genoa, the Papacy, France, and from 1528 the Emperor Charles V. This was not unusual. The naval power of the sixteenth-century Mediterranean was substantially in private hands, hired by the campaign under written contract, exactly as Italian condottieri had sold land armies for two centuries.

The fleet that defended Christian shipping was privately owned, and its loyalty had a price and a due date.

And in 1528 the invoice went unpaid

Doria was in French service when Francis I fell behind on payments and manoeuvred against Genoese commercial interests. He took his squadron over to Charles V — with immediate strategic consequences for the war in Italy, and for Genoa, which he restored as an independent republic under Spanish protection. One man’s contract decided the naval balance of the western Mediterranean, because there was no state fleet large enough to replace him.

Why the boarding is the whole picture

A galley action was not a gunnery duel. The heavy guns fired forward, once, at close range, and then the ships met. Everything that mattered happened in the few minutes when two decks were joined — which is why a galley carried a large fighting complement on top of its rowers, and why the plate is composed as a crowd rather than as a manoeuvre.

The rowers, who are the reason the arithmetic works

⚠️ It is worth saying plainly what a galley ran on. Its motive power was men — convicts, prisoners of war and slaves on both the Christian and the Muslim side — and the men taken at Pianosa were a resource as much as a defeat. The same category of person was rowing the other flotilla. The naval war of the sixteenth-century Mediterranean was fought, on both sides, by people who had not chosen to be there. The private-enterprise logic of this period turns up again in EVM0060, where a British gunner belongs to a civil department rather than to an army.
