Our camp had been moved onward from Murfreesboro' to Shelbyville, which is a beautiful little city, situated on Duck river. We camped above the town, in a delightful meadow. It was Sabbath, the 6th of April, and the earliness of the clime made the birds sing, and the fields bloom with more than the brilliancy of May in our own northern land. Deeply is the quiet of that Sabbath, with the green beauty of the warm spring landscape, pictured on my mind! An impression, I know not what, made me devote the day to writing letters to my friends. It was well I did so, for long and weary months passed ere I was permitted to write to them again. But while the day was passing in such sweet repose with us, it was far different in another army; that was the day on which Grant was surprised by Beauregard, and only saved from destruction by the assistance of the gunboats. This, however, we did not learn for several days after. On Monday, Andrews returned to our camp. He had spent some time along the line of the Georgia State road, and on his return reported to General Mitchel that the scheme was still feasible, and would be of more advantage than ever. He, however, asked for a larger detail of men, and twenty-four were given from the three Ohio regiments then in Sill's Brigade. One man was detailed from a company, though all the companies were not represented, and I believe in two[1] instances, two men were detailed from one company--they were probably intimate friends, who wished to go together. [1] One of these I noticed only very lately.
