When revolution erupted in Paris in February 1848, Liebknecht hurried to the scene. He arrived too late to do much in Paris, but he did join a legion that was traveling to Germany to instigate revolution there. During that poorly planned expedition, he was arrested in Baden and charged with treason. On the eve of his trial, revolution erupted once more, and a mob secured his release. He then became a member of the "Badische Volkswehr" and an adjutant of Gustav von Struve and fought in the ill-fated" Reichverfassungskämpfe" ("federal constitution wars"). After the revolutionaries' defeat, he escaped to Switzerland and became a leading member of the "Genfer Arbeiterverein" (Worker's Association of Geneva), where he met Friedrich Engels.
