Crossing The T
Crossing the ''T'' or capping the ''T'' is a classic naval warfare tactic used from the late 19th to the mid-20th centuries in which a line of warships crosses in front of a line of enemy ships to allow the crossing line to bring all their guns to bear while it receives fire from only the forward guns of the enemy. It became possible to bring all of a ship's main guns to bear only in the late 19th and the early 20th centuries, with the advent of steam-powered battleships with rotating gun turrets, which were able to move faster and turn more quickly than sailing ships, which had fixed guns facing sideways. The tactic became largely obsolete with the introduction of missiles and aircraft as long-range strikes are less dependent on the direction the ships are facing. Tactics When going into battle, ships would assume a battle line formation called "line astern", in which one vessel follows another in one or more parallel lines. This allows each ship to fire over wide arcs wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Powder
Brown powder or prismatic powder, sometimes referred as "cocoa powder" due to its color, was a propellant used in large artillery and ship's guns from the 1870s to the 1890s. While similar to black powder, it was chemically formulated and formed hydraulically into a specific grain shape to provide a slower burn rates with neutral or progressive burning, as opposed to the faster and regressive burn typical of randomly shaped grains of black powder produced by crushing and screening powder formed into sheets in a press box, as was typical for cannon powder previously. Characteristics For pure explosive damage, high burn rates or detonation speeds (and accompanying brisance) are generally preferable, but in guns and especially cannons, slower-burning powder decreases firing stresses. This allows for lighter, longer (and more accurate) barrels with associated decreases in production and maintenance costs. Further modifications of its burning rate were achieved by shaping the powder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pavlos Kountouriotis
Pavlos Kountouriotis ( el, Παύλος Κουντουριώτης; 9 April 1855 – 22 August 1935) was a Greek rear admiral during the Balkan Wars, regent, and the first President of the Second Hellenic Republic. In total he served four times as head of the Greek State, the most times in the history of the seat. Early life Pavlos Kountouriotis was born on the island of Hydra to Theodoros Kountouriotis, Consul and Member of the Greek Parliament and Loukia Negreponte. From his father's side he descended from the Kountouriotis, an Arvanite Hydriot family originally from the village of Kountoura, in the Megarid. Pavlos used Arvanitika frequently as well, and his personal secretary wrote about him that whenever he traveled to Hydra he preferred to use only Arvanitika. He was the grandson of Georgios, a shipowner who like many members of his family, participated in the Greek War of Independence and served as Prime Minister of Greece under King Otto. From his mother's side he was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear Admiral
Rear admiral is a senior naval flag officer rank, equivalent to a major general and air vice marshal and above that of a commodore and captain, but below that of a vice admiral. It is regarded as a two star " admiral" rank. It is often regarded as a two-star rank with a NATO code of OF-7. The term originated in the days of naval sailing squadrons and can trace its origins to the Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear admiral the most junior admiralty of many navies. In most European navies, the equivalent ran ...

Naval Battle Of Elli
The Battle of Elli ( el, Ναυμαχία της Έλλης, tr, İmroz Deniz Muharebesi) or the Battle of the Dardanelles took place near the mouth of the Dardanelles on as part of the First Balkan War between the fleets of the Kingdom of Greece and the Ottoman Empire. It was the largest sea battle of the Balkan Wars. Background Since the start of the war the Hellenic Navy acted aggressively, while the Ottoman navy remained in the Dardanelles. Admiral Kountouriotis landed at Lemnos, while the Greek fleet liberated a series of islands. On 24 October (O.S.), Kountouriotis sent a telegram to the Ottoman admiral: ''"We have captured Tenedos. We await the exit of your fleet. If you need coal, I can supply you."'' On 3 December (OS), the Ottoman fleet left the Dardanelles. Battle The Royal Hellenic Navy, led by Rear Admiral Pavlos Kountouriotis on board of the flagship ''Averof'', defeated the Ottoman Navy, led by Captain Ramiz Bey, just outside the entrance to the Dardanelles ...

Decisive Victory
A decisive victory is a military victory in battle that definitively resolves the objective being fought over, ending one stage of the conflict and beginning another stage. Until a decisive victory is achieved, conflict over the competing objectives will continue. Definitions The phrases "decisive battle" and "decisive victory" have evolved over time, as the methods and scope of wars themselves changed. More modernly, as armies, wars and theaters of operation expanded so that the gestalt (''i.e.'', a result which is greater than the sum total see synergy) of the overall venture was more definitive the phrase "lost its meaning." The meaning is ephemeral, like the difference between “strategy” and "tactics”. In ''Defining and Achieving Decisive Victory'', Colin Gray defined an ''operational'' decisive victory as "a victory which decides the outcome to a campaign, though not necessarily to the war as a whole".Gray, p. 11. The Battle of Midway is often cited as a decis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinovy Rozhestvensky
Zinovy Petrovich Rozhestvensky (russian: Зиновий Петрович Рожественский, tr. ; – January 14, 1909) was an admiral of the Imperial Russian Navy. He was in command of the Second Pacific Squadron in the Battle of Tsushima, during the Russo-Japanese War. Under Admiral Rozhestvensky's command, the Russian navy holds the record of steaming an all-steel, coal-powered battleship fleet over one way to engage an enemy in decisive battle (Battle of Tsushima), selecting , one of four brand-new battleships of the French-designed , as his flagship for the voyage to the Pacific. Early naval career Rozhestvensky was the son of a physician from St Petersburg, and joined the Imperial Russian Navy at the age of 17.Kowner, '' Historical Dictionary of the Russo-Japanese War'', pp. 326–27, 340. He graduated from the Sea Cadet Corps, where he mastered English and French, in 1868, and the Mikhailovsky Artillery Academy in 1873. He initially served with the Baltic Flee ...

Pitched Battle
A pitched battle or set-piece battle is a battle in which opposing forces each anticipate the setting of the battle, and each chooses to commit to it. Either side may have the option to disengage before the battle starts or shortly thereafter. A pitched battle is not a chance encounter such as a meeting engagement, or where one side is forced to fight at a time not of its choosing such as happens in a siege or an ambush. Pitched battles are usually carefully planned, to maximize one's strengths against an opponent's weaknesses, and use a full range of deceptions, feints, and other manoeuvres. They are also planned to take advantage of terrain favourable to one's force. Forces strong in cavalry for example will not select swamp, forest, or mountain terrain for the planned struggle. For example, Carthaginian general Hannibal selected relatively flat ground near the village of Cannae for his great confrontation with the Romans, not the rocky terrain of the high Apennines.

Broadside (naval)
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.Platt (1993) p. 18 History Since a ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amp ...

Wireless
Wireless communication (or just wireless, when the context allows) is the transfer of information between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio ''wireless technology'' include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
