I immediately communicated with Governor Tod and with the Commissary of Prisoners at Washington, Colonel Hoffman, and on the same day sent a battery of three-inch rifled cannon and 500 newly raised recruits to Sandusky. I telegraphed the Hon. Joshua R. Giddings, our consul-general at Montreal, asking what he could learn in Canada as to the threatened expedition. He thought it was the mere "bombast" of Confederate emissaries and refugees in the Canadian provinces, and made light of it. On the 12th, however, the Secretary of War telegraphed me that Lord Lyons, the British ambassador, confirmed the report, and directed me to take energetic action to defeat the expected raid. The dispatch reached me at nine o'clock in the morning, and as it would be necessary to consult with the governor and get him to call out a force of State militia, I telegraphed him that I would go to Columbus on the half-past-ten train from Cincinnati, and asked him to be ready to call out the militia as soon as I could see him. I then sent messages to the commandants of militia regiments near the railway line, requesting them to call out their men at once in anticipation of an order from the governor to proceed to Sandusky. I also communicated with my subordinates in command at Detroit, Sandusky, and Columbus, giving a hint of my purposes. Finding I was likely to be late at the railway station, I sent a message to Mr. Woodward, the superintendent of the Little Miami Railroad, asking him to hold the train for me. The train had gone when the message reached him, but he ordered out an extra locomotive, and when I reached the station it was under orders to overtake the regular train. With an aide-de-camp I mounted the locomotive, and we were off at speed. The train was overtaken at Xenia, half-way to Columbus, and I was able to keep my appointment with the governor. It happened that there was at this time a plot also to take the camp of military prisoners at Columbus, indicating a wide-spread scheme among the Confederate prisoners in Ohio, and General Mason, who commanded there, did not think it would be safe to reduce his garrison. The governor acted at once upon my suggestion, and ordered out the militia regiments which I had warned before leaving Cincinnati. My regular train had gone on, but Mr. Woodward had provided for a special one from Columbus, and we were soon speeding on in the hope of making the connection with a train going West on the Lake Shore Railway. The connection was made, though it became necessary to make what was then regarded as extraordinary speed to do it. Over one stretch of the road we ran twenty miles in eighteen minutes by the watch, and our average rate was high enough to make it a noteworthy journey. I reached Sandusky at midnight, and found reports of the militia regiments already on the way, and that the hostile expedition had not yet left Canada.
