7. You have been sent with two men to find out whether the Conewago is fordable at any point between Table Rock and Fidler, B-7. After some search you find a crossing directly south of the zero in the number 540 which marks the contour of that height. Some time ago you sent a written message to the effect that there was a picket located at the Logan farm house. You have finished searching thoroughly that part of the stream assigned to you, when a strong party of the enemy is seen approaching your position from A. Logan. You give your remaining man a verbal message. Each takes a separate route. 8. You are in charge of a small reconnoitering patrol going south from Boyd School House. As you approach the marsh (7-4¼5, bottom) at the west of the road, you see three pieces of artillery stuck in the mud up to their hubs. You find that the guns are 3 in. field pieces. While you are investigating their mechanism in order to confirm your opinion that they belong to hostile troops, about forty men of the enemy with ropes and tackle appear about 400 yards to the south. You hurry away under cover, and find a telephone. You send a verbal message over the wire at twenty minutes to five in the evening. 9. You are delivering a message by motor cycle from Center Mills to Granite Hill Station. You are riding at about thirty miles an hour on a road supposedly clear of the enemy, when you are met by a fusillade from the woods in the vicinity of Henderson Meeting House. As you pass the road-fork, shots follow you and you feel a sharp pain in the calf of your leg. You speed up to pass the cross-roads at Hunterstown, and in two minutes reach Granite Hill Station. At twenty minutes after nine in the morning you dismount from your motor cycle and direct an infantryman standing near you to take a verbal message to headquarters in addition to the written one you hand him. 10. You are Captain Williams in command of Company B, 1st Battalion, 24th Infantry. You are acting as a support during the Outpost duty of your battalion. You are at 592, northwest of the Good Intent School House, D-7, and are engaged in driving back a company of infantrymen which is attacking you from the stream to the west. At twenty-five minutes to ten in the morning you are suddenly attacked also by a platoon of infantry from the direction of Herman. The nearest friendly troops are those at battalion headquarters. You are in a serious predicament. You at once send a verbal message by an intelligent sergeant. * * * * * We have doubtless demonstrated to our own satisfaction by means of the problems above how difficult it is to frame a message briefly and unmistakably. It might be well to inquire why we have had this trouble. An analysis may not only reveal, but also remedy, the cause of our inability to achieve the desired result.
