ecame evident that the enemy should not produce it first. Before Roosevelt read Einstein's letter in October, 1939, England and France had declared war on Germany. Despite the major breakthrough, and despite the war in Europe, President Roosevelt merely set up an Advisory Committee on Uranium. Two years passed before Roosevelt ordered intensive research (Yass 22).
             Meanwhile, in England, in 1939, work on atomic fission had gained a slightly better start. A Sunday Express journalist wrote that if a nuclear chain reaction could be produced, "the outpouring of energy would exceed anything ever known in the world. The uses to which it might be put are appalling. A nation at war might be able to wipe out another nation right off the face of the earth". Britain had a group of scientists which was code named the Maud committee which devoted their time to "the use of uranium for a bomb". They now believed they could "make an effective uranium bomb which...would be equivalent, as regards destructive effect, to 1800 tons of TNT., and would release large quantities of radioactive substances which would make places near to where the bomb exploded dangerous to human life for a long period". (Yass 23-25)

             German armies were sweeping everything before them. It became evident that Britain and America must join together in their research of creating a uranium bomb. The plant to extract uranium had been agreed to be to be set up in the U.S.A since England was vulnerable to German Air attack (Yass 26)
             On December 7, 1941 the Japanese attack Pearl Harbor, this attack brought Japan and U.S.A into active war. The war reinforced the president's decision to back the atomic research (Yass 32).
             In January 1942, a British scientific mission boarded the submarine infested Atlantic. They were sailing to America to discuss the atomic fission project with their new Allies. Prime Minister C...
