Background and detail

Background. Following the failure of an armistice in 1811, a second siege of Montevideo began in 1812. The front remained static until 1814 due to royalist control of surrounding rivers. In early 1814, executive power was concentrated on the Supreme Director. Royalist commander Jacinto de Romarate fortified Martín García Island to secure a base for attacks on Colonia del Sacramento, parking a flotilla of nine vessels with artillery.

Naval Engagement. On 8 March 1814, William Brown sighted royalist brigantines near Colonia del Sacramento. On 10 March, his ships, including the Hercules, faced the Spanish fleet commanded by Captain Jacinto de Romarate. A furious battle ensued within 48 hours of Brown taking his ships to sea. The engagement involved multiple vessels such as the Julieta, Tortugas, and Fortunata.

Outcome. The battle lasted from 10 to 15 March 1814. Admiral William Brown subsequently landed on the island and defeated the royalists, leaving Martín García in the hands of the United Provinces of the Río de la Plata.
