grain. They also received considerable amounts of other vital raw materials, including manganese ore, along with the transit of one million tons of soybeans from Manchuria. On January 10, 1941, the countries signed an additional agreement modifying their 1940 commercial agreement, adjusting borders, and resolving other minor disputes. During both the first period of the 1940 agreement (February 11, 1940, to February 11, 1941) and the second (February 11, 1941, until the Pact was broken), Germany received massive quantities of raw materials, including over: 1,600,000 tons of grains 900,000 tons of oil 200,000 tons of cotton 140,000 tons of manganese 200,000 tons of phosphates 20,000 tons of chrome ore 18,000 tons of rubber 100,000 tons of soybeans 500,000 tons of iron ores 300,000 tons of scrap metal and pig iron 2,000 kilograms of platinum In August 1940, Soviet imports comprised over 50% of Germany's total overseas imports, which declined at this time to 20.4 thousands of tons. The trade relations ended when Germany began Operation Barbarossa and invaded the Soviet Union on June 22, 1941. The various items that the USSR had sent to Germany from 1939 to 1941 in significant amount, could be substituted or obtained by increased imports from other countries. Conversely, without Soviet deliveries of these major items, Germany could barely have attacked the Soviet Union, let alone come close to victory, even with more intense rationing.
