In these problems all necessary data will be given. No attempt will be made to mislead in regard to fact. But every attempt will be made to mislead in regard to the expression of the fact. Crude violations and mixtures of rhetoric will therefore be found throughout. In arranging his material the student should use his own style and should not attempt to copy phraseology from any military forms. _That which is most brief and most unmistakable is best, no matter who writes the order._ _Note._—The topographical data will not be found upon the map. The units for which a field order must be written require an area larger than that which our limited sheet provides. The student, by reading over the problem two or three times ought, with the aid of his imagination, to perceive the will of the commander. (1) MARCH ORDERS 1.—On June 12, 1925, you are Major General Abercrombie in command of the 16th Division of the 12th Army Corps. You wish your division, which is in the vicinity of Bruceville, to march over to Littlestown the next day. You want it to cover the base and line of supply for your troops. You want it to do all this because one of your flying corps lieutenants saw from a captive balloon about a division of the enemy pass through Chambersburg early in the morning. The enemy was marching east and according to the lieutenant was composed of infantry, cavalry, field artillery—in fact, all branches of the service. You finish with this your twenty-second order since January 1st at a quarter after ten at night. But just before you finish with your order a Colonel of Cavalry on your staff tells you that he personally saw cavalry in Gettysburg during the evening. You want your advance guard, which consists of the 1st Brigade, 1st Battalion of the 1st Field Artillery, Company A, First Battalion of Engineers, one section of a Signal Company, and the first ambulance company, to get past the bridge over Pipe Creek at precisely six o’clock and to go along the main road to Littlestown in its route. The advance guard is to be commanded by Brigadier General Black. Now the main body, you figure, will go along in column from front to rear,—one section of the Signal Company, the fourth regiment of Infantry, the Field Artillery Brigade without its combat train, the 2d Brigade without the 4th Infantry, the third Brigade, the Signal Company (Company A) without its detachments, the first Battalion of Engineers without Company A, the Field Artillery Combat Train, and then the second, third, and fourth Ambulance companies.
