2. Duty of visiting patrol to investigate suspicious occurrences on outpost line. 3. Question of Patrol from outguard. 4. Visiting patrol makes reconnaissance. Two men brought up to sentinel post as a reserve. Outguard to remain in place at the alert. 5. Orders. * * * * * Procedure The class is now conducted to a point about 100 yards to the front of the sentinel post of Outguard No. 3, where Situation No. 7 is distributed and such explanation as may be necessary is made. The Problem =Situation No. 7=: You have arrived at this point. You discover a cavalryman’s horse, fully equipped, tied to that tree. You reconnoiter the vicinity but can find no other signs of the enemy. _Required_: What action do you take? Solution _The Director_: “Lieutenant Williams, how do you size up the situation?” _Lieutenant Williams_: “I have come to the conclusion that the enemy prisoner told the truth when he said he was lost. I do not believe there are any other men of the enemy in this immediate vicinity. Had there been other men with the prisoner he surely would not have dismounted and tied his horse to a tree. If there were more in the party one man would have been left out here to hold the horse while the prisoner went forward to reconnoiter on foot. I arrive at the conclusion that this is his horse and that he is a member of the enemy patrol that was operating over on the right of our line. He got lost and was trying to find some of the men of his own patrol when he ran into us. I do not think he realized that he was inside of our lines at the time he was captured.” _The Director_: “Has any member of the class a different version of the affair than what Lieutenant Williams has just explained?” _Captain Hastings_: “I do not think we would be justified in assuming that there are no more of the enemy in this vicinity. Two enemy scouts have been captured that we know of. These two men were not scouting around here alone. There must be more of them somewhere. It may be that others have come in contact with our outguards that we have not heard about.” _The Director_: “Have you heard any firing tonight along our lines?” _Captain Hastings_: “No, sir.” _The Director_: “Don’t you think that if there had been very much enemy activity along our lines that there would have been firing somewhere? I think it is fair to assume that. I believe we would be pretty well justified in assuming that the enemy activity is limited to perhaps a patrol from which our prisoner became lost. “The question now before us is what are we going to do? Lieutenant Wallace, what would you do?” _Lieutenant Wallace_: “I would get this horse back as quickly as possible and then I would extend my reconnaissance farther to the front.” _The Director_: “Where would you send the horse?”
