Gibbs, both from the point and from the farmer direct, that Red Soldiers have been seen on road to north leading to Center Mills. Lieut. Gibbs on arrival at 582 sends out a squad under Sergt. Jones to patrol north on the Center Mills road half a mile, then east by farm road to corner, then by fence south of house and barn to Opossum Creek and down creek to main road again. The advance party then proceeds about 300 yards easterly from 582, when the point signals "Enemy in small numbers in creek bottom due north." (a) What does Lieut. Gibbs and the advance party do? (b) What does he tell the point to do? (c) What does the flank patrol under Sergt. Jones do?

Robinson of Support No. 1. You are ordered by its commander to move out with 3 squads to form a picket, outguard No. 1, putting out observation posts on the road about half a mile south of the support. (a) State what directions you give to your picket and how you move to your position. (b) Where do you post the picket and its observation posts? (c) What orders and instructions do you give on arrival at the place selected? CHAPTER 15. Trench Warfare. General Principles. 1. Defense may be made in depth by all organizations, down to and including the platoon, or it may be made laterally. 2. The smallest active segment, be it only three men, must have a chief and a second in command, who is responsible for the proper upkeep and defense of the segment. All occupants of active segments must know all instructions which should be simple. 3. Any troops in charge of a portion of trench must never abandon it, no matter what happens, even if surrounded.
