The successful advance of the Primera Junta's troops continued to the North of Upper Peru and on June 20, 1811, they met again near the Desaguadero River where battle ensued.

The aim was to distract Goyeneche's troops on their front and right flank while surrounding the royalists on their rear through the lines established by this new bridge.

The bad impression that this defeat caused in Buenos Aires, where they had lost their guns, resulted in González Balcarce and Castelli being relieved of their commands and court-martialed.

The defeat also caused a cease-fire in the siege at Montevideo due to the concern in Buenos Aires of being attacked from two fronts at the same time.

It forced him to take extreme measures and mobilize Northern Argentina's population in Jujuy Province towards the south before the imminent Spanish offensive.
