I thought things were difficult in the hospitals at Le Mans owing to lack of equipment, but that was child's play compared to the structural difficulties of working a hospital on a train, especially when it stands still for several days. One man will have to die on the train if we don't move soon, but we are not full up yet.
Imagine a hospital as big as King's College Hospital all packed into a train, and having to be self-provisioned, watered, sanitated, lit, cleaned, doctored and nursed and staffed and officered, all within its own limits. No outside person can realize the difficulties except those who try to work it.
The patients are extraordinarily good and take everything as it comes (or as it doesn't come!) without any grumbling. Your day is taken up in rapidly deciding which of all the things that want doing you must let go undone; shall they be washed or fed, or beds made, or have their medicines, or their dressings done? You end in doing some of each in each carriage, or in washing them after dinner instead of before breakfast.
