The greatest numbers of casualties incurred by the regiment was during its service on Folly Island during the siege of Charleston, South Carolina. Contaminated drinking water caused severe illnesses amongst almost the entire regiment. So many men became ill with diarrhea that a board of surgeons was appointed to determine which men would be eligible for furloughs so that they could recover from the sickness. A convalescent camp was established at St. Augustine, Florida where many of the men spent their illness-caused furloughs.[1]
The regiment lost 217 men during service: 2 officers and 37 enlisted men killed and mortally wounded and 4 officers and 174 enlisted men by disease. The most frequent causes of death listed for the many members of the Regiment who died of disease included typhoid fever and chronic diarrhoea.[2]
