of it. The remaining were chiefly Italian (4205), Spanish (3406), Argentine (2.553), Portuguese (659), English (606) and Brazilians (492). Oribe, with the support of the then conservative Governor of Buenos Aires Province Juan Manuel de Rosas, besieged the Colorados in Montevideo, where the latter were supported by the French Legion, the Italian Legion, the Basque Legion and battalions from Brazil. Finally, in 1851, with the additional support of Argentine rebels who opposed Rosas, the Colorados defeated Oribe. The fighting, however, resumed in 1855, when the Blancos came to power, which they maintained until 1865. Thereafter, the Colorado Party regained power, which they retained until past the middle of the 20th century. After the end of hostilities, a period of growth and expansion started for the city. In 1853 a stagecoach bus line was established joining Montevideo with the newly formed settlement of Unión and the first natural gas street lights were inaugurated. From 1854 to 1861 the first public sanitation facilities were constructed. In 1856 the Teatro Solís was inaugurated, 15 years after the beginning of its construction. By Decree, in December 1861 the areas of Aguada and Cordón were incorporated to the growing Ciudad Nueva (New City). In 1866, an underwater telegraph line connected the city with Buenos Aires. The statue of Peace, La Paz, was erected on a column in Plaza Cagancha and the building of the Postal Service as well as the bridge of Paso Molino were inaugurated in 1867. In 1868, the horse-drawn tram company Compañía de Tranvías al Paso del Molino y Cerro created the first lines connecting Montevideo with Unión, the beach resort of Capurro and the industrialized and economically independent Villa del Cerro, at the time called Cosmopolis. In the same year, the Mercado del Puerto was inaugurated. In 1869, the first railway line of the company Ferrocarril Central del Uruguay was inaugurated connecting Bella Vista with the town of Las Piedras. During the same year and the next, the neighborhoods Colón, Nuevo París and La Comercial were founded. The Sunday market of Tristán Narvaja Street was established in Cordón in 1870. Public water supply was established in 1871. In 1878, Bulevar Circunvalación was constructed, a boulevard starting from Punta Carretas, going up to the north end of the city and then turning west to end at the beach of Capurro. It was renamed Artigas Boulevard in 1885. By Decree, on 8 January
