The flag of Carillon was flown by the troops of General Louis-Joseph de Montcalm during the Battle of Carillon, which was fought by the French and Canadian forces against those of the British in July 1758 at Fort Carillon.
Duncan Campbell was a Scots nobleman who died on 18 July 1758 as a result of wounds received in an unsuccessful frontal attack against French forces at Fort Carillon (renamed Fort Ticonderoga when the British took the fort a year later).
 The legend associated with Campbell is that a number of years prior—while still living in Scotland—Campbell gave shelter to a stranger who turned out to have killed Duncan's cousin.
 Faced with the conflict between betraying a guest or taking vengeance for the death of his cousin, Campbell compromised by allowing the killer to hide out in a cave.
 The ghost of Campbell's cousin is claimed to have appeared to Campbell in a dream and promised to meet him again at "Ticonderoga", a place that Duncan surely had never heard of previously.
 This story was published in the poem "Ticonderoga a Legend of the West Highlands" by Robert Louis Stevenson in "Scribner's Magazine" December 1887.
Fort Carillon, the precursor of Fort Ticonderoga, was constructed by Pierre de Rigaud de Vaudreuil, Governor of Canada, to protect Lake Champlain from a British invasion.
 Situated on the lake some fifteen miles south of Fort Saint Frédéric, it was built to prevent an attack on Canada and slow the advance of the enemy long enough for reinforcements to arrive.
Fort Ticonderoga, formerly Fort Carillon, is a large 18th-century star fort built by the French at a narrows near the south end of Lake Champlain, in northern New York, in the United States.
 It was constructed by Canadian-born French military engineer Michel Chartier de Lotbinière, Marquis de Lotbinière between October 1755 and 1757, during the action in the "North American theater" of the Seven Years' War, often referred to in the US as the French and Indian War.
 The fort was of strategic importance during the 18th-century colonial conflicts between Great Britain and France, and again played an important role during the American Revolutionary War.
George Augustus Howe, 3rd Viscount Howe (c. 1725 – 6 July 1758) was a career officer and a Brigadier General in the British Army.
 He was described by James Wolfe as "the best officer in the British Army".
 He was killed in the French and Indian War in a skirmish the day before the Battle of Carillon, an ultimately disastrous attempt by the British to capture French-controlled Fort Carillon.
The Battle of Carillon, also known as the 1758 Battle of Ticonderoga, was fought on July 8, 1758, during the French and Indian War (which was part of the global Seven Years' War).
 It was fought near Fort Carillon (now known as Fort Ticonderoga) on the shore of Lake Champlain in the frontier area between the British colony of New York and the French colony of New France.
Isaac Stearns Jr. (born June 13, 1750; died April 29, 1807), of Billerica, Massachusetts, was a sergeant in the American Revolutionary Army.
 On April 19, 1775, he was among the minutemen who rallied at the first alarm at the onset of the Battles of Lexington and Concord.
 He was also a member of a group of forty men, led by Ethan Allen, that captured Fort Ticonderoga.
 Stearns contributed ₤10 to a fund established to hire men to serve in the Revolutionary Army.
The 1759 Battle of Ticonderoga was a minor confrontation at Fort Carillon (later renamed Fort Ticonderoga) on July 26 and 27, 1759, during the French and Indian War.
 A British military force of more than 11,000 men under the command of General Sir Jeffery Amherst moved artillery to high ground overlooking the fort, which was defended by a garrison of 400 Frenchmen under the command of Brigadier General François-Charles de Bourlamaque.
Fort Mifflin, originally called Fort Island Battery and also known as Mud Island Fort, was commissioned in 1771 and sits on Mud Island (or Deep Water Island) on the Delaware River below Philadelphia, Pennsylvania near Philadelphia International Airport.
 During the American Revolutionary War, the British Army bombarded and captured the fort as part of their conquest of Philadelphia in autumn 1777.
 The United States Army began to rebuild the fort in 1794 and continued to garrison and build on the site through the 19th century.
 It housed prisoners during the American Civil War.
 The army decommissioned Fort Mifflin for active duty infantry and artillery in 1962 however while the older portion of the fort was returned it to the City of Philadelphia; a portion of the fort's grounds are still actively used by the United States Army Corps of Engineers making it the longest fort in military use in the United States.
 Historic preservationists have restored the fort, which is now a National Historic Landmark.
Fort Ellis was a British fort or blockhouse built during the French and Indian War and located at the junction of the Shubenacadie and Stewiacke Rivers, close to Stewiacke, Nova Scotia, Canada.
 (The location was labelled Ville Pierre Hebert by Charles Morris.
 The 14 Acadian families in the area vacated with the Acadian Exodus.)
 Charles Morris recommended a Fort on the Shubenacadie River in 1753.
 Governor Lawrence first considered the fort in 1754 as a means to protect Halifax from Mi'kmaq raids.
 Lawrence decided the fort would not be effective until after the Battle of Fort Beauséjour.
 The fort was completed on October 18, 1761, shortly after the burying of the hatchet ceremony.
 The fort was to guard the new road built to connect Truro and Halifax against Mi'kmaq raids.
 The fort was called Fort Ellis after Governor Henry Ellis, who was appointed governor weeks after the forts completion.
 The fort was never garrisoned and eventually abandoned in 1767.
 (Fort Belcher, named after Governor Jonathan Belcher, was built on Salmon River in Lower Onslow, Nova Scotia (1761-67).
 Fort Franklin was built at Tatamagouche in 1768, named after Michael Francklin and lasted only a year. )
