For 13 months, a huge bakery in the Capitol’s basement churned out bread for the United States Army during the Civil War. This print gave readers at home a sense of the enormous operation. Barrels of flour stored in the vaulted crypt rolled down the stairs to the basement. There, they met buckets of liquid yeast made from potatoes. Mixed in long troughs, the resulting loaves went into large ovens that belched smoke, ruining visitors’ clothes and driving researchers from the congressional library just above. The project was nevertheless considered a huge success. Wagons from the Army’s regiments came and went from the loading docks all day long, and the military recorded that the bakery produced 10,707,151 loaves of bread during its existence.
