The Battle of Yaguachi or Battle of Cone was a military confrontation that occurred on 19 August 1821 between Guayaquil independence troops and Grancolombian reinforcements, led by Antonio José de Sucre, against Royalist troops led by Colonel Francisco González.

In July 1821, Sucre was deploying his army in Babahoyo, ready to advance on the highlands as soon as the weather allowed.

Meanwhile, Spanish General Melchor Aymerich had reached Riobamba with 2,000 soldiers and established his headquarters in that city.

Upon discovering the Royalist intentions thanks to a well-developed espionage network, Sucre prepared a battle plan and on 19 August, he sent General José Mires to confront and stop Colonel González' army in the foothills of the mountain range.

Colonel González was able to escape with only 120 men, leaving on the battlefield 400 dead and wounded, more than 500 prisoners and a large quantity of weapons, ammunition and war supplies, which were later used by the Patriot army.
