In the winter of 1878-79 Mapleson undertook a major opera tour of the United States, in which Campanini was his principal tenor. The company also included such well known singers as Etelka Gerster, Minnie Hauk, Trebelli, Valleria, Galassi and Del Puente. Luigi Arditi was the conductor. It visited Washington, D.C., Boston, Chicago, St Louis, Philadelphia, Baltimore, Cincinnati and New York. Campanini sang opposite Gerster in "Il talismano" and "La traviata", and with Marie Roze in "La favorita", and a very wide range of operas was presented including "Faust", "Il flauto magico", "Le nozze di Figaro", "Don Giovanni", "Il barbiere di Siviglia", "Ruy Blas", "Robert le Diable" and "Der Freischütz", in addition to much of the repertoire already mentioned. The series culminated with a benefit concert in New York for flood victims at Szegedin in Hungary (Gerster's birthplace).
