TO feed the millions of fighting men in both armies during the years 1861 to 1865, was an enigma equalled only by the problem of ammunition. After the diets of hardtack on the long marches there is no memory dearer to the heart of the old veteran than a good, old-fashioned "square meal" from the log-cabin kitchen in the camp. This is a typical scene of one of these winter camps. They were substantially built of logs, chinked in with mud and provided on one end with a generous mud chimney and fireplace. The most "palatial" afforded a door and a window. Roaring fires burned on the hearths. With the arrival of the soldiers, knapsacks and traps were unpacked. The canteen was hung on its proper peg. The musket found its place on the wall. The old frying pan and tin cup were hung near the fire. There was to be a real "old home feast." The soldiers crowded around the sutler's tent dickering over canned goods and other luxuries which cost perhaps a half-month's pay. The log settlement was all astir. Smoke issued from the mud chimneys. Crackling fires and savory odors lightened the hearts of the warriors and the community of huts rang with jovialty, laughter and song. Stories of the conflict were told as the soldiers revelled over the hot and hearty meal and not until the late hours did the tired comrades wrap themselves in their blankets and fall onto their beds of pine needles or hard board bunks. THE charge of the cavalry is an intense moment on the battlefield. At the time of the Civil War nothing was known of the snap-shot process in photography and Brady tried frequently throughout the four years to secure negatives of the cavalry. It seems to have been an impossibility under the long "time exposure process." He did, however, succeed in securing negatives of horses. Frequent opportunity to try to secure a photograph of the cavalry, is proven by the fact that there were 3,266 troops, or more than 272 regiments, in defense of the Government. This picture is found in Brady's collection and shows the cavalry depot at Giesboro Point, Maryland, just outside of Washington. At the beginning of the war the mounted men were used as scouts, orderlies, and in outpost duty. General "Joe" Hooker finally turned a multitude of detachments into a compact army corps of 12,000 horsemen. The gallant horseman, "Phil" Sheridan, under instructions from General Grant, organized three divisions of 5,000 mounted men, each armed with repeating carbines and sabers. It was with this force that Sheridan met the Confederate cavalry at Yellow Tavern, near Richmond, and demonstrated the importance of mounted troops by great military powers. One of the most magnificent scenes in the war was when 10,000 horsemen moved out on the Telegraph Road leading from Fredericksburg to Richmond, and the column, as it stood in "fours," well closed up, was thirteen miles long and required four hours to pass a given point.
