See it on the Battles & Wars map →What happened
Galleons, from the 1530s, were tall sailing ships with heavy cannon low in the hull, firing through lidded gunports. They fought and carried treasure for Spain, Portugal and England. In the Anglo-Dutch Wars of the 1650s, fleets adopted the line of battle: ships in single file firing broadsides. Only ships strong enough to stand in that line, with 60 to over 100 guns, were 'ships of the line'. HMS Victory (1765), with 104 guns, took about 6,000 trees to build.
Why it matters
For two centuries these were among the most complex machines and costliest state projects in the world, letting Britain, France, Spain and the Dutch project power worldwide. Steam and iron ended them by the 1860s.
Think of it like
Each first-rate was its era's megaproject: years of construction, thousands of tonnes of timber, and a crew the size of a small town.
How we know
Surviving ships such as HMS Victory in Portsmouth and Sweden's Vasa (sank 1628, raised 1961); wrecks like the Mary Rose; navy shipbuilding records; logbooks; and battle reports.
Still debated
How rigid the line of battle really was, and when bold admirals like Nelson were right to break it, is long argued by naval historians.
Connections (4)
▸Horatio Nelson commanded fleets of Galleons and ships of the lineWell documented
The connection
Nelson spent his career in ships of the line, the big two- or three-decked sailing warships of 64 to over 100 guns. He commanded the 64-gun Agamemnon, flew his flag in the 74-gun Vanguard at the Nile and in the 104-gun Victory at Trafalgar. He mastered the type's tactics, then broke the rigid line-of-battle rules.
When and how
Royal Navy, 1771–1805; from his early commands to HMS Victory, launched in 1765, at Trafalgar.
How we know
Ships' logs and Admiralty records; HMS Victory survives in dry dock at Portsmouth, still a commissioned Royal Navy ship.
Debates and open questions
Breaking the enemy line was not new: Rodney did it at the Saintes in 1782. How original Nelson's tactics were is debated.
▸Galleons and ships of the line fought on both sides of the Defeat of the Spanish ArmadaWell documented
The connection
In 1588 Spain sent about 130 ships, including galleons, armed merchantmen and supply hulks, to escort an invasion army from Flanders. England's faster, lower galleons kept their distance and fired repeatedly, while Spanish ships were built to close and board. Fire ships broke the Spanish formation at Calais, and storms finished it.
When and how
English Channel and North Sea, July–August 1588; the Duke of Medina Sidonia against Lord Howard and Francis Drake.
How we know
Fleet lists, captains' reports and wrecks off Ireland, such as La Trinidad Valencera, show the ships and guns.
Debates and open questions
How much English gunfire actually damaged the Spanish fleet is debated; most losses came from storms and wrecks off Scotland and Ireland.
▸Galleons and ships of the line fought in line of battle at Battle of TrafalgarWell documented
The connection
At Trafalgar 27 British ships of the line met 33 French and Spanish. Instead of fighting in parallel lines, Nelson cut through the enemy line in two columns, so British ships, with faster gunnery, fought at close range. Twenty-two allied ships were taken or destroyed; no British ship was lost.
When and how
Off Cape Trafalgar, southwest Spain, October 21, 1805; Nelson in HMS Victory against Admiral Villeneuve.
How we know
Ships' logs, captains' reports and Nelson's own memorandum of October 1805 describing the plan.
Debates and open questions
Whether Nelson's attack was a radical new tactic or a bold use of ideas already tried at the Saintes (1782) and Camperdown (1797) is debated.
▸Ironclad warships (Gloire, USS Monitor) made obsolete the wooden Galleons and ships of the lineWell documented
The connection
Ships of the line ruled sea warfare from the 1650s. But shells could set wooden hulls on fire, and iron armor stopped the shot these ships fired. Once France and Britain launched Gloire and Warrior in 1859–60, construction of wooden battleships stopped; within a decade the old three-deckers were laid up, sold or made training ships.
When and how
France and Britain, 1859–1860s; the last wooden ships of the line were completed in the early 1860s.
How we know
Navy construction records show the switch; HMS Victory and HMS Warrior both survive in Portsmouth's historic dockyard.
Debates and open questions
Historians debate whether shells, armor or steam engines did most to end the wooden warship, since all three arrived within about twenty years.
