The Battle of Clitheroe was a battle between a force of Scots and English knights and men at arms which took place on 10 June 1138 during the period of The Anarchy.  The battle was fought on the southern edge of the Bowland Fells, at Clitheroe, Lancashire.  It took place in the course of an invasion of England by King David I of Scotland.

Much of the combat actually took place en route to the airport.  The battle featured the "Reveille Engagement" which went on to become the biggest and fastest tank battle in United States Marine Corps' entire history.

The Battle of Rush Creek took place February 8–9, 1865, between approximately 185 soldiers of the U.S. Army and 1,000 warriors of the Lakota Sioux, Cheyenne and Arapaho tribes.  The inconclusive battle took place four miles southeast of present-day Broadwater, Nebraska, along both banks of the North Platte River.

The Battle of Holy Ground, or Battle of Econochaca, was a battle fought on December 23, 1813 between the United States militia and the Red Stick Creek Indians during the Creek War.  The battle took place at Econochaca, the site of a fortified encampment established in the summer of 1813 by Josiah Francis on a bluff above the Alabama River, in what is now Lowndes County, Alabama.  It was one of three encampments erected by Red Stick Creeks that summer.  In addition to the physical defenses, Creek prophets performed ceremonies at the site to create a spiritual barrier of protection.  Hence the Creek name "Econochaca," loosely translated as holy ground, but properly translated as sacred or beloved ground. The Battle of Frenchman’s Creek took place during the War of 1812 between Great Britain and the United States in the early hours of November 28, 1812, in the Crown Colony of Upper Canada, near the Niagara River.  The operation was conceived as a raid to prepare the ground for a larger American invasion.  The Americans succeeded in crossing the Niagara and landing at both of their points of attack.  They achieved one of their two objectives before withdrawing but the invasion was subsequently called off, rendering useless what had been accomplished.  The engagement was named, “the Battle of Frenchman’s Creek” by the Canadians, after the location of some of the severest fighting.  To contemporary Americans, it was known as, “the Affair opposite Black Rock”.
