I suspect that your looking for a particular regiment. That is why I included the superior units these regiments were attached to and the inclusion of their commanders. It may help to narrow your search.

* Heavy artillery regiments were not, in the field, involved in artillery but served as infantry. These units were brought from artillery garrison duties from up north, mostly from the fortresses around Washington DC.
