Context paragraphs:
Eadnoth the Younger: Eadnoth the Younger or Eadnoth I was a medieval monk and prelate, successively Abbot of Ramsey and Bishop of Dorchester.  From a prominent family of priests in the Fens, he was related to Oswald, Bishop of Worcester, Archbishop of York and founder of Ramsey Abbey.  Following in the footsteps of his illustrious kinsman, he initially became a monk at Worcester.  He is found at Ramsey supervising construction works in the 980s, and around 992 actually became Abbot of Ramsey.  As abbot, he founded two daughter houses in what is now Cambridgeshire, namely, a monastery at St Ives and a nunnery at Chatteris.  At some point between 1007 and 1009, he became Bishop of Dorchester, a see that encompassed much of the eastern Danelaw.  He died at the Battle of Assandun in 1016, fighting Cnut the Great.

Caupolicán the Younger: Caupolicán the Younger according to Juan Ignacio Molina was the son of the toqui Caupolicán.  He was made toqui following the capture and execution of his father in 1558.  He continued the first Mapuche rising against the Spanish conquistadors in 1558 and commaned the Mapuche army in constructing a "pukara" at Quiapo to block García Hurtado de Mendoza from rebuilding a fort in Arauco completing the chain of forts for suppression of their rebellion.  In the Battle of Quiapo the Mapuche suffered a terrible defeat and there Caupolicán the younger died.  His successor as toqui was Illangulién.

Battle of Byeokjegwan: The Battle of Byeokjegwan (or Pyŏkje) (Chinese: 碧蹄館大戰; "Bì tí guǎn dàzhàn") was a battle fought on January 27, 1593 (January 26 according to the Japanese calendar of the time), between the armies of the Ming Dynasty led by Li Rusong, and the Japanese forces under Tachibana Muneshige, Ukita Hideie, and Kobayakawa Takakage.  As part of the Japanese Invasion of Korea (Imjin War), it was the first field battle fought during the war between the two sides.

Battle of Assandun: The Battle of Assandun (or Essendune) was fought between Danish and English armies on 18 October 1016.  There is disagreement whether Assandun may be Ashdon near Saffron Walden in north Essex or, as long supposed, Ashingdon near Rochford in southeast Essex, England.  It ended in victory for the Danes, led by Canute the Great, who triumphed over the English army led by King Edmund Ironside.  The battle was the conclusion to the Danish reconquest of England.

Ulrich Fugger the Younger: Ulrich Fugger the Younger (1490 - 1525; "von der Lilie") was a German merchant and businessman from the Fugger family.  Active in Augsburg, he was the second-eldest son of Ulrich Fugger the Elder and Veronika Lauginger.  In 1516 he married Veronika Gassner.  He was a successful businessman and his uncle Jakob Fugger planned that he would be his successor at the head of the family firm, though Ulrich the Younger died before this could happen - Ulrich's will passed over his younger brother Hieronymus as unsuitable for the succession (their elder brother Hans had died in 1515), so Jakob's eventual successor was another nephew, Anton Fugger.

Battle of Bloody Bay: The Battle of Bloody Bay, or Blàr Bàgh na Fala in Scottish Gaelic, was a naval battle fought near Tobermory, Scotland.  It was fought on the coast of Mull two miles north of Tobermory, between John MacDonald of Islay, the Lord of the Isles and chief of Clan Donald; and his son, Angus Og Macdonald.  The precise date of the battle varies in sources, from 1480 to 1483.  After the battle, in which Angus Og Macdonald emerged victorious, the latter seized power from his father, and held it for a decade.  However, Angus's victory would prove pyrrhic.  Many clansmen had died in the battle and nearly half the clan's fleet had been sunk, as a result of which the power of the Lords of the Isles was henceforth greatly diminished.  Angus, last of the independent Lords of the Isles, would himself be murdered ten years later, in 1490.

Battle of Glendale (Skye): The Battle of Glendale was a battle fought on the Inner Hebridean island of Skye, between the MacDonalds of Sleat and the MacDonalds of Clanranald, against the MacLeods of Harris and Dunvegan and the MacLeods of Lewis.  According to MacLeod tradition preserved in the early 19th century, the battle was fought in about the year 1490; yet it has been recently suggested that the battle more likely took place sometime after 1513.  MacLeod tradition records that the battle was the 'most tremendous battle' that the clan ever fought—although the clan was victorious, it never fully recovered from its severe losses.  MacLeod tradition relates how the MacDonalds originally had the upper hand during the conflict, but when the MacLeod's sacred Fairy Flag was unfurled the MacLeods gained heart and won the battle.

Battle of Pima Butte: The Battle of Pima Butte, or the Battle of Maricopa Wells, was fought on September 1, 1857 at Pima Butte, Arizona near Maricopa Wells in the Sierra Estrella.  Yuma, Mohave, Apache and Yavapai warriors attacked a Maricopa village named Secate in one of the largest battles in Arizona's history.  It was also the last major battle fought by the Yumas and the last major battle fought solely between native Americans in North America.

Battle of Tsushima: The Battle of Tsushima (Russian: Цусимское сражение , "Tsusimskoye srazheniye"), also known as the Battle of Tsushima Strait and the Naval Battle of the Sea of Japan (Japanese: 日本海海戦, "Nihonkai-Kaisen") in Japan, was a major naval battle fought between Russia and Japan during the Russo-Japanese War.  It was naval history's only decisive sea battle fought by modern steel battleship fleets, and the first naval battle in which wireless telegraphy (radio) played a critically important role.  It has been characterized as the "dying echo of the old era – for the last time in the history of naval warfare, ships of the line of a beaten fleet surrendered on the high seas".

Battle of Ginnis: The Battle of Ginnis (also known as the Battle of Gennis) was a minor battle of the Mahdist War that was fought on December 30, 1885, between soldiers of the Anglo-Egyptian Army and Mahdist Sudanese warriors of the Dervish State.  The battle was caused by the Mahdist blockade of the Ginnis-Kosha fort, which British commanders hoped to relieve.  The fighting resulted in a British victory.  It is principally remarkable as the last battle fought by the British Army in red coats (although a maxim battery from the Connaught Rangers is said to have fought in red at the Battle of Ferkeh in 1896).
