GOLD-FILLED FORT is a term used to describe a type of fortification built with gold-filled walls. The term was coined by Major General Henry Knox, who served as the Chief of Artillery in the Continental Army during the American Revolutionary War. Knox was responsible for the construction of many forts and fortifications during the war, some of which were filled with gold. These forts became known as GOLD-FILLED FORTS, and are still remembered today as a symbol of Knox's dedication to the cause of American independence.
