The baggage plays an important part on the field as well as during cameos or pre-battle displays.
Members of the baggage follow the pike and musket blocks and administer water and support services to the regiment before, during and after a battle. During major musters the baggage from the whole army is often amalgamated to take part in the opening scenes, which could include being attacked by infantry or cavalry.
Without the ladies carrying water, the battles could not take place - something you will quickly realise when you take the field.
"Ladies!" is the order the soldiers wait to hear, panting for breath and longing for a drink!
