As soon as the work of preparation at Cedar Point was well under way, I accepted the invitation of Captain Carter to make a reconnoissance in the "Michigan." We sailed out of the harbor and made the tour of the beautiful group of islands known as the Bass Islands, in the midst of which is the little harbor of Put-in-Bay. We were on the classic ground where Perry had won his naval victory in the War of 1812, and although we found no trace of the threatened raid, the circumstances which took us there added to the interest with which we examined the scene of Perry's glory. On my return I reported to the Secretary of War that all present danger had passed, and asked to be allowed to send the militia home. The weather had become stormy, and the State troops naturally became impatient when the need of their continued exposure seemed to be at an end. They were soon allowed to go, but it was wisely determined to put the heavy guns in a fortification on the island, where they could command the entrance to the bay and yet be so connected with the permanent garrison as to avoid the establishment of two camps with the necessary increase of expense as well as numbers. This delayed me a fortnight at Sandusky, and the delay was quite as unwelcome to me as to the militia. I had been away from Cincinnati but a few days when I received a dispatch from General Burnside, saying that if I was still minded to accept a field command he thought he could give me one of his corps. As this was exactly what I had been wishing for, it will be easily believed that I chafed at the circumstances which seemed to tie me to the shore of Lake Erie when I longed to be on my way to East Tennessee. I laid the matter before the War Department by telegraph, and begged to be allowed to go. Mr. Stanton answered on the 22d that I could not yet leave Sandusky. I hurried the work to be done there with all possible energy, so as to remove the cause of delay, and on the 3d of December was gratified to learn that the order had been issued directing me to report in person to the general in command at Knoxville. I was not informed that I should not find Burnside there when I should arrive, and assumed that my work at Sandusky was the only cause of delay in my orders to go; but I was soon to learn of other changes which I did not anticipate.
