    Herbert L. Pratt 81k Under salvage after hitting a mine, June 1918. By the time this view was taken buoyancy had been restored to the ship's forward section and she had raised steam in preparation for going to Philadelphia, Pennsylvania, for repairs. Note the diagonal line on her hull, sloping down and aft from the quarterdeck break, representing the degree to which her bow had been submerged.
