The respective group is a collective effort of several campaigner grade authentic artillery battery's that frequently work together to form artillery sections or sometimes whole batteries... for a given historical portrayal reflective of time and place... In this case at Cedar Mountain we were guns portraying either Knap's Battery (US) or Pogues Battery (CS)... We all do both US or CS as the venue may necessitate.. Most times we have at least two guns that can be horse drawn... Habitually a rarity at most reenactments or living history programs due to the expense and logistical requirements to do so.. but so impressive to have the horses, limbers and guns come thundering in, drop and spin around into action front.... very physically demanding... and much different than the usual static gun demo's. We also use authentic period artillery drill rather than what is commonly seen by most being used at majority of mainstream events... which is entirely different...
