Cockade of Argentina

It was also documented by Spanish functionary Faustino Ansay that when news of the revolution arrived to Mendoza, its supporters started to wear white stripes.

[4] In any case, it is known that in March 1811 the Patriotic Society created by people from Mariano Moreno's circle wore the white and light blue ribbons.

In a note dated February 13, 1812, Manuel Belgrano solicited the triumvirate the use of the white and light blue national cockade, having to omit red since the Spanish troops and the royalists had been using it as a distinctive colour against the revolution.

[5] On February 18, 1812, the government decided to create the national cockade of the United Provinces of the Río de la Plata with light blue at its outer border and centre, and white between both.

That day the triumvirate ordered Belgrano to take charge of the Northern Army (Ejército del Norte) and as a result of his immediate departure, he did not become aware that the government had rejected the new flag.
