Context paragraphs:
Japanese occupation of Hong Kong: The Imperial Japanese occupation of Hong Kong (香港日治時期) began when the Governor of Hong Kong, Sir Mark Young, surrendered the British Crown colony of Hong Kong to Imperial Japan on 25 December 1941.  The surrender occurred after 18 days of fierce fighting against the overwhelming Japanese forces that had invaded the territory.  The occupation lasted for three years and eight months until Japan surrendered at the end of Second World War.  The length of this period (三年零八個月) later became a metonym of the occupation.

Nettō! Gekitō! Quiz-tō!!: Nettō!  Gekitō!  Quiz-tō!!  (熱闘!  激闘!  クイズ島!!  , Hot Fighting!  Fierce Fighting!  Quiz Island!! )  is a quiz arcade game that was released by Namco in 1993 only in Japan; it runs on the company's NA-2 hardware, and is the tenth title from them which allows scores that do not end in "0".  It is also the second game from the company for which a knowledge of all three Japanese writing systems (Hiragana, Katakana, and Kanji) is essential if players wish to succeed with it (the first was "Bakuretsu Quiz Ma-Q Dai Bōken", which had been released in the previous year - but it only allowed two players to play simultaneously).  The players must help four characters called Kufū (工夫), Hana No Sei (花の精), Koseibutsugakusha (古生物学者) and Nōfu (農夫) regain control of an island, by answering multiple-choice questions (like what Scott and Stanley had to do to regain the crown's lost jewels in "Bakuretsu Quiz"); each of the characters starts out in one of the four corners of the island and conquers a square once they have cleared its stage.  They can then decide which square they want to move to next, by pressing one of the Answer Buttons - and if one character moves onto another one's conquered square it will invoke a special type of quiz, in which the conquered square's owner will set the trespasser eight questions (and there shall be a keyword that is common to all eight answers).  If the trespasser answers all eight questions correctly he (or she, in the case of Hana No Sei) will take possession of the square; but if they should get one wrong, the owner will send the trespasser back to their last conquered square.  If there are less than four players, four characters named Chisogin Bob (地底人ボブ), Ringu (リング), Makoto (まこと) and Pochi (ポチ) shall fill in for the missing ones (until they have been defeated) - and most of the stages have four-answer questions, but there are also ones that have picture questions, ones with only two and three answers, ones of four different genres, ones that players shall receive twice the usual time bonus for answering, and ones that will decrease the required number of correct answers by one before they start.  Once all thirty-six squares on the island have been conquered by the last surviving player, the final boss, Chitei Daimao (地底大魔王) shall emerge from underneath the island for the first time in 300 years (meaning that the last time he did it would have been in 1693); he has three different phases, and each time the last surviving player answers all eight questions in one phase correctly, he will change colour (in the case of the third phase, he will explode, much like all the animal opponents in the game do when defeated).  The player will then be treated to the unique ending sequence of his or her character - however, unlike in "Exvania", all four of them have good endings.

Battle of Centuripe: The Battle of Centuripe was fought from 2 to 4 August 1943, as part of the Allied invasion of Sicily during World War II.  The 78th "Battleaxe" Division, of the British Eighth Army, was engaged in fierce fighting around the town of Centuripe in the central portion of Sicily in the hill country between the Rivers Dittaìno and Salso.  The battle focused around Centuripe which the German Wehrmacht had heavily fortified the hill town set on a very high rocky pinnacle and approached by only one steep and twisty road.  Centuripe itself was the key to the whole Adrano position and the capture of Adrano would in turn force the Germans to withdraw to new positions.  The British troops captured the town after heavy fighting and as a result caused the Germans to start contemplating abandoning Sicily altogether.

Battle of Jarama: The Battle of Jarama (February 6–27, 1937) was an attempt by General Francisco Franco's Nationalists to dislodge the Republican lines along the river Jarama, just east of Madrid, during the Spanish Civil War.  Elite Spanish Legionnaires and Moroccan "Regulares" from the Army of Africa forced back the Republican Army of the Centre, including the International Brigades, but after days of fierce fighting no breakthrough was achieved.  Republican counterattacks along the captured ground likewise failed, resulting in heavy casualties to both sides.

Thomas Sumter: Thomas Sumter (August 14, 1734 – June 1, 1832) was a soldier in the Colony of Virginia militia; a brigadier general in the South Carolina militia during the American War of Independence, a planter, and a politician.  After the United States gained independence, he was elected to the United States House of Representatives and to the United States Senate, where he served from 1801 to 1810, when he retired.  Sumter was nicknamed the "Carolina Gamecock," for his fierce fighting style against British soldiers after they burned down his house during the Revolution.

Battle of Ürümqi (1933): The First Battle of Ürümqi was a conflict in the spring of 1933 between the armies of the Xinjiang provincial government and the Chinese Muslim 36th Division (National Revolutionary Army) of the national government of China.  The Chinese government secretly urged Gen. Ma Zhongying to attack Jin Shuren while at the same time assuring Jin that he was recognized as the legitimate Governor.  Fierce fighting broke out at the gates of the city, and one of the Chinese commanders torched a street where the Muslims troops had managed to break through at the West Gate, killing everyone in the vicinity, including refugees.  The Muslims were then forced to retreat into the range of machine gun fire, which killed many of them.

Battle of Tskhinvali: The Battle of Tskhinvali (Georgian: ცხინვალის ბრძოლა ; Russian: Бои за Цхинвали ) was a fight for the city of Tskhinvali, capital of South Ossetia.  It was the only major battle in the Russo-Georgian War.  Georgian ground troops entered the city on early 8 August 2008, after an artillery assault.  Their advance was stopped by South Ossetian militia and members of the Russian peacekeeping force stationed in the city.  Russian combat troops began entering South Ossetia through the Roki tunnel.  After being initially forced to withdraw, the Georgian troops made several attempts to retake the city.  Due to the difficult logistics of the terrain, the arrival of Russian reinforcements was slow.  After fierce fighting, Georgian troops were finally forced to withdraw from the city on the evening of 10 August.  On 11 August, all Georgian troops left South Ossetia.  Parts of Tskhinvali were devastated in the three-day fighting.

Alikianos: Alikianos (Greek: Αλικιανός ) is the head village of the Mousouroi municipal unit in Chania regional unit, Crete located approximately 12.5 kilometers southwest of Chania.  Alikianos is best known outside the island for the fierce fighting which took place there during the 1941 Battle of Crete, during which the 8th Greek Regiment (Provisional) aided by the local population, helped cover the retreat of the 10th New Zealand Division, to which it was attached.  In retribution, the German paratroopers executed many civilians from Alikianos and the nearby villages.

It overlooks the road between Tel-Aviv and Jerusalem, 25 kilometers west of Jerusalem and 14 kilometers southeast of Ramla.  It was the site of fierce fighting during the 1948 war.  During the 1948–1967 period, it was occupied by Jordan at the edge of a no man's land between the armistice lines known as the Latrun salient.  In the 1967 war, it was captured by Israel along with the whole salient and the West Bank, and remains under Israeli occupation.
