Primarily a military meeting between the USA and Britain, the conference resulted in a declaration of the doctrine of "unconditional surrender".
The conference saw the Combined Chiefs of Staff join American President Franklin D. Roosevelt and British Prime Minister Winston Churchill to discuss the future strategy for fighting the Second World War. Representing the Free French forces, Generals Charles de Gaulle, and Henri Giraud were also in attendance. Roosevelt’s attendance at the conference marked the first time a President had left American soil during wartime. Meanwhile the Soviet leader Joseph Stalin declined his invitation as he felt his presence was needed at home during the ongoing Battle of Stalingrad.
The conference saw the leaders agree to invade Sicily after the North African Campaign, as a way to pull Axis forces away from mainland Europe and weaken the German defence ahead of a later Allied invasion of France. In return, Churchill agreed to send more troops to the Pacific in order to help the American forces continue their fight against the Japanese. Meanwhile, they agreed to launch combined bombing missions against Germany and to destroy German U-boats in the Atlantic.
Details of the conference were kept from the public until the participants left Casablanca. However, a number of journalists were invited for a press conference on the 24th January where vague details of the discussions were announced by Roosevelt. He did, however, announce his demand for the unconditional surrender of the Axis powers – an approach that had been discussed at the conference, but was not fully embraced by Churchill.
