Good description. I would add that IIRC the prescribed US spacing between unlimbered guns (14 yards) was based on bringing the limber through.When in battery the Limber should be facing the gun. (Limber pole / horses facing towards the gun) Hence cannoneer #6 tending the limber stands at the limber facing towards the gun. Also so when the limber is opened it faces away from the action. When order is given to go, the horses-limber advances straight forward up along side of the gun. Cannoneers simply pick up the trail, turn it towards the back of the limber, move it inward about two feed til it can be hitched. A good trained detachment can have it limbered and on the move in less than a minute. The only implements that would normally need to be secured is the sponge-rammer, and the trail spike if it was used. If retiring by prolonge, the cannoneers just carry the implements along with them.
