Clashes between armed groups in Colombia kill at least 52 guerrillas on eve of election

San Francisco, April 6--The Chronicle says: Private advices received by the steamer City of Sydney from Panama state that the revolution in Colombia is far from ended, and that the rebels are steadily gaining strength. About the 13th of March General Ulioa, at the head of rebel troops, had a fierce battle in Caparrapí state of Cundinamarca, in which the capital city of Bogota is situated. The government troops were defeated and 80 prisoners, 500 rifles and twenty-five cases of ammunition were left in the rebels' hands. General Ramon Metro has won several victories over government troops. Ibañez keeps up the fighting in Cundinamarca and Tolima. In those two states there are reported to be 5000 rebels. Generals Metro and Delgodillo have captured Moniquirá, with 250 government soldiers. Generals Colmenares, Ulioa and Escobar, after marked victory at La Palma against 1,300 government troops, have taken positions in Pacho and San Cayetano with 1,500 men. The situation at Panama is becoming worse and the government is again thinking of leaving the interior to the rebels, or liberals, as they term themselves. The rebel forces in the interior of Panama now number 1000 men, of which 600 are armed, but as soon as the rebels receive the arms and ammunition they have purchased, an army of 5000 men will be available to move against Panama. The revolution has been in progress since Oct. 5, 1899.
