Joseph I of Portugal
Over the next decade, Portugal reoccupied Rio Grande do Sul in an undeclared war before formal hostilities commenced in the 1776-1777 Spanish–Portuguese War. In February 1777, a Spanish expeditionary force of 116 ships and 19,000 troops captured the island of Santa Catarina in February before moving against Colonia del Sacramento which surrendered in July. Fighting ended in February 1777 when Joseph I of Portugal died and his daughter, Spanish-born Maria I, sued for peace.
