After Carrera returned from exile in 1849 the president of El Salvador, Doroteo Vasconcelos, granted asylum to the Guatemalan liberals, who harassed the Guatemalan government in several different ways. José Francisco Barrundia established a liberal newspaper for that specific purpose. Vasconcelos supported a rebel faction named "La Montaña" in eastern Guatemala, providing and distributing money and weapons. By late 1850, Vasconcelos was getting impatient at the slow progress of the war with Guatemala and decided to plan an open attack. Under that circumstance, the Salvadorean head of state started a campaign against the conservative Guatemalan regime, inviting Honduras and Nicaragua to participate in the alliance; only the Honduran government led by Juan Lindo accepted. In 1851 Guatemala defeated an Allied army from Honduras and El Salvador at the Battle of La Arada.
