It is true that many of the private clinics which form so marked a feature of the modern life of Switzerland had been vacated by their foreign clients on the outbreak of war; but, as an off-set to this relief, the mobilization of the Swiss Army threw a strain on the Sanitary Service and the available accommodation which, perhaps, more than counter-balanced the relief afforded by the withdrawal of the foreign element. The "Médecin d'Armée" did not, at the outset, therefore, find much relief from the release of the private clinics, and a good deal of improvization had to take place before the difficulty was satisfactorily overcome. Military and civil hospitals, already in being in the different regions, were set apart or partially utilized for the Interned, whilst other suitable buildings were commandeered, and were installed as hospitals or convalescent homes. As to the treatment in the camps, the methods adopted were of a varying nature. At Château d'Oex, the men were, in the first instance, distributed amongst the hotels and châlets, without much regard to the nature of their physical condition, but as soon as the doctors could get to work, the worst cases were weeded out and sent to the local hospital, the "Soldanelle." Less serious cases, and those awaiting their time and turn for surgical treatment, were dealt with in their own establishments. The "Soldanelle" contained about eighty beds, and had in pre-war days been equipped solely for the use of visitors requiring rest cures, or electric or light treatments. The equipment included electric and X-ray installations, but was deficient on the surgical side. This defect was made good by the "B.L.R.C.O." at Berne, who presented the hospital with the complete equipment for an operating theatre. A question in connection with this operating theatre was raised at the time by the "Médecin d'Armée," which is of some interest as illustrating the point of view of the Swiss Medical Staff in respect to the surgical treatment of serious cases. When I first suggested to Colonel Hauser the desirability of bringing this hospital up to date by the addition of an operating theatre, he threw cold water on the scheme, on the ground that Château d'Oex had never been intended as an operating centre, and its equipment as such might and would, probably, lead to the performance of operations by local surgeons, when such operations had best be left to the specialist. There was no gainsaying this argument, and for a time the matter was left in abeyance; but when an immediate operation had to be conducted at Château d'Oex, in a hastily improvised room, as the only means of saving the life of an officer suffering from acute appendicitis, the need for a suitable operating theatre again came prominently to notice, and Colonel Hauser gave his consent for its installation.
