40 free Naval History trivia questions with answers — history quiz, new questions added Aug 2026.
Naval history is where geography, engineering and nerve collide: an oared fleet wins an empire in a narrow strait, a single biplane torpedo decides the fate of a 50,000-ton battleship, and an admiral is executed on his own deck to keep the rest of them keen. It is also a history of words, because half the idioms in everyday English came ashore from sailing ships. These 40 questions run from the ancient Mediterranean and the great oared battles of the sixteenth century, through the Armada and the age of sail, to ironclads, dreadnoughts, carriers and the first warship ever sunk by a missile. Along the way they cover the ranks, ship types, traditions and slang of the world's navies, with every answer backed by a one-line explanation that adds something the textbooks skip. Built for pub quizzers, history readers and anyone who has ever wondered why a ship's toilet is called the heads.

Q 04Which Russian battleship's crew mutinied in 1905 after refusing borscht made from maggot-infested meat?

Q 05Cast adrift after the 1789 Bounty mutiny, William Bligh sailed an open boat 3,618 nautical miles to which island?
Timor
Timor held the nearest European outpost, the Dutch settlement of Kupang, and Bligh brought his loyalists there alive on the rations they had in the boat.
Q 06During the 1962 Cuban Missile Crisis, Kennedy avoided the word 'blockade', an act of war, in favour of which term?
Quarantine
Quarantine let the United States stop Soviet ships without the formal implications of a state of war, and the naval cordon stayed in place until 20 November 1962.
Q 07The navy slang 'scuttlebutt', now meaning gossip, originally referred to what on a sailing ship?
A drinking-water cask
A drinking-water cask, a butt 'scuttled' with a hole so water could be drawn, was where sailors gathered and traded rumours, much like today's office water cooler.
Q 08The rank 'admiral' reached English via Anglo-French and Medieval Latin, but ultimately comes from which language?
Arabic
Arabic amīr al-, 'commander of the', gave the world its word for a fleet commander, and a later folk etymology tacked on the Greek word for the sea to make 'prince of the sea'.
Q 09The warship type 'destroyer' was conceived in the late 19th century to defend battle fleets against which small craft?
Torpedo boats
Torpedo boats were the threat, so navies built 'torpedo boat destroyers', a name shortened to plain 'destroyer' by nearly every navy by the First World War.

At the bow
At the bow, the head of the vessel, the crew's toilet sat out over the water, and the name stuck to every toilet afloat.
Q 11A speed of one knot, once measured with a knotted log line and a sand-glass, equals one of which unit per hour?
Nautical mile
Nautical mile per hour is exactly 1.852 km/h; the knots on the log line were spaced 47 feet 3 inches apart so that counting them against a 28-second glass gave the speed directly.
Q 12Which Athenian had the 483 BC Laurion silver strike spent on 200 warships instead of handed to citizens?
Themistocles
Themistocles' fleet won at Salamis three years later, after a message he sent to Xerxes helped lure the Persian navy into the narrow straits.

Trireme
Q 21Driven into the North Sea in 1588, the Spanish Armada sailed home around Scotland and down the coast of which island?

Q 23The 1898 explosion of which US battleship in Havana harbour, killing 268, helped push America into war with Spain?
Trireme crews rowed mostly blind, since 108 of the 170 oarsmen could not see the water, so keeping stroke took great skill and practice.
Q 14What did the Romans call the spiked boarding bridge, named after a bird, that beat Carthage at Mylae in 260 BC?
Corvus
Corvus means 'crow' or 'raven', and the drawbridge let legionaries turn sea fights into land battles; it is mentioned only at Mylae and Ecnomus before vanishing from the sources.

Q 16Lepanto in 1571 was the last major Western battle fought almost entirely between which kind of warship?
Rowing galleys
Rowing galleys and the larger galleasses fought at Lepanto much as oared fleets had for two thousand years; within decades the sailing galleon displaced them and the Age of Sail began.
Q 17Which future novelist, serving aboard the Marquesa, lost the use of his left hand at Lepanto in 1571?

Q 20Which Lord High Admiral held overall command of the English fleet against the Spanish Armada in 1588?
Charles Howard
Charles Howard, Lord Howard of Effingham, was chiefly credited with the victory that saved England from invasion, though popular memory hands the glory to Drake.

Q 26HMS Dreadnought of 1906, which made every earlier battleship obsolete, was the first capital ship driven by what?
Steam turbines
Steam turbines made Dreadnought the fastest battleship afloat when completed, and Fisher had her built in about a year by stockpiling material before her keel was laid.
Q 27Who remarked 'there seems to be something wrong with our bloody ships today' as battlecruisers blew up at Jutland?
