Half Files, Doubling the Front Inward Intire
"Half Files, double your front inward intire!"
That command reads and sounds complicated. But it's not when you break down the command into its components:
That's not so hard! The procedure is essentially in two parts as illustrated above:
As the illustration suggests, this may work well with a small number of soldiers to convert a column into a battle position with the musketeers placed at the sides (a.k.a., sleeves or wings). Hint: think small re-enactment event with few re-enactors.
Colonel Barriffe mentions this maneuver may also be applied to very large units, such as whole regiments. Consider a battle situation in which one regiment is already bloodied and weary. The commander brings forth from the reserves a fresh regiment which he situates right behind the center of the embattled regiment. The embattled regiment is then ordered to split and shift to each side (where there may be less fighting) and the fresh regiment surges into action. (Chapt 22, pg 28, Military Discipline...)
The reduction of this is: "Rear Half Files face about and march. Front Half Files, close your division. Face all to your leader."
