The revolutionary forces under Miranda were signally defeated by the Guatemalan commander, Solares, on the north side of the Chamelecon River on the 9th of August, with great loss, General Casto Alvarado and Colonel A. Muñoz being killed, and a large quantity of war material falling into the victor's hands.[XXII-25] The presidents of Guatemala and Salvador, after the insurrection in the former republic had been quelled, held conferences at Chingo on the situation in Honduras, and came to the conclusion that Arias' government, being unpopular, could not sustain itself without their material as well as moral support, which would be a heavy burden. He was then asked in a joint note to give up the executive office to some one more in the confidence of the people. He refused to accede to the demand, and the allied troops approached Comayagua to carry out their suggestion. The first notice of their intent was the proclamation in the town of Aguanqueterique, of Ponciano Leiva as provisional president, who organized his administration at Choluteca on the 23d of November, and on the 8th of December declared all the acts of Arias null.[XXII-26] The allied forces of Leiva under his minister of war, General Juan Lopez, of Guatemala under Solares, and of Salvador under Espinosa, laid siege to Comayagua on the 6th of January, 1874, and after seven days' resistance, Arias, together with his ministers and chief supporters, had to capitulate on the 13th. Ex-president Medina was released from confinement, and eventually, having recognized the new ruler, was set free, when he went to live in La Paz.[XXII-27] [Sidenote: LEIVA SUCCEEDS ARIAS]
