Louis S. Gerteis, "Stearns, George Luther," American National Biography Online, February 2000, http://www.anb.org/articles/04/04-00946.html.
After Brown's raid on the federal arsenal at Harpers Ferry, Stearns and a fellow conspirator, Samuel Gridley Howe, fled briefly to Montreal. But Stearns returned to defend his actions before a Senate committee investigating the role of "subversive organizations." He admitted that he supported Brown's efforts to "go into Virginia or some other state and relieve slaves," but he denied any knowledge of plans to commit treason against the United States. The committee uncovered no evidence to indicate that Stearns or anyone else outside Brown's raiding party had such knowledge.
