Portuguese galleon São João Baptista
São João Baptista, nicknamed "Botafogo", was a Portuguese galleon built in the 16th century, around 1530, considered one of the biggest and most powerful Portuguese warships.
History
The exact date of its construction is unknown; the oldest known references to the vessel mention the "great galleon São João" sailing in a convoy to Guinea, under the command of Duarte Coelho in 1532, but it could be simply a galleon with the same name.Friar Manuel Homem says that this galleon mounted 366 bronze pieces of artillery, including the ones that garrisoned the high castles of stern and bow. The pamphlet attributed to Doctor Jorge Coelho, which appears to have been written during the reign of King John III of Portugal, says that the galleon was built in Portas do Mar in Lisbon, by Master João Galego, father of Pedro Galego, being laid down on 29 August 1533 and 230 workers were employed in its construction, of which 30 worked on it daily, and launched on 24 June 1534. It also says that its keel had the length and a half of the largest carrack of India, and that it had five gun decks, with the same number of 366 guns.
The oldest known estimates regarding its armament range from 80 to 200 guns, including a large chase gun. It was among the earliest recorded vessels to have gun ports with lids, which were opened to expose the cannon as a show of firepower.
In 1533, King John III pondered sending the great vessel to Goa, the capital of Portuguese India, so as to reinforce the firepower of Portuguese fleets that operated in the Indian Ocean against the galleys, dhows, and junks of Asia, but Duarte Coelho advised him against it.
Capture of Tunis
São João Baptista most famously distinguished itself during the Conquest of Tunis (1535), when it bombarded La Goletta fortress.Besides São João Baptista itself, a further 20 war caravels and 2 carracks, bearing a total of 1,500 men made up the Portuguese expedition. The entire fleet carried 598 guns in total, most of them small caliber. Its captain was António de Saldanha, with Infante Luís, Duke of Beja, brother of John III, and brother-in-law of Charles V being in overall command of the expeditionary corps, the galleon being his flagship.
Emperor Charles V visited the galleon personally, and marveled at its construction quality and armaments, while Andrea Doria also inspected the vessel on the occasion and regarded it favorably for its strength and orderliness.
