 Arguments between Bolsheviks and Mensheviks continued after the conference; the Bolsheviks accused their rivals of being opportunists and reformists who lacked discipline, while the Mensheviks accused Lenin of being a despot and autocrat.Enraged at the Mensheviks, Lenin resigned from the "Iskra" editorial board and in May 1904 published the anti-Menshevik tract "One Step Forward, Two Steps Back".The stress made Lenin ill, and to recuperate he went on a hiking holiday in rural Switzerland.
