The Guayaquil revolutionaries decided that their first objective should be the liberation of the capital Quito, and raised an army to this end.

The combat took place in the Camino Real sector, near the small town of Bilován, south of the city of Guaranda.

However, the Royalists had fortified themselves in Camino Real with the aim of stopping the Patriots and after this, organize an attack on the city of Guayaquil itself, and thus end the rebellion within the Royal Audiencia of Quito.

The Guayaquil forces, or the so-called División Protectora de Quito, were commanded by Colonels Luis Urdaneta and León de Febres-Cordero, while the Royalists was led by Colonel Antonio Fominaya.

But in 1821, they obtained help from Gran Colombia and with this they were able to achieve the final objective after a campaign that would last for 2 years.
