British square is a military formation used by the British army during the 18th and 19th centuries. During a battle, soldiers would form a square with their backs to each other to protect themselves from cavalry charges. Some synonyms for British square might include infantry square or infantry box formation. Other similar formations include the Spanish square, French square, and the Huguenot square. These formations were used by different armies with slight variations in positioning, but the basic concept remained the same - to create a defensive formation that could repel enemy attacks. Though the use of these formations declined with the advent of new military technologies, they remain an important part of military history.
