The Medical Service is of immense importance to the operations. No General can afford to neglect his sick and wounded. He can hardly fight, if he knows he cannot attend to them on the battlefield, and remove them afterwards to hospitals in rear. There must be at the front sufficient surgeons, as well as medical appliances and stores, to cope with this work. The transport of the sick to the rear must be carried out without delay or confusion, and on the Lines of Communication, and at the Base, there must be properly equipped hospitals to receive the sick and wounded. The method of dealing with casualties in action is as follows: In the front, with the fighting men, are the regimental surgeons and the stretcher bearers of the Infantry, for work on the battlefield. Behind the fighting line are stretcher bearers and ambulance wagons of the Field Ambulance, collecting the wounded, and taking them to the dressing stations. In rear are the Clearing Hospitals, into which the sick and wounded are collected, and whence they are despatched in Ambulance Trains along the railway to Stationary Hospitals on the Lines of Communication, or to the Base Hospitals. The invalids are then removed, either to convalescent depôts on the L. of C., or by hospital ship to the home country, where civil organization can be depended on to help the Military Hospitals to deal with them. The Medical Services are manned and administered by the “Royal Army Medical Corps.” Their transport is provided by the Army Service Corps. The organization comprises the following: (_a_) WITH THE TROOPS AT THE FRONT 1. Medical Establishments with Units. 2. Field Ambulances with Subordinate Commands. (_b_) ON THE LINES OF COMMUNICATION Six Clearing Hospitals, at Advanced Base. Six Ambulance Railway Trains, each available for 100 patients lying down. Twelve Stationary Hospitals of 200 beds each, on the Lines of Communication. Twelve General Hospitals of 520 beds each, at the Base. Convalescent Depôts, as required. Six Hospital Ships, each to carry 220 patients. Three Base Depôts, and three Advanced Base Depôts, containing a reserve of Medical Stores. It will be observed that for a Division and a Brigade of Mounted Troops there are provided 1 Clearing Hospital, 1 Ambulance Train, 2 Stationary and 2 General Hospitals, and 1 Hospital Ship. DETAILS OF MEDICAL ORGANIZATION 1. Each Unit has attached to it a Medical Officer, and itself supplies two trained Orderlies, and a cart (or pack horse for mounted troops), to carry medical equipment. There are also two trained stretcher bearers from the ranks of each Infantry Company (or four men from each Squadron), trained in “first-aid” duties. 2. _Field Ambulances_ are allotted to each Division, and _Cavalry Field Ambulances_ to the Cavalry Division, and to the Mounted Brigades. They are provided on the scale of one for each Brigade. There are also two _Field Ambulances_ for the “Army Troops.”
