title: Blockade of Germany (1939–1945) text: Blockade of Germany (1939–1945) The Blockade of Germany (1939–1945), also known as the Economic War, was carried out during World War II by the United Kingdom and France in order to restrict the supplies of minerals, metals, food and textiles needed by Nazi Germany – and later Fascist Italy – in order to sustain their war efforts. The economic war consisted mainly of a naval blockade, which formed part of the wider Battle of the Atlantic, and included the preclusive buying of war materials from neutral countries to prevent their sale to the enemy. There were four distinct phases of title: International relations of the Great Powers (1814–1919) text: the new states of Greece and Serbia. In the Treaty of London, signed in 1839, the Great Powers guaranteed the neutrality of Belgium. Germany called it a "scrap of paper" and violated it in 1914 by invasion, whereupon Britain declared war on Germany. The repeal in 1846 of the tariff on food imports, called the Corn Laws, marked a major turning point that made free trade the national policy of Great Britain into the 20th century. Repeal demonstrated the power of "Manchester-school" industrial interests over protectionist agricultural interests. From 1830 to 1865, with a few interruptions, Lord Palmerston set British title: Blockade of Germany text: wartime trade with both sides, Washington government protested vigorously. Britain did not wish to antagonize the U.S. It set up a program to buy American cotton, guaranteeing the price stayed above peacetime levels and mollifying cotton traders. When American ships were stopped with contraband, the British purchased the entire cargo, and released the empty ship. A memorandum to the British War Cabinet on 1 January 1917 stated that very few supplies were reaching Germany or its allies either via the North Sea or other areas such as Austria's Adriatic ports (which had been subject to a French blockade since 1914). title: Operation Stonewall text: Operation Stonewall Operation Stonewall was a World War II operation to intercept blockade runners off the west coast of German-occupied France. It was an effective example of inter-service and international co-operation. From the start of the war, the Allies had maintained a blockade against the import of seaborne goods to Germany. Although rich in many basic industrial materials, Germany, like Britain, could not produce some essentials. These included rubber, tin and tungsten. Until Germany invaded the Soviet Union it evaded the blockade via the Trans-Siberian Railway. Large quantities of materials were shipped by this route. After this was closed, German title: Anglo-Russian War (1807–1812) text: Napoleon could easily cross the Neman River (then the Russian border) and invade Russia. The terms of the treaty obliged Russia to cease her maritime trade with Great Britain. This closure was a part of Napoleon's continuing efforts to establish the Continental System, strengthening economic ties between the different countries in Europe under French domination. Napoleon's objective was to close one of Britain's most important markets and thus force it economically into submission. On 26 October 1807, Tsar Alexander formally declared war on the United Kingdom after the British attack on Copenhagen in September 1807. He did not actively prosecute
