Rommel was one of the most talented generals in the German army. On the French battlefield, his tanks were once called "the devil's army" because of their rapid advance and fierce offensive. He is also a man who knows neither hunger nor weariness, who is equally agile in thought and action, and who is always on the front line. Because he always shared the joys and sorrows with the soldiers and shared all the hardships and dangers, he was also a very popular figure. The Allies called the legendary German general the "Desert Fox.". On March 31, Rommel commanded four German divisions to attack from the east of Aragai. On April 15, the British were forced to retreat to the border area between Egypt and Libya. Subsequently, the two sides launched a seesaw battle in Egypt for nearly a year. Narrator: In September 1940, the German General Staff reported that the Führer was preparing to get involved in the Italian adventure in Africa. A puzzled Rommel privately assured his friend Kurt Hayes: "Hitler himself has just told me that he will never provide Africa with a single person or a single coin!" The Trail of the Fox by David Owen 20． American involvement After the outbreak of the war in Europe, the American government tried to avoid being involved in the war in accordance with its usual tradition. On September 5, 1939, President Roosevelt signed the Declaration of Neutrality of the United States, which also banned the export of munitions and war materials to belligerent countries. However, it is also based on tradition that there is widespread sympathy for Britain and France in American society. Opinion polls in September 1939 showed that 80% of Americans wanted Britain, France and Poland to win and Germany to lose. In early November, the United States Congress amended the Neutrality Act to lift the arms embargo. The principle of "cash and carry" was approved, and the belligerent countries could purchase military materials from the United States, but they had to pay cash and transport them by themselves. In the summer of 1940, when the news of the French defeat came, the Americans were greatly dismayed, and the U.S. government felt that German expansion would threaten American interests. The U.S. government began to turn the industrial economy into a wartime track,ultrasonic extraction cbd, and constantly expanded and strengthened its national defense forces. The neutrality policy of the United States also took a turn in favor of the Allies. On June 14, the day of the fall of Paris, President Roosevelt signed legislation increasing the number of U.S. Navy ships by 11%. On June 15, he ordered the scientific research that eventually produced the atomic bomb. On 30 June, the United States drew up a huge armament work plan, stipulating that it should manufacture and equip 1 million army weapons, reserve weapons for 2 million troops, establish a military production capacity that can arm 4 million troops,sonicator homogenizer, and the aviation industry should be able to supply 18,000 aircraft a year. On July 3, Congress appropriated $5 billion for the purpose. On July 19, Roosevelt signed the Two-Ocean Fleet Act, which plans to expand the navy by 70% in the next five years, in an effort to have a navy that can defeat Germany and Italy in the Atlantic and Japan in the Pacific at the same time. The US Air Force also plans to expand to 2.1 million people and increase the number of armed aircraft to 100,000. These armament plans clearly reveal that the United States is prepared for a long war. On September 16, the United States Congress passed the Compulsory Military Service and Military Training Act, which was the first time that the United States implemented compulsory military service in peacetime. By June 30, 1941, the U.S. Army had rapidly increased from 269000 a year ago to 1.462 million, with 26 infantry divisions, 2 cavalry divisions, 1 motorized division, ultrasonic cutting machine ,ultrasonic emulsifying machine, 4 tank divisions and 215 functional regiments. It is equipped with 8,639 aircraft, 963 tanks, 7,599 artillery pieces, 4,852 mortars, 15971 machine guns of various types, and 92973 vehicles; the Air Force has grown from 43,000 to 167,000, and has been organized into 45 combat air groups and six transport groups; The Navy grew from 189,000 to 339,000, with 15 battleships, six aircraft carriers, one escort carrier, 18 heavy cruisers, 19 light cruisers, 168 fleet destroyers, 113 submarines and more than 400 auxiliary ships and vessels. The rapid expansion and high level of technology and equipment of the US military have made all the countries involved in the war ashamed and coveted. While strengthening its own combat readiness, the United States also began to regard Britain as the "first line of defense" against the German, Italian and Japanese fascist groups. President Roosevelt kept giving "fireside chats" and heart-to-heart talks with the American people over the radio waves, telling them that the victory of the Axis powers would seriously harm American interests: American enterprises would lose markets in Europe and Asia, fascist expansion would directly threaten American freedom, democracy and way of life, and therefore, it was time to help the avant-garde Britain of the United States. Churchill was also very good at taking advantage of Roosevelt's pro-British attitude. He wrote to Roosevelt from time to time, and his tone became more and more cordial. In September 1940, Churchill wrote urgently: "According to the current loss rate, we will not be able to support for a long time." Later, with Roosevelt's support, the US and British governments reached an agreement: the United States gave Britain 50 old fleet destroyers, 20 torpedo boats, 150 aircraft, and 250,000 rifles in order to lease eight British bases in the Caribbean Sea. Roosevelt believed that having these bases was like putting a "steel ring that Germany could not break" on the United States. At the same time, the United States also took the opportunity to squeeze British power out of the Western Hemisphere. Section 18: Breaking the "Myth of the US Dollar" April 20, 2005 In the second half of 1940, with the rapid growth of British arms orders, Britain's foreign exchange and gold reserves were gradually exhausted. The "cash and carry" principle was a problem: Britain had ships to carry it, but no cash to pay for it. On December 8, Churchill sent "the most important letter of his entire career," an urgent appeal to Roosevelt for help. Roosevelt immediately expressed his understanding and pointed out to the American people at a press conference on December 17 that "Britain's victory in self-defense is the best direct defense for the United States" and that "the superstition of the dollar" should be broken and war materials should be leased to the British. On March 11, 1941, the United States Congress passed the historic Lend-Lease Act, authorizing the President to sell,ultrasonic spray nozzle, transfer, exchange and lease weapons and strategic materials to countries that are beneficial to the security of the United States, regardless of their ability to pay. fycgsonic.com
