Battle of Lund: The Battle of Lund, part of the Scanian War, was fought on December 4, 1676, in an area north of the city of Lund in Scania in southern Sweden, between the invading Danish army and the army of Charles XI of Sweden.  The Danish had an army of about 13,000 under the personal command of 31-year-old King Christian V of Denmark, aided by General Carl von Arensdorff.  The Swedish army, which numbered about 8,000, was commanded by Field Marshal Simon Grundel-Helmfelt and the 21-year-old Swedish king Charles XI.  It is one of the bloodiest battles in percent of casualties on both sides ever fought on European soil.

Battle of Nibley Green: The Battle of Nibley Green was fought on 20 March 1469 (modern historians would date the battle in 1470 - prior to the adoption of the Gregorian calendar in England the start of the new year was 25 March; the battle being fought on 20 March meant it fell into the previous year), between the troops of Thomas Talbot, 2nd Viscount Lisle and William Berkeley, 2nd Baron Berkeley.  It is notable for being the last battle fought in England entirely between the private armies of feudal magnates.

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.

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".
