During the French and Indian War (1755–1763) New Jersey's participation was remarkable, and "Colonial Tribulations" (2007) documents the service of the New Jersey Regiment (the "Jersey Blues") throughout that period. Just as in the previous colonial wars their existence began with the N. J. Assembly ordering the muster of 500 men to respond to the larger war looming on the New York frontier. Indian raids by tribes allied with the French along the colony's northwest border in the summer of 1755 also prompted the raising of a different unit known as the New Jersey Frontier Guard (not to be confused with the regular provincial or "Blues" regiment). The Frontier Guard responded to localized Indian incursions, as well as garrisoned the forts along the Delaware River.
