Spanish (3406), Argentine (2,553), Portuguese (659), English (606) and Brazilians (492). During this time Uruguay had two parallel governments: Gobierno de la Defensa in Montevideo, led by Joaquín Suárez (1843–1852) Gobierno del Cerrito (with headquarters at the present neighbourhood Cerrito de la Victoria), ruling the rest of the country, led by Manuel Oribe (1843–1851) The British Empire eventually saved the city by allowing it to receive supplies. First, the British and French naval forces temporarily blockaded the port of Buenos Aires during December 1845. Then, the French and British fleets protected Montevideo from the sea. French, Spanish and Italian legionnaires, led by Giuseppe Garibaldi, teamed up with the Colorados in defending the city. Also in 1846, the 73rd (Perthshire) Regiment of Foot, sent by Britain, arrived in Montevideo and defended it for seven months against besieging Argentine troops. Historians believe that the French and British forces intervened in the region to ensure free navigation along the Rio Parana and Rio Uruguay. However, in 1850, both the French and British withdrew after signing a treaty which represented a triumph for Juan Manuel de Rosas and his Federal Party in Argentina. After the withdrawal of British and French troops, it appeared that Montevideo would fall to Juan Manuel de Rosas and Oribe. However, an uprising against de Rosas led by fellow Federalist Justo José de Urquiza, governor of Argentina's Entre Ríos Province, with the assistance of a small Uruguayan force, changed the situation completely. Manuel Oribe was defeated in 1851, leaving the Colorados in full control of the country. Brazil followed up by intervening in Uruguay in May 1851, supporting the Colorados with financial and naval forces. This led to the Platine War with Rosas in August 1851. In February 1852, after being defeated at Caseros, Rosas resigned and Urquiza's pro-Colorado forces lifted the siege of Montevideo. Aftermath The government of Montevideo rewarded Brazil's financial and military support at the final stages of the war by signing five treaties in 1851 that provided for perpetual alliance between the two countries. Brazil was required to extradite runaway slaves and criminals from Uruguay. In fact, during the war, both the Blancos and the Colorados had abolished slavery in Uruguay to reinforce their respective military forces. The treaties also allowed joint navigation on the Rio Uruguay and its tributaries and exempted cattle and salted meat exports from taxes. The Uruguayan cattle industry was devastated by
