Severely wounded, Preston remained at his gun throughout the engagement
which resulted in the capture of the rebel ram Tennessee and the damaging
of Fort Morgan, carrying on until obliged to go to the surgeon to whom
he reported himself as "only slightly injured." He then assisted in taking
care of the wounded below and wanted to be allowed to return to his battle
station on deck. Upon close examination it was found that he was wounded
quite severely in both eyes.
