A 15th-century royal warship resting off the coast of Sweden as soon as served as a “floating castle” for an intrepid king, in keeping with new underwater investigation that exposed cannons, handguns, crossbows and the vessel’s stern superstructure.
The new finds on the wreck of the Gribshunden — the flagship of King Hans (or John) of Denmark till it sank in 1495 — present the vessel plied the seas as a fearsome ship of conflict armed with dozens of weapons and full of troopers.
It’s thought that the Gribshunden was armed with as much as 90 early cannons, though they had been a lot smaller than the ship-smashing cannons of the late sixteenth century, and that they had been complemented by armored troopers firing handguns and crossbows from the ship’s higher deck, forecastle and sterncastle — the tall superstructures constructed at every finish of the ship.
The 115-foot-long (35 meters) picket ship was one of many first vessels designed to hold artillery. It additionally utilized the brand new “carvel” shipbuilding approach, imported to the Baltic from the Mediterranean, of becoming a member of the planks of the hull edge to edge on a picket body as a substitute of overlapping them in “lapstrakes.”

That meant the Gribshunden might be constructed bigger and stronger than ships with lapstrakes, and so it may carry extra in heavier seas.
“This is kind of a new technology,” Brendan Foley, a maritime archaeologist at Lund University in Sweden who’s main the most recent excavations, instructed Live Science. “It was designed to carry artillery, and King Hans uses the ship in a way that no other king does.”

Royal flagship
From the mid-1480s, Hans often journeyed on the Gribshunden all through his realm, usually surrounded by a giant royal fleet, Foley stated, including that the ship was meant to intimidate the king’s rivals.
The son of the earlier Danish king, Hans dominated Denmark from 1481 and gained the crown of Norway in 1483, however Sweden did not undergo his rule till 1497.
“His realm is Denmark and Norway, and he’s trying to get Sweden to rejoin the Nordic Union,” Foley stated. “So Hans is sailing around on this ship all the time.” (The Nordic Union of Denmark, Norway and Sweden was additionally known as the Kalmar Union, after the city in Sweden the place it was agreed in 1397.)
Hans launched into the Gribshunden (which implies “Griffin dog,” though it initially appears to have been known as “Griffon”) for negotiations at Kalmar in 1495 when the ship mysteriously sank, supposedly after a hearth broke out, at an anchorage simply offshore close to the city of Ronneby.
The king and his retinue had been onshore on the time, however a witness to the disaster (opens in new tab) stated lots of the roughly 150 males onboard had been killed.
Many of the ship’s weapons had been in all probability salvaged quickly after the sinking, Foley stated; the most recent excavations discovered solely 14 gun carriages close to the strict, however many extra had been probably located close to the bow.
A peculiarity of the japanese Baltic Sea is that it is too chilly for infestations of shipworm (which isn’t a worm however a mollusk, Teredo navalis). Because of that, the picket gun carriages are nonetheless intact, though the iron weapons have rusted away, he stated.
But there was no signal of fireplace, so the ship in all probability sank rapidly after being holed under the waterline, probably as a result of its shops of gunpowder had exploded. “It’s one of the first ships carrying gunpowder, so they probably hadn’t worked out standard operating procedures for safety,” Foley stated.

Floating fortress
Local divers rediscovered the wreck of the Gribshunden close to Ronneby within the Seventies, beneath about 33 ft (10 m) of water. It was recognized in 2013, and in 2015, archaeologists recovered a number of artifacts, together with the figurehead of a particular person clutched within the jaws of a canine or dragon, Live Science reported on the time.
Foley led dives to the wreck in August and September, throughout which the staff recovered extra artifacts and captured three-dimensional information for a digital reconstruction.
The wreck is taken into account a proxy for the ships from the Age of Exploration, such as these of Christopher Columbus and Vasco da Gama, which had been constructed at about the identical time however at the moment are misplaced. “Nothing else like this has been found,” Foley stated.
The mixture of weapons and crossbows, as nicely as the remnants of shirts of mail armor that had been additionally discovered, present the transition from earlier weapons to gunpowder, he added.
The bigger ship’s weapons had been mounted on swivels inside their picket carriages and fired projectiles concerning the measurement of golf balls. Meanwhile, the handguns had been quite simple — about 16 inches (40 centimeters) lengthy, with projectiles like musket balls that had been fired by touching a match to a gap within the again. “They were basically like a small cannon,” Foley stated.
Fritz Jürgens, a maritime archaeologist at Kiel University in Germany is not concerned within the research of the Gribshunden, however he is main analysis into a uncommon 400-year-old ship found within the outer stretches of the Trave River within the western Baltic. He famous that the Gribshunden is the oldest carvel-built ship ever discovered within the Baltic and one of many oldest purpose-built warships ever found.
“In the Middle Ages and in the later Hanseatic period [when a trading bloc dominated the Baltic, from the 13th to 17th centuries], they took normal cargo ships and put archers on it,” Jürgens stated. “But the Gribshunden had artillery on the forecastle and sterncastle — it was specifically built for war.”
