Europe first, with the Far East being a defensive war. After the attack on Pearl Harbor, the British prime minister, Winston Churchill, and the American president, Franklin D. Roosevelt, met at the First Washington Conference. This conference reaffirmed the doctrine of Europe first. At the third Washington Conference in May 1943 alleviating pressure on China was discussed, in particular through the Burma campaign. At the Quebec Conference in August intensifying the war against Japan was decided and South East Asia Command reorganised. The Second Quebec Conference in September 1944 discussed the involvement of the British Navy against the Japanese. Strategic bombing The first strategic bombing raid was carried out by American Flying Fortresses on 2 February 1942 against Kuantan and Kuala Lumpur's airfields. These may have been planes from the 7th Bombardment Group operating out of Java. Missions did not resume against Malaya until 27 October 1944 when B-24 Liberators of No. 159 Squadron RAF flying from Khargpur mined the Penang Strait causing its eventual abandonment by Japanese submarine forces. They laid more mines on 26 November and 23 January 1945. On 11 January 1945 B-29's of the 20th Air Force attacked Penang. A further attack on Penang occurred on 24 February. This was followed by an attack on the marshaling yards in Kuala Lumpar and Alor Star airfield on 10 March. The Royal Selangor museum was hit by bombs on 15 March. The bombs were intended for the Kuala Lumpar marshaling yards. On 28 March mines were dropped in several harbours and the last Malaya mission by the 20th Air Force took place on 29 March when attack was made on a mix of targets. Attacks on the ports ceased around this time as Mountbatten intended to use the ports during the proposed invasion of Malaya. Attacks continued against rail, coastal shipping, and other targets. Action in Malaya and the Straits of Malacca After the defeat by the Japanese, a number of Allied personnel and European civilians retreated into the jungle. Some, including British woman Nona Baker, joined the MPAJA. Others, such as Freddie Spencer Chapman, were Force 136 operatives who sought to begin a sabotage campaign against the occupying Japanese forces. In August 1943 the Allies set up South East Asia Command to oversee the war in South East Asia, including Malaya. As the war progressed further Allied operatives were landed either from submarine or be parachuted in
