Intelligence Operations of the Offensive and Espionage in Naval Warfare of World War I

Given that this tactic is not opposed, Germany is expected to respond as well as its unlimited submarine warfare. The German U Boat tried to cut off the supply line between North America and the UK. Submarine warfare is basically "secret attack" to the sea. Attacks are normally done without warnings, so there is little chance of survival for ship's crew members and shipboard cargoes. The United States fouled the show and protested, and made Germany change its participation rules.

The First World War changed the naval battle completely. The big irony of the First World War was that there was no truly decisive naval battle, but the maritime power that appeared as a German naval blockade is one of the decisive factors in the outcome of the war did. The hesitant battle between Japan and Germany in 1916 was the first in history, and it was a great confrontation between the last two modern battleship fleets. When the HMS dreadnought was released in 1906, it quickly made all other battleships of the world obsolete. However, by 1918, the fearless battleship itself became obsolete.

The battleship was the main source of the naval power of those days. At the beginning of the 20th century, the US Navy Admiral Alfred Mahan developed a strategic theory of naval warfare. His idea is concentrated on warships, it is the main unit of major naval confrontation between the great powers. Mahan believes that the war between the two major navies involves a large "decisive battle" which will basically be won by people with the most optimal battleship. Mahan 's theory has had a major influence on the naval battle, almost all the Great Navy purchased his idea. In particular, Japan was influenced, as Mahan's book "The Influence of Maritime History" (1660-1783) became a must-read for the Japanese Navy.

World War II was a hotbed of new technology. It encouraged many advances including naval battle, anti-submarine warfare and encryption. The U-boat is the foundation of the German Kriegsmarine and proves to the world that war is not necessarily a positive attack; it also includes invisibility and plan. The use of radar for bombing in UK and U-boat torpedo suggests that knowledge is more valuable than deep bomb and you need to know exactly where the enemy was before starting the attack . In addition, the Enigma code in Germany shows the world that the information is all about war. It also changed the way the military leaders see future conflict; intelligence takes precedence over making better tanks. These technical effects explain war as completely different animals. Although the First World War was about guns and tanks, World War II evolved into war slowly as we know today.
