He returned to Granada in 1927, and started publishing in the local newspaper "Nicaraguan Daily". A fan of the burlesque and a man of a refined sense of humour, at his 20th Coronel published in his most sarcastic tone the poem “Ode to Ruben Dario” in which he publicly establishes a break from Modernism. Rebel in the content, the poem though is still traditional in its lyric. His “position is both rejection and adhesion, is the disciple’s insurrection against the admired teacher”. About a year later, he led with Luis Alberto Cabrales and Joaquín Pasos Argüello the foundation of the Vanguard Literary Movement, with other young Nicaraguan writers, among them Manolo Cuadra y Pablo Antonio Cuadra, the youngest of the group.
