The Chilean opposition advances candidate José María…
April 1851 CE
Concerned that the election might not end in their favor, Cruz and other opposition groups decide to attempt a military coup, to be carried out in Santiago by Colonel Pedro Urriola Balbontín.
At dawn on April 20, 1851, Urriola and his companions seize the main streets of Santiago and storm the army barracks to arm more men, but few of the hoped-for soldiers join in the uprising.
Two loyalist battalions organize to face the rebels and prepare a counteroffensive from the Alameda and Santa Lucia Hill.
The fighting lasts about five hours, after which Urriola is killed along with more than two hundred others.
