Battery Basics
Searching for a place to begin can distract one from getting started. Until such time of commitment, distract yourself with a good source to peruse as well as admirable illustrations which can be viewed in The Instruction for Field Artillery, 1861.
Whether crew member or civilian, it's good to be familiar with terms and positions you may be witness to, if not participating in, out on the field.

Cannon Crew
Eight cannoneers are needed to fire field pieces. Five are at the gun--the gunner and cannoneers 1, 2, 3, 4. The gunner is in charge of the piece, he gives the commands and does the aiming. Cannoneers 1-4 actually load, clean and fire the gun. Cannoneer 5 runs the ammunition from the limber to the gun. Cannoneers 6 and 7 prepare ammunition and cut the fuses.
