Francisco Cruzat was the son of Balthazar and Francesca Cruzat. He joined the Spanish Army in his youth and came to Louisiana with Lieutenant Gen Alejandro O'Reilly in 1769 as a captain of grenadiers. Cruzat arrived at St. Louis on May 20, 1775. Cruzat became the lieutenant governor of Upper Louisiana in 1775. He continued the same enforcement of Spanish policies as his predecessor, Pedro Piernas. During his tenure the first ferry was established in Maramec, by a man named John Baptiste Gamache. In 1778, Cruzat was removed from office on the orders of Louisiana GovernorBernardo Galvez, and was replaced by Fernando de Leyba. In 1779, Cruzat took part in the conquest of Baton Rouge, and in early 1780 he gained the rank of lieutenant colonel. In September 1780, Francisco Cruzat was reappointed lieutenant governor of Upper Louisiana after the death of Fernando de Leyba in June earlier that year. Only a few months later in January 1781, Cruzat dispatched an attack on Fort St. Joseph near Lake Michigan in response to rumors of a spring attack on St. Louis by the British. His force was commanded by Captain Eugenio Pourré and included about 140 Spanish soldiers and 60 Native American volunteers. The militia also included Ensign Charles Tayon and the interpreterLouis Chevalier. Cruzat and his forces successfully captured Fort St. Joseph on February 12, 1781. On November 27, 1787, Cruzat left his office of lieutenant governor of St. Louis and was succeeded by Manuel Pérez. In 1789 he served as Interim Governor of East Florida, temporarily replacing an unwell Arturo O´Neill who had requested a leave of absence. O'Neill organized the Third Battalion of Pensacola in 1790, which Cruzat was assigned to command, and Cruzat continued that assignment until he died.
Personal life
Cruzat married Nicanora Ramos, a native of Cartegena, Spain. They had four children together, Antonio, Francois, Josefa and José. There is little mention of Francois, and in Cruzat's first term as lieutenant governor of Upper Louisiana, his daughter Josefa died while still a young child and was buried in the church cemetery. Their two surviving sons were Antonio and José. In May 1782, his wife and their two sons were captured by British allies near present-day Memphis, Tennessee while they were en route to St. Louis. Cruzat was able to negotiate their release for a ransom of 4500 pesos. His wife died in St. Louis in 1786, and Cruzat died in Pensacola, Florida in 1790.
