_Lieutenant Barry_: “I would proceed cautiously in the direction of the sentinel post. When I figure I am within hearing distance I will give the recognition signal. The sentinel will give me the return signal and I will know everything is all right and be free to go up to him.” _Lieutenant Hunt_: “I do not understand this recognition signal proposition. Can the director enlighten us on that?” Explanation _The Director_: “Yes, we will go into that in a few minutes. Before doing so I wish to review and consider in detail this comparatively simple proposition of approaching a sentinel post at night. You must remember that the line of observation of an outpost is a ‘spooky’ place at night and that outpost sentinels are as easily flushed as a pheasant. Their nerves are strung to the breaking point. In every shadow an enemy lurks. They soon learn to take no chances. It becomes the rule to shoot first and challenge afterwards. If one makes a practice of running headlong into sentinel posts on dark nights he may get away with it a few times, but you are taking serious chances and the game will finally get you. Having these things in mind, let us review the process of approaching the sentinel post. “1. The patrol leader halts his patrol some little distance from the post. He gives the orders for the other members to stand fast until he returns. He then goes to the outguard and notifies them that he is going out to the sentinel. There is no necessity for any other person than the patrol commander going up to the post. If others go it makes just that much more confusion and adds that much more chance for lurking scouts to locate the post and get information. “2. The patrol leader advances towards the post and when he is near enough he calls in a low tone, ‘Visiting patrol,’ and continues to call until he is recognized. We never approach a sentinel post from the front at night and, if it can be avoided, never from a flank, always from the rear. “3. When the sentinel discovers the presence of the patrol leader he will verify his identity by calling upon him for the countersign. Corporal Canes gives the countersign, and the sentinel directs him to advance.
