Supplies included warships, warplanes and other weapons. It became law on March 11, 1941 and was repealed in September 1945.The Atlantic Charter is a joint declaration signed on August 14, 1941, aboard the USS Augusta, "while sailing somewhere in the Atlantic." The Atlantic Conference was held from August 9 to 12, 1941. President Franklin Delano Roosevelt spoke on behalf of the United States and Winston Churchill on behalf of Great Britain. It states that it has deemed it convenient "to make known certain common principles in the national policy of their respective countries, on which rest their hopes of achieving a better future for the world."
