I have been invited to take a tour of Canada by British Maj. Gen. Charles Hastings Doyle. While there, I took the opportunity to look into legal matters concerning Confederates who had fled to Canada during the war. I wrote Sec. Stanton,
Montreal Canada Aug. 8th 1865
Hon. E. M. Stanton,
Secretary of War,
Sir:
Since my arrival here I have seen Mr. Potter, our Consul and find that in his judgment after investigation that the charges made against Dr. Montrose Pollen of trying to extort from a witness in the conspiracy trial a contradiction of his testimony in the case is probably without foundation. As amnesty had been extended to Dr. Pollen, and was revoked in consequence of the charge I would respectfully recommend that he be paroled to go to St. Louis, to await whatever action may be thought necessary in his case. I would also recommend that Mr. Potter our Consul be authorized to parole Gen’l D. M. Frost to go to St. Louis to await action in his case: General Frost voluntarily went before the American Consul at Quebec and took the proper steps and Oath for making his application for Amnesty.
Very respectfully
Your obt. Servt
