Initially, the British medical staff used buildings in the former Panzertruppenschule (school for Panzer troops) as an emergency hospital to treat the former inmates away from the disastrous conditions of the concentration camp.[4] On 21 April the first patients were moved to the new location, disinfected and issued with new clothing.[4] This movement of people was completed by 18 May and at that point the former barracks had around 12,000 hospital beds.[4] The British also moved the wounded German soldiers from the Wehrmacht Reservelazarett (reserve hospital, in a nearby spruce forest) to civilian hospitals and added the Reservelazarett to their hospital space.[4] This raised the number of available beds by a further 1,600.[4] Within the first four weeks almost 29,000 survivors from Belsen concentration camp were moved to the emergency hospital.[2]:28 Around 14,000 former inmates died after liberation despite the best efforts of the British Army, the British Red Cross and many others of various nationalities.[2]:29 By June 1945, around 11,000 of the former inmates still required emergency treatment.[5]:305
