World War II: General Douglas MacArthur, at Terowie, South Australia, makes his famous speech regarding the fall of the Philippines, in which he says: "I came out of Bataan and I shall return".

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

Douglas MacArthur was an American general who served as a top commander during World War II and the Korean War, achieving the rank of General of the Army. He served with distinction in World War I; as chief of staff of the United States Army from 1930 to 1935; as Supreme Commander, Southwest Pacific Area, from 1942 to 1945 during WWII; as Supreme Commander for the Allied Powers overseeing the occupation of Japan from 1945 to 1951; and as head of the United Nations Command in the Korean War from 1950 to 1951. MacArthur was nominated for the Medal of Honor three times, and awarded it for his WWII service in the Philippines. He is one of only five people to hold the rank of General of the Army, and the only person to hold the rank of Field Marshal in the Philippine Army.
