Ship of the line in the context of "Armed merchantman"

Mir Jafar (Full Name:Syed Mir Muhammad Jafar Ali Khan Bahadaur) (c. 1691 – 5 February 1765), was a commander-in-chief or military general who reigned as the first dependent Nawab of Bengal of the British East India Company. His reign has been considered by many historians as the start of the expansion of British control of the Indian subcontinent in Indian history and a key step in the eventual British domination of vast areas of pre-partition India. He is notoriously known for his betrayal of Nawab Siraj-ud-Daulah (Nawab of Bengal, Bihar and Orissa) in the Battle of Plassey.

Mir Jafar served as the commander of the Bengali army under Siraj ud-Daulah, but betrayed him during the Battle of Plassey and ascended to the masnad after the British victory in 1757. Mir Jafar received military support from the East India Company until 1760, when he failed to satisfy various British demands. In 1758, Robert Clive discovered that Jafar had made a treaty with the Dutch East India Company at Chinsurah through his agent Khoja Wajid. Dutch ships of the line were also seen in the River Hooghly. Jafar's dispute with the British eventually led to the Battle of Chinsurah. British company official Henry Vansittart proposed that since Jafar was unable to cope with the difficulties, Mir Qasim, Jafar's son-in-law, should act as Deputy Subahdar. In October 1760, the company forced him to abdicate in favor of Qasim. However, the East India Company eventually overthrew Qasim as well due to disputes over trade policies. Jafar was restored as the Nawab in 1763 with the support of the company. Mir Qasim, however, refused to accept this and went to war against the company. Jafar ruled until his death on 5 February 1765 and lies buried at the Jafarganj Cemetery in Murshidabad.

The United States Congress authorized the original six frigates of the United States Navy with the Naval Act of 1794 on March 27, 1794, at a total cost of $688,888.82 (equivalent to $18.6 million in 2024). These ships were built during the formative years of the United States Navy, on the recommendation of designer Joshua Humphreys for a fleet of frigates powerful enough to engage any frigates of the French or British navies, yet fast enough to evade any ship of the line.

One of these original six, the USS Constitution, is still in commission and is the world's oldest commissioned naval warship still afloat.

The French Navy (French: Marine nationale, pronounced [maʁin nɑsjɔnal], lit. 'National Navy'), informally La Royale (French pronunciation: [la ʁwajal], lit. 'The Royal [One]'), is the maritime arm of the French Armed Forces and one of the four military service branches of France. It is among the largest and most powerful naval forces in the world recognised as being a blue-water navy. The French Navy is capable of operating globally and conducting expeditionary missions, maintaining a significant overseas presence. The French Navy is one of eight naval forces currently operating fixed-wing aircraft carriers, with its flagship Charles de Gaulle being the only nuclear-powered aircraft carrier outside the United States Navy, and one of two non-American vessels to use catapults to launch aircraft.

Founded in the 17th century, the French Navy is one of the oldest navies still in continuous service, with precursors dating back to the Middle Ages. It has taken part in key events in French history, including the Napoleonic Wars and both world wars, and played a critical role in establishing and securing the French colonial empire for over 400 years. The French Navy pioneered several innovations in naval technology, including the first steam-powered ship of the line, first seagoing ironclad warship, first mechanically propelled submarine, first steel-hulled warship, and first armoured cruiser.

The line of battle or the battle line is a tactic in naval warfare in which a fleet of ships (known as ships of the line) forms a line end to end. The first example of its use as a tactic is disputed—it has been variously claimed for dates ranging from 1502 to 1652. Line-of-battle tactics were in widespread use by 1675.

Compared with prior naval tactics, in which two opposing ships closed on one another for individual combat, the line of battle has the advantage that each ship in the line can fire its broadside without fear of hitting a friendly ship. This means that in a given period, the fleet can fire more shots. Another advantage is that a relative movement of the line in relation to some part of the enemy fleet allows for a systematic concentration of fire on that part. The other fleet can avoid this by manoeuvring in a line itself, with a result typical for sea battles since 1675: two fleets sail alongside one another (or on the opposite tack).

A warship or combatant ship is a naval ship that is used for naval warfare. Usually they belong to the navy branch of the armed forces of a nation, though they have also been operated by individuals, cooperatives and corporations. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew.

In wartime, the distinction between warships and merchant ships is often blurred. Until the 17th century it was common for merchant ships to be pressed into naval service, and not unusual for more than half of a fleet to be composed of merchant ships—there was not a large difference in construction, unlike the difference between a heavily armoured battleship and an ocean liner. Until the threat of piracy subsided in the 19th century, it was normal practice to arm larger merchant ships such as galleons. Warships have also often been used as troop carriers or supply ships, such as by the French Navy in the 18th century or the Imperial Japanese Navy during the Second World War. In war since the early 20th century, merchant ships were often armed and used as auxiliary warships, such as the Q-ships of the First World War and the armed merchant cruisers of the Second World War.

An ironclad was a steam-propelled warship protected by steel or iron armor constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859, narrowly preempting the British Royal Navy. However, Britain built the first completely iron-hulled warships.

Ironclads were first used in warfare in 1862 during the American Civil War, when they operated against wooden ships, and against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War.

A broadside is the side of a ship, or more specifically the battery of cannon on one side of a warship or their coordinated fire in naval warfare, or a measurement of a warship's maximum simultaneous firepower which can be delivered upon a single target (because this concentration is usually obtained by firing a broadside). From the 16th century until the early decades of the steamship, vessels had rows of guns set in each side of the hull. Firing all guns on one side of the ship became known as a "broadside". The cannon of 18th-century men of war were accurate only at short range, and their penetrating power mediocre, which meant that the thick hulls of wooden ships could only be pierced at short ranges. These wooden ships sailed closer and closer towards each other until cannon fire would be effective. Each tried to be the first to fire a broadside, often giving one party a decisive headstart in the battle when it crippled the other ship.

The Battle of Vigo Bay, also known as the Battle of Rande (Galician: Batalla de Rande; Spanish: Batalla de Rande), was a naval engagement fought on 23 October 1702 during the opening years of the War of the Spanish Succession. The engagement followed an Anglo-Dutch attempt to capture the Spanish port of Cádiz in September in an effort to secure a naval base in the Iberian Peninsula. From this station the Allies had hoped to conduct operations in the western Mediterranean Sea, particularly against the French at Toulon.

The amphibious assault, however, had proved a disaster, but as Admiral George Rooke retreated home in early October, he received news that the Spanish treasure fleet from America, laden with silver and merchandise, had entered Vigo Bay in northern Spain. Philips van Almonde convinced Rooke to attack the treasure ships, despite the lateness of the year and the fact that the vessels were protected by French ships-of-the-line.

The capital ships of a navy are its most important warships; they are generally the larger ships when compared to other warships in their respective fleet. A capital ship is generally a leading or a primary ship in a naval fleet.
