It may interest my readers to hear something of our ambulance surgeons. Sir William MacCormac, who succeeded Marion Sims at Sedan, is now one of the greatest living authorities on military surgery and gunshot wounds. His colleague Dr. Mackellar is distinguished on the staff of St. Thomas's Hospital, and Dr. Parker is an eminent London specialist. The others, scattered over the face of the globe, I have lost sight of, but would fain hope one day to meet some of them again. One object I have had in view in publishing these notes may be worthy of mention. As I have tried to write down exactly what I witnessed, they may help to afford some idea of what war really means,--war as a hard practical fact--stripped of all the glamour, and poetry, and pride of conquest, that are so attractive when seen in history. Even from my own observations I could gather that all is not victory to the victors themselves. When the German soldiery learnt that Louis Napoléon was present in the trap at Sedan, there broke out among them the wildest exhibition of delight; for they believed--wrongly as it came to pass--that his capture would end the war and enable them to go back to their homes. And when peace was finally proclaimed, the Germans in Orleans were no less demonstrative and enthusiastic than the French, whose cup of suffering had been filled to overflowing. Now-a-days there is perhaps a tendency to undervalue this aspect of the case. People talk very lightly of the great European war that is said to be inevitable. It can do no harm to measure as far as possible what such a war may mean. Those who count the cost in advance are far more likely to be able to meet it, should the necessity arise, and to bear themselves resolutely and bravely to the end, whatever the event, than those who rush blindly forward, depending mainly on enthusiasm for organisation, and on the reputation of the past to achieve victories in the future. That seems to be the great lesson taught by the war of 1870 and 1871. There never was, perhaps, a more flagrant instance of disregard for that wise Shakesperian saying familiar to us all:-- "Beware Of entrance to a quarrel: but, being in, Bear it that the opposed may beware of thee". However, my readers will probably be disposed to form their own opinions on these subjects, and will have far more attractive material elsewhere on which to found them.
