The questions affecting the prerogatives of the members of Congress and cabinet ministers, together with the extravagant policy of the administration caused much political agitation and exciting debate in the Senate and House of Deputies. The constant attack of the clerical party, the bitter denunciations of the press, added to the conservative opposition finally created dissension among the liberals, who had elected and until then supported the president. Charges of usurpation of power and dictatorship were made against Balmaceda, and the political situation became such that a revolt was imminent. Various ministries had been rejected by Congress because of the policy pursued in erecting costly public works instead of employing the government revenues in reducing the foreign debt and redeeming the paper currency, and the president found himself in the embarrassing situation of having entered upon a policy of extensive government improvement and industrial development without the support of Congress. An extraordinary session was called for the purpose of providing government revenues. Other measures were taken up by Congress and the appropriation bill deferred until the president should recede from his arbitrary position. Balmaceda refused to compromise, and the ministry again resigned. He then appointed a new cabinet in harmony with his views and declared the session closed, maintaining that Congress when called in extraordinary session for the express purpose of passing an appropriation bill had no constitutional authority to go into the consideration of other measures. In explaining his action he said: “Congress by the express terms of the constitution has no more right to dictate to me what ministers I shall appoint than it has to advise what food I shall eat or clothes I shall wear.”

The Constitutional Advisory Committee was convened and as a result of its deliberations the president was advised to again convene Congress in extraordinary session. Balmaceda hesitated, fearing that Congress if again convened might declare the office of president vacant. While he and his ministers deliberated, the Constitutional Committee arrogated to itself the authority to call an extra session. The opposition was rapidly securing support from various political elements throughout the country and by popular sympathy among the people. The dictatorial attitude of the administration aroused intense feeling and there was a clamor for the deposition of the alleged dictator. Realizing that summary action was necessary to maintain his power and aggressive policy, the president issued a manifesto on January 1, 1891, declaring his intention to exercise his constitutional powers and functions,—to stand by the strict letter of the law. He declared that he had nothing to do with the effete provisions of the constitution, nor with new theories of parliamentary government until they were enacted into law. He maintained that under the constitution the appropriation bill passed by the previous Congress held good until another was passed. The supreme court declared the acts of the president unconstitutional. He ignored the court. This assumption of authority on the part of the executive was contrary to precedent and to republican ideas, even if constitutional, and the cry of “dictator” was raised. Thus the machinery of government was disabled, and while the Ship of State lay stranded upon the rock of party politics, Congress declared the country in revolution, and the tempest of war struck the Republic on January 7, 1891, when the navy, under command of Señor Don Jorge Montt went over to the revolutionists. The squadron sailed for the north with the presiding officers of the Senate and House of Deputies on board, and a floating Congress was established.

The Congress which declared Balmaceda deposed, empowered Don Jorge Montt to assume provisional command, and a junta was organized on board the warship Blanco Encalada, composed of Señor Montt, Don Waldo Silva, vice-president of the Senate and Don Ramon Barros Luco, president of the Chamber of Deputies.

The revolution started by Balmaceda’s manifesto of January 1, 1891, was apparently poorly prepared to cope with the government. The insurgents had no military organization, no arms or munitions of war. The junta proceeded north and took possession of the provinces of Tarapaca, Atacama and Antofagasta, which include the rich nitrate fields and wealth producing mineral territory of Chile, the revenues from which were employed in purchasing arms, provisions and equipment for an army. They also had possession of the majority of the naval squadron. By the middle of the year 1891 the government had 45,000 troops in the field, four thousand of which were cavalry. The revolutionists had only about twelve thousand soldiers, which encouraged the sanguine Balmaceda to believe that he could easily suppress the uprising.

Congressional elections were held in May, and a majority of the members elected were in sympathy with the administration. In June presidential electors were chosen, and they selected as the candidate for president Don Claudio Vicuña, who was Balmaceda’s choice for his successor. Señor Vicuña, who was of an old and distinguished family, was declared duly elected president on July 25, 1891, but the final success of the insurgents prevented him from ever taking his seat.

As the struggle continued the revolutionary cause gained strength and reinforcements from various sources. The superior skill of the military officer directing the opposition forces made itself manifest, and the position of Balmaceda and his government became daily more and more menaced with dissolution and overthrow. On August 20, ten thousand revolutionary troops were disembarked at Quintero, a few miles from Valparaiso, and on the following day a decisive battle was fought, at Concon, situated at the mouth of the Aconcagua River, resulting in the defeat of the government forces. This crushing defeat, in which about 2,500 of the government troops were killed, practically caused the fall of Balmaceda. He made a strenuous and brave effort to recover from the disaster, but the railway communication having been destroyed, it was impossible to send reserve troops from the south, where they had been stationed, in time to save the situation.

After the battle of Concon the opposition forces advanced upon Valparaiso, and two days later endeavored to capture Fort Callao, at Viña del Mar, a beautiful suburban place six miles from Valparaiso. The fortress, which commands the bay of Valparaiso, the valley and surrounding heights, being equipped with modern guns, and well-nigh impregnable, resisted the attack of both warships and artillery, and a repulse prevented a direct advance upon Valparaiso, the objective point of the Congressional army. Retiring from Viña del Mar, Generals Canto and Korner, commanding the revolutionary forces, fell back to Salto, a few miles distant, where they destroyed a railway bridge spanning the river, thus cutting off communication with Santiago, and preventing the possibility of Balmaceda forwarding troops from the capital. Making a detour of some thirty miles, the revolutionists endeavored to approach Valparaiso from the south, but encountered the government forces, under command of Generals Barbosa and Alzerreca, occupying a formidable position upon the hills near Placilla, a few miles from the city of Valparaiso. This was on August 27th. On the 30th the election of Señor Claudio Vicuña would be formally ratified by the Senate, and he would become president. It was important to the revolutionists to force a decisive engagement and overthrow Balmaceda before the newly elected president should take his seat. Before daylight on the morning of the 28th, under cover of the darkness and protection of the hills, the revolutionists got into position to give battle without being seen by the government forces. Early in the morning as the advancing army was crossing an open plain Balmaceda’s troops opened an artillery fire upon it, and the battle of Placilla, the final and decisive engagement in the revolution, was begun. The opposition forces numbered about twelve thousand and the government, nine thousand. The former, flushed with success and inspired with the hope of final victory, fought like demons, while the latter, discouraged and disheartened with failure, menaced with disaster and annihilation, showed lack of order, discipline, and courage manifested and displayed on previous occasions. Some companies even deserted and joined the enemy during the battle. After a few hours’ terrific fighting, in which more than a thousand men were killed and a greater number wounded, on the government side, the Balmaceda army was put to rout. The victorious forces which had lost five hundred killed and over a thousand wounded, pursued the fleeing remnants of the routed army, driving many of them into the quebrades (ravines), where they were unmercifully slaughtered. Generals Barbosa and Alzerreca were both killed in the engagement. On the evening of the 28th, Valparaiso was in possession of the revolutionists and the Balmaceda government was overthrown.

Leading government supporters, including Don Claudio Vicuña, president elect, and who only lacked a few days of being formally declared the chief executive of the Republic, sought refuge on board foreign warships in the harbor.

That night Valparaiso was the scene of a Bacchanalian rabble that would have shamed Rome in the reign of Nero. The city was in possession of a mob, intoxicated with success, drunk upon wine and athirst for blood, that murdered with impunity and sacked the town without restraint. Drunken men and women reeled through the streets, shooting at each other as a matter of sport, and on the following morning four hundred victims of the mob’s violence were found dead in the streets.

The scenes enacted in Santiago were equally as wild and tragic as those witnessed in Valparaiso. The houses of Balmaceda, Claudio Vicuña and other Balmacedistas were attacked, looted and everything they contained destroyed or carried away. A statue of the deposed president was dismembered and kicked through the streets. From balconies ladies cheered the performance, while opprobrium was heaped upon the inanimate form by the drunken mob. Beggars and thieves appropriated with impunity works of art and beautiful articles of furniture found in the residences of those who had remained loyal to the administration.
