A short period of peace followed. Puny are the efforts of man at killing each other when heaven fires its artillery! The exhausted state seemed unable to continue its suicidal course. The tranquillity was broken, however, though only for a short time, in 1837.[IX-47] The assembly had, on the 21st of February, 1835, recognized José Zepeda and José Nuñez as the duly elected jefe and vice-jefe respectively. Colonel Zepeda was a distinguished patriot, who had rendered important services to the cause of liberty. His election was hailed with approval in Nicaragua, and in the other states of the union. He took possession of office April 23, 1835.[IX-48] The government experienced no serious difficulty during 1836 in the administration of public affairs. It was engaged in improving the public roads, and in other matters of general utility. But 1837 was inaugurated with infamous crimes, with the murders of the jefe Zepeda, and of the citizens Roman Valladares, Evaristo Berríos, and Pascual Rivas, which resulted from a revolt of the garrison at Leon.[IX-49] The movement was promptly suppressed, and the ringleader, Braulio Mendiola, executed. The vice-jefe, Nuñez, assumed rulership, and during his administration a second constituent assembly was convened, and commenced its labors on the 31st of March, 1838.[IX-50] One month later, on the 30th of April, the state seceded from the federation, an act which may be called a mere formality, inasmuch as Nicaragua had not taken part, to any notable degree, in the affairs of the general government. Nominally, however, the idea of a union of the Central American states was upheld, and still expressed in the new state constitution framed by the assembly and confirmed on the 12th of November, 1838.[IX-51] All this was pure affectation, however, for Nicaragua lent her hearty aid to eradicate the last remnants of the federation. The coveted sovereignty was attained at last. Later events will show whether or not it brought Nicaragua prosperity. The present generation had grown up midst the noise of war, hearing the battle-cry of one or another contending party, and it could hardly be expected that it could appreciate the blessings of peace.[IX-52] * * * * * [Sidenote: EVENTS IN COSTA RICA.]
