Barclay, like
Owen Brown and
Francis Jackson Meriam, did not enter Harpers Ferry; they remained at the
Kennedy Farm guarding the weapons. When it became clear that the raid was failing, they escaped northward, after much difficulty reaching
John Brown, Jr.'s house in
Ashtabula County, Ohio. Barclay continued to Canada, later returning to Springdale, Iowa, where his mother lived. On January 23, 1860, about three months after the Harpers Ferry raid, Iowa governor
Samuel Kirkwood received from the governor of Virginia a requisition "for one Barclay Coppock, reputed to be a fugitive from the justice of Virginia". Kirkwood found the requisition deficient in legal form and returned it to Virginia. Barclay was gone to Canada by the time Kirkwood received the corrected papers. He later returned to
Ashtabula County, Ohio, where
John Brown Junior lived, and where raiders Owen Brown and
Francis Merriam were taking refuge. A newspaper story reports that they were all registered to vote there. Barclay, along with Owen, addressed a meeting the day of Hazlett's and Stevens' executions. Barclay later joined the
Union Army during the
American Civil War and served as a recruiting officer. He was killed in action when Confederate sabotage derailed his train over the
