I. Military Strike
The most important contribution of Britain in the military strike was in the navy, which was built after more than a hundred years of construction of the modern navy and was very strong. The British navy was in full force against Germany and Italy at sea, ensuring the anti-fascist alliance's right to the sea in the Atlantic Ocean and the Mediterranean Sea, and this contribution was very great.
Secondly, the British air force played the role of strategic bombing and front-line air power struggle, mainly night bombing and bombing of Germany's important areas, bombing German armament manufacturing bases and railroads and other transportation arteries, playing an important role in the combat and defense strategy. There was also the Army, which was fourth among the Allies despite its small strength, and in the North African theater it defeated the corps of the Desert Fox Rommel and played a role in holding back Japanese forces in the Burma area.
Two, material support
Britain's support for the Allies in the material aspects of the credit is also very large, in the Soviet Union declared war on Germany, the United Kingdom will be the first to assist the Soviet Union, support a large number of materials and weapons to the Soviet Union, including military ships, a large number of medical equipment and medicines and so on.
Three, transportation and blockade
Because of Britain's strong maritime power and superior geographical location, the Allied escort mission almost entirely fell on Britain's shoulders, providing basic security for the Allied maritime shipping. In addition, the British navy imposed a comprehensive blockade on the German army, mobilizing a large number of destroyers and cruisers to cruise the main routes of the ocean, constituting a tight blockade network.
Fourth, military science and technology research and development
Britain also made breakthroughs in science and technology during World War II. Firstly, they cracked the Enigma code, which was famous for its complexity and difficulty, thus contributing to their access to the Germans' strategic secrets and information. The role of information warfare in modern warfare cannot be underestimated.
In addition, Britain used improved radar in warships and fighters at sea, which played an important role in battles against German submarines and night bombardment of German forces.
Meanwhile, the colonial people were mobilized to aid the war effort "under the aura of God Save the King", and for a time, the helpers of Canada (the Canadian soldiers who fought at the Battle of Normandy) and Australia, the black uncles of Africa, the Indian Arabs with their big heads, and the Arabs with their white turban, all came to pledge their allegiance. There were also elites from fallen countries, such as France, Poland Czechoslovakia and others, who chose to contribute by going into exile in Britain.
