Although the Union Army units which participated in the siege of Port Hudson are known, I have found no good sources for lists of the personnel who actually served there.  The following list is very small, and consists of the commanding officers, and the names of other officers and soldiers which I have found mentioned in books, letters, and other sources.  The published histories of some of the Union regiments which served at Port Hudson contain complete rosters of the regiment, but I have not added these lists in total, since undoubtedly many soldiers included were not actually present at Port Hudson.   Some of these books do have detailed casualty lists broken down by engagement, which have been a good source of soldiers who fought at Port Hudson.  My recent effort has been to add to the list the names of the men who were killed, wounded, or died of disease as a result of their Port Hudson service.

The hot, humid weather and swampy, mosquito-infested environment at Port Hudson proved deadly to the Northern soldiers. The number of Union troops who died due to disease is staggering, and far exceeds the number who were killed in battle or died from wounds.  The Fifteenth New Hampshire Regiment, a nine-month unit, had 32 deaths from combat or wounds, and 151 deaths from disease.  Many of the sick men continued to die months after the Port Hudson siege ended, after they had returned home.  Some of the causes of death listed include malaria, diphtheria, typhoid, climatic fever, or simply fever.  Other Northern regiments suffered similarly.

There were reportedly over 30,000 Union troops under General Banks' command at Port Hudson at one time during the siege, so there are plenty of names to be found.   If anyone has names of soldiers who are known to have been present during the siege, please send them for inclusion.
