  On 16 December 1944, Germany made a last attempt to split the Allies on the Western Front by using most of its remaining reserves to launch a massive counter-offensive in the Ardennes and along the French-German border, hoping to encircle large portions of Western Allied troops and prompt a political settlement after capturing their primary supply port at Antwerp. By 16 January 1945, this offensive had been repulsed with no strategic objectives fulfilled. In Italy, the Western Allies remained stalemated at the German defensive line. In mid-January 1945, the Red Army attacked in Poland, pushing from the Vistula to the Oder river in Germany, and overran East Prussia. On 4 February Soviet, British, and U.S. leaders met for the Yalta Conference. They agreed on the occupation of post-war Germany, and on when the Soviet Union would join the war against Japan.
  
  In February, the Soviets entered Silesia and Pomerania, while the Western Allies entered western Germany and closed to the Rhine river. By March, the Western Allies crossed the Rhine north and south of the Ruhr, encircling the German Army Group B. In early March, in an attempt to protect its last oil reserves in Hungary and retake Budapest, Germany launched its last major offensive against Soviet troops near Lake Balaton. Within two weeks, the offensive had been repulsed, the Soviets advanced to Vienna, and captured the city. In early April, Soviet troops captured Königsberg, while the Western Allies finally pushed forward in Italy and swept across western Germany capturing Hamburg and Nuremberg. American and Soviet forces met at the Elbe river on 25 April, leaving unoccupied pockets in southern Germany and around Berlin.
  
  Soviet troops stormed and captured Berlin in late April. In Italy, German forces surrendered on 29 April, while the Italian Social Republic capitulated two days later. On 30 April, the Reichstag was captured, signalling the military defeat of Nazi Germany.
  
  Major changes in leadership occurred on both sides during this period. On 12 April, President Roosevelt died and was succeeded by his vice president, Harry S. Truman. Benito Mussolini was killed by Italian partisans on 28 April. On 30 April, Hitler committed suicide in his headquarters, and was succeeded by Grand Admiral Karl Dönitz (as President of the Reich) and Joseph Goebbels (as Chancellor of the Reich); Goebbels also committed suicide on the following day and was replaced by Lutz Graf Schwerin von Krosigk, in what would later be known as the Flensburg Government. Total and unconditional surrender in Europe was signed on 7 and 8 May, to be effective by the end of 8 May. German Army Group Centre resisted in Prague until 11 May. On 23 May all remaining members of the German government were arrested by the Allied Forces in Flensburg, while on 5 June all German political and military institutions were transferred under the control of the Allies through the Berlin Declaration.
  
  In the Pacific theatre, American forces accompanied by the forces of the Philippine Commonwealth advanced in the Philippines, clearing Leyte by the end of April 1945. They landed on Luzon in January 1945 and recaptured Manila in March. Fighting continued on Luzon, Mindanao, and other islands of the Philippines until the end of the war. Meanwhile, the United States Army Air Forces launched a massive firebombing campaign of strategic cities in Japan in an effort to destroy Japanese war industry and civilian morale. A devastating bombing raid on Tokyo of 9–10 March was the deadliest conventional bombing raid in history.
  
  In May 1945, Australian troops landed in Borneo, overrunning the oilfields there. British, American, and Chinese forces defeated the Japanese in northern Burma in March, and the British pushed on to reach Rangoon by 3 May. Chinese forces started a counterattack in the Battle of West Hunan that occurred between 6 April and 7 June 1945. American naval and amphibious forces also moved towards Japan, taking Iwo Jima by March, and Okinawa by the end of June. At the same time, a naval blockade by submarines was strangling Japan's economy and drastically reducing its ability to supply overseas forces.
  
  On 11 July, Allied leaders met in Potsdam, Germany. They confirmed earlier agreements about Germany, and the American, British and Chinese governments reiterated the demand for unconditional surrender of Japan, specifically stating that " the alternative for Japan is prompt and utter destruction ". During this conference, the United Kingdom held its general election, and Clement Attlee replaced Churchill as Prime Minister.
  
  The call for unconditional surrender was rejected by the Japanese government, which believed it would be capable of negotiating for more favourable surrender terms. In early August, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. Between the two bombings, the Soviets, pursuant to the Yalta agreement, declared war on Japan, invaded Japanese-held Manchuria and quickly defeated the Kwantung Army, which was the largest Japanese fighting force. These two events persuaded previously adamant Imperial Army leaders to accept surrender terms. The Red Army also captured the southern part of Sakhalin Island and the Kuril Islands. On the night of 9–10 August 1945, Emperor Hirohito announced his decision to accept the terms demanded by the Allies in the Potsdam Declaration. On 15 August, the Emperor communicated this decision to the Japanese people through a speech broadcast on the radio (Gyokuon-hōsō, literally "broadcast in the Emperor's voice"). On 15 August 1945, Japan surrendered, with the surrender documents finally signed at Tokyo Bay on the deck of the American battleship USS Missouri on 2 September 1945, ending the war.
