Passage: Golubic completed his primary education in Stolac, before relocating to Sarajevo to attend high school. In 1908, he moved to Belgrade for post-secondary studies, studying law at the University of Belgrade. Some of Golubic's classmates and contemporaries later recounted that Golubic was recruited by the Russian secret police, the Okhrana, in his youth. The historian Vladimir Dedijer later consulted the records of the Hoover Institution in an attempt to verify this claim, to no avail. Golubic did join Young Bosnia (), a multi-ethnic youth organization agitating for the separation of Bosnia and Herzegovina from Austria-Hungary. The organization's membership was around 70 percent Serb, 20 percent Bosnian Muslim and 10 percent Croat. Following the outbreak of the Balkan Wars in November 1912, Golubic joined the volunteer Chetnik detachment of Major Vojislav Tankosic. As part of their training, Tankosic ordered that Golubic and the other volunteers jump into the Sava from a railway bridge, "just to see whether you are going to fulfill all my orders."

Passage: Un'yo was one of the ships dispatched to Kyushu in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yo in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yo was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yo was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.

Passage: At the start of the Second World War before the US entered the war, there were a large number of American volunteers offering their services. No. 71 was formed at RAF Church Fenton on 19 September 1940 with Brewster Buffalos. Appraisal by Royal Air Force acceptance personnel criticised the Brewster Buffalo on numerous points, including lack of armament and pilot armour, poor high-altitude performance, engine overheating, unreliability and cockpit controls, while it was praised for its handling, roomy cockpit and visibility. The aircraft were deemed unsuitable for European conditions and Hawker Hurricanes replaced them from November 1940. The squadron became operational at RAF Kirton-in-Lindsey on 5 February 1941 and moved in April to RAF Martlesham Heath in Suffolk for operations over Europe. During May, it suffered its first loss when Mike Kolendorski was killed during a fighter sweep over the Netherlands. The intensity of operations stepped up with a move into No 11 Group of Fighter Command, being based at RAF North Weald in Essex by June 1941. On 2 July, William J. Hall became the first Eagle Squadron pilot to become a Prisoner of War (POW) when he was shot down during an escort mission. The squadron's first confirmed victory came on 21 July 1941 during a bomber escort mission, when Pilot Officer William R. Dunn destroyed a Messerschmitt Bf 109F over Lille. In August, the Spitfire Mk II replaced 71 Squadron's Hurricanes, before the squadron quickly re-equipped with the latest Spitfire Mk VB. The unit soon established a high reputation, and numerous air kill claims were made in RAF fighter sweeps over the continent during the summer and autumn of 1941. In December, the Squadron was rested back at Martlesham Heath, before a move to Debden in May 1942. When informed of the attack on Pearl Harbor, most of the Eagle Squadron pilots wanted to immediately join the fight against Japan. Representatives from 71 and 121 Squadrons went to the American Embassy in London and offered their services to the United States. The pilots from 71 Squadron decided they wanted to go to Singapore to fight the Japanese and a proposal was put to RAF Fighter Command, but it was turned down. On 29 September 1942 the squadron, together with the other two Eagle squadrons, was transferred to the US Army Air Forces, becoming the 334th Fighter Squadron of the 4th Fighter Group.
