Upon receiving my orders, I selected a small staff and proceeded to Europe in order to become familiar with conditions at the earliest possible moment. The warmth of our reception in England and France was only equalled by the readiness of the leaders of the Allied armies to assist us in every way. We met and considered the best ways of working together. The French and British armies could not be increased in strength and they had been unable to drive the enemy from his systems of trenches in Belgium and France. It was therefore necessary to plan for an American force large enough to turn the scale in favor of the Allies. The problem before us was one of the very greatest difficulty. The first step was the formation of a General Staff and I gave this my early attention. A well organized General Staff to put into effect the plans of the Commander in Chief is essential to a successful modern army. However capable divisions, battalions, and companies may be as units, success would be impossible unless they worked together. A well organized General Staff trained for war has not hitherto existed in our army. Under the Commander in Chief this staff must carry out the policy of the army as a whole and direct all the details of its preparation, support, and operation. As models to aid us, we had the veteran French General Staff and the experience of the British who had formed a staff to meet the demands of a great army. By selecting from each the features that best met our needs and helped by our own early experience in the war, our great General Staff system was completed. The General Staff is divided into five groups, each with its chief. G. 1 is in charge of the organization and equipment of troops, replacements, overseas shipment, and welfare associations; G. 2 has censorship, gathering and disseminating information, particularly concerning the enemy, preparation of maps, and all similar subjects; G. 3 is charged with all strategic studies and plans and the supervision of the movement of troops and of fighting; G. 4 co-ordinates questions of army supply, necessary construction, transport for troops going into battle, of hospitals and the movement of the sick and wounded; G. 5 supervises the various schools and has general direction of education and training.
