Spain
With the outbreak of the Spanish Civil War, Peadar O'Donnell and then George Gilmore went to Spain on behalf of the Congress to report on proceedings, and returned enthusiastic supporters of the Spanish Republicans. Ryan was incensed at quasi-Fascist Eoin O'Duffy organising an Irish Brigade to fight with the Fascists, and in open letters to the papers criticised Cardinal MacRory for raising funds at church collections to support Franco.

The first men left Dublin, Belfast, and Rosslare ports in early December 1936 traveling through France and Britain to Spain.
