El Sordo, also known as Santiago, is an older man and a leader of another guerilla group that Robert Jordan, Pilar, and the other guerillas enlist to help with the upcoming offensive on the bridge. El Sordo means “the deaf one” in Spanish, referring to El Sordo’s partial deafness; though handicapped, he is a determined fighter, similar to Pilar and Robert Jordan, and he is not afraid of death or committing acts of violence. His guerilla group is stronger and more organized than Pilar’s, though they are still defeated easily by the fascists, suggesting that no Republican, no matter how dedicated, can successfully resist the fascist forces.
