On 11 March 1942, during World War II, General Douglas MacArthur and members of his family and staff left the Philippine island of Corregidor and his forces, which were surrounded by the Japanese. They traveled in PT boats through stormy seas patrolled by Japanese warships and reached Mindanao two days later. From there, MacArthur and his party flew to Australia in a pair of Boeing B-17 Flying Fortresses, ultimately arriving in Melbourne by train on 21 March. In Australia, he declared, "I came through, and I shall return". MacArthur's simple declaration, "I came through, and I shall return", was to be the slogan repeated many times during the following three years as he pursued his goal of regaining the Philippines.
