To deal with these points that hold out, as well as with hostile reinforcements which may arrive, the reserve is launched into action, which brings the attack into the open ground beyond the second line of defense, and maneuver operations are begun. The mobile units are rapidly thrown into action, and large forces from the general reserve are hurried to the point where the lines of defense are broken through. From what has gone before we may deduce that the following conditions must prevail to attain success in an attack on a prepared position: 1. The attack must be planned down to the most minute detail. 2. There must be a greatly superior force of artillery concentrated at the point of attack, and the artillery preparation must be thorough. 3. The infantry must be sufficient in number, training and morale to perform the tasks that will be demanded of them. 4. The arrangements for the supply of ammunition to the firing line must be planned and carried out in all its details. 5. Plans for meeting counter attacks must be thorough and complete. The capture of a position is often less difficult than its retention. 6. Finally, every officer and man must know exactly what he is to do. Scouting and Patrolling By Capt. W. H.

Comment from Leading Officers of the Army “I have a copy of ‘Scouting and Patrolling’ and wish every other person in the military service had one. You have presented an interesting and very important subject in a very convenient, readable form and in its logical sequence. I commend the book to all soldiers. They will benefit by a careful study of its contents.” “The most complete and valuable treatise on scout and patrol work that has been published. The small size and shape of the little volume make it a convenient pocket reference book suitable for field work.” “It covers the duties that will fall to the lot of the soldier in time of war better than any work heretofore published. I predict that every company commander in the Army will eventually use it as a text-book in the instruction of his organization.” “Your book is excellent. I am amazed at the great amount of information you have concentrated in such a small volume. I shall certainly recommend it to the captains of my regiment as a book for instruction in noncommissioned officers’ schools. I feel that I should congratulate you on it as an American text-book on the subject that is far superior to any of the foreign publications.”
