The revolutionary leader
Simón Bolívar arrived in the island of Margarita in May 1816. On 6 May 1816 Bolívar declared the
Third Republic of Venezuela and an Assembly of Notables recognized Simón Bolívar as Supreme Chief in the church of
Santa Ana. Bolívar then went on to the mainland. That year the Republicans were generally successful in their struggle with the Royalist forces. The Spanish general Pablo Morillo returned to Venezuela in December 1816, and decided to first take Margarita, then move on to
Guayana Province, both important Republican bases. After some difficulties in collecting supplies and troops, Morillo sailed to Margarita in late June 1817, where he steadily gained control in a hard-fought campaign. On 24 July 1817 Morillo occupied the
San Carlos de Borromeo Fortress at
Pampatar, at the southeast tip of the island a few miles from Asunción. The Revolutionaries had evacuated the castle and withdrawn to Asunción, where they concentrated. They were followed by Morillo's forces. The Spanish occupied the hill of Matasiete, which overlooked the city and its surroundings from the east, with a force of 2,000 infantry and 600 cavalry. There was no resistance to this move. The approach to the town was difficult, however, due to the rugged terrain that the defenders had fortified with redoubts, moats and parapets. ==Battle==
