Merchant navy in the context of "Helmsman"

A sailor, seaman, mariner, or seafarer is a person who works aboard a watercraft as part of its crew, and may work in any one of a number of different fields that are related to the operation and maintenance of a ship. While the term sailor has its etymological roots from sailing, that is a time when sailing ships were the main mode of transport at sea, it now refers to the personnel of all watercraft regardless of the type of vessel, boat or ship. It encompasses people who operate ships professionally, be it for a military (navy) or civilian (merchant navy) or for sports or recreation. In a navy, there may be further distinctions: sailor may refer to any member of the navy even if they are based on land, while seaman may refer to a specific enlisted rank. Additionally, fisherman are seen as a distinct type of sailor, that is those engaged in fishing.

Sailors have existed from the earliest periods in history as people used boats for purposes such as maritime transport. Professional sailors normally undertake training or other forms of education to develop their skills. Professional sailors are also governed by regulations, including the STCW Convention.

A prisoner-of-war camp (often abbreviated as POW camp) is a site for the containment of enemy fighters captured as prisoners of war by a belligerent power in time of war.

There are significant differences among POW camps, internment camps, and military prisons. Purpose-built prisoner-of-war camps appeared at Norman Cross in England in 1797 during the French Revolutionary Wars and HM Prison Dartmoor, constructed during the Napoleonic Wars, and they have been in use in all the main conflicts of the last 200 years. The main camps are used for marines, sailors, soldiers, and more recently, airmen of an enemy power who have been captured by a belligerent power during or immediately after an armed conflict. Civilians, such as merchant mariners and war correspondents, have also been imprisoned in some conflicts. Per the 1929 Geneva Convention on Prisoners of War, later superseded by the Third Geneva Convention, such camps have been required to be open to inspection by representatives of a neutral power, but this hasn't always been consistently applied.

The Gato class of submarines were built for the United States Navy and launched in 1941–1943. Named after the lead ship of the class, USS Gato, they were the first mass-produced U.S. submarine class of World War II.

The Gatos, along with the closely related Balao and Tench classes that followed, accounted for most of the Navy's World War II submarines; they destroyed much of the Japanese merchant marine and a large portion of the Imperial Japanese Navy. In some references, the Gatos are combined with their successors, especially the Balao class.

Jean-Baptiste Colbert (French: [ʒɑ̃.ba.tist kɔl.bɛʁ]; 29 August 1619 – 6 September 1683) was a French statesman who served as First Minister of State from 1661 until his death in 1683 under the rule of King Louis XIV. His lasting impact on the organization of the country's politics and markets, known as Colbertism, a doctrine often characterized as a variant of mercantilism, earned him the nickname le Grand Colbert ([lə ɡʁɑ̃ kɔl.bɛʁ]; "the Great Colbert").

A native of Reims, he was appointed Intendant of Finances on 4 May 1661. Colbert took over as Controller-General of Finances, a newly created position, in the aftermath of the arrest of Nicolas Fouquet for embezzlement, an event that led to the abolishment of the office of Superintendent of Finances. He worked to develop the domestic economy by raising tariffs and encouraging major public works projects, as well as to ensure that the French East India Company had access to foreign markets, so that they could always obtain coffee, cotton, dyewoods, fur, pepper, and sugar. He acted to create a favorable balance of trade and increase colonial holdings. As there was slavery in the colonies, in 1682, Colbert commissioned the beginning of a project that would become the Code Noir in 1685, two years after his death. In addition, he founded France's merchant navy (marine marchande), becoming Secretary of State of the Navy in 1669.

The Prussian Navy (German: Preußische Marine), officially the Royal Prussian Navy (German: Königlich Preußische Marine), was the naval force of the Kingdom of Prussia from 1701 to 1867.

The Prussian Navy was created in 1701 from the former Brandenburg Navy upon the dissolution of Brandenburg-Prussia, the personal union of Brandenburg and Prussia under the House of Hohenzollern, after the elevation of Frederick I from Duke of Prussia to King in Prussia. The Prussian Navy fought in several wars but was active mainly as a merchant navy throughout the 18th and 19th centuries, as Prussia's military consistently concentrated on the Prussian Army. The Prussian Navy was dissolved in 1867 when Prussia joined the North German Confederation, and its naval forces were absorbed into the North German Federal Navy.
