A town or camp is chosen and defended by all the Scouts present, except one patrol. The outposts must be carefully placed all round. The one patrol is to be led into the town by a guide chosen from the defenders--he is the traitor and goes round and carefully examines the defenses; then slips out of the town to meet the patrol at a certain spot. He tries to guide them into the center of the town, perhaps taking them two or three a time or all together in line. If touched by one of the defenders they are captured.
